Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation transistor production, in particular to a transistor pin sleeve assembly machine. Background Art

[0002] Several transistors are needed in the control circuits of electrical equipment such as charging piles and mobile power supplies. Transistors are prone to high temperature during operation, so the transistors need to be locked on a heat sink to dissipate heat. Currently, before the transistors are locked on the heat sink, they need to be covered with foot covers on the pins of the transistors to prevent the transistors from being conductive to the heat sink.

[0003] At present, in the process of transistor assembly, manual operation is usually required to put the foot cover into the pin. However, due to the narrow distance between the pins and the small foot cover, this operation is prone to cause obvious deviation of the assembly position and low efficiency. Therefore, a semi-automatic machine equipment specially used for fitting foot covers is introduced, which can improve production efficiency to a certain extent. The semi-automatic machine equipment usually includes a handling robot. After the handling robot carries the transistor to the assembly station, the position of the transistor still needs to be locked to avoid the transistor from being offset and ensure the assembly quality.

[0004] Then in the above structure, since the handling robot needs to lock the transistor all the time when assembling the transistor, the handling robot needs to wait until the transistor is assembled before it can grab the material again, resulting in low handling efficiency and thus reduced production efficiency.

[0058] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0059] The present utility model embodiment provides a transistor lead sleeve assembly machine 1000, such as Figure 1 to Figure 2 The transistor lead sleeve assembly machine 1000 is provided with a first direction (such as Figure 1The machine 10 includes a loading station, a sleeve station and a unloading station arranged in sequence on the machine 10 (as shown in the X direction in FIG), which also includes a machine table 10, a material moving device 11, a limiting device 12 and a foot cover fitting device 13; the material moving device 11, the limiting device 12 and the foot cover fitting device 13 are all installed on the machine table 10, the material moving device 11 is used to synchronously drive the transistor 20 on the loading station and the sleeve station in the first direction; the limiting device 12 is used to position the transistor 20 on the sleeve station; the limiting device 12 and the material moving device 11 are operated alternately to cooperate; the foot cover fitting device 13 is used to fit the foot cover onto the pin 21 of the transistor 20 located at the sleeve station.

[0060] During the process of assembling the transistor 20 by the transistor lead sleeve assembly machine 1000 of the present application, the limiting device 12 and the material moving device 11 can operate alternately, so that the material moving process is faster and the assembly efficiency is higher, thereby improving the production efficiency.

[0061] Specifically, the material moving device 11 can transport the transistor 20 to be assembled at the loading station along the first direction to the sleeve station corresponding to the foot sleeve fitting device 13, and the limiting device 12 can limit and lock the transistor 20 to be assembled when the material moving device 11 transfers the transistor 20 to be assembled to the sleeve station, so that the material moving device 11 can release the transistor 20 at the sleeve station, reset it to the loading station, and lock the transistors 20 at the loading station and the sleeve station again. At this time, the limiting device 12 unlocks the transistor 20 to be assembled, and the foot sleeve fitting device 13 synchronously completes the sleeve of the transistor 20, and the material moving device 11 can quickly complete the material moving again, so that the assembled transistor 20 is transported to the unloading station, and the transistor 20 at the loading station is transported to the sleeve station, and the cycle assembly is restarted. It can be seen that the transistor lead sleeve assembly machine 1000 has a shorter stay time when transporting and moving materials, and can quickly complete unloading and reloading after the transistor 20 is assembled, with higher assembly efficiency, thereby improving the overall production efficiency.

[0062] In addition, during the transistor 20 assembly process of the transistor pin sleeve assembly machine 1000 of the present application, the limiting device 12 and the material moving device 11 can alternately cooperate to limit the transistor 20 at the assembly station, which enables the transistor 20 to be accurately positioned during the assembly process and not easily displaced, thereby enabling the pin sleeve to be accurately mounted on the correct pin 21, greatly improving the quality of the assembled product.

[0063] It should be noted that the limiting device 12 and the material moving device 11 in the present application operate alternately, wherein the alternating operation means that when the material moving device 11 is transporting and moving materials, the limiting device 12 does not limit the transistor 20, and when the limiting device 12 limits the transistor 20, the material moving device 11 does not transport materials.

[0064] Reference Figure 3 and Figure 4 In the present application, the limiting device 12 includes a limiting seat 121, a limiting assembly 122 and a first horizontal driving assembly 123; the limiting seat 121 is installed on the machine 10, and the limiting assembly 122 and the limiting seat 121 are in the second direction (such as Figure 1 The first horizontal driving assembly 123 is installed on the machine table 10 and connected to the limiting assembly 122. The first horizontal driving assembly 123 is used to drive the limiting assembly 122 to move in the second direction so that the limiting assembly 122 can cooperate with the limiting seat 121 to fix the transistor 20. In this way, when the transistor 20 is at the casing station, the limiting seat 121 and the limiting assembly 122 can better accurately position the transistor 20, which is convenient for rapid assembly.

[0065] Specifically, the first horizontal driving component 123 is a cylinder, and the first horizontal driving component 123 can be installed on the limit seat 121, which is convenient for installation and is conducive to connecting the limit component 122. The limit component 122 and the limit seat 121 are located on both sides of the transistor 20 in the second direction. The first horizontal driving component 123 drives the limit component 122, so that the transistor 20 is clamped between the limit component 122 and the limit seat 121, thereby realizing rapid locking and unlocking of the transistor 20 and improving assembly efficiency.

[0066] Further, refer to Figure 5 and Figure 6 The limiting assembly 122 includes a fixing seat 122a, a positioning member 122b and a first elastic member 122c. The fixing seat 122a is connected to the first horizontal driving assembly 123. The positioning member 122b is slidably connected to the fixing seat 122a in the second direction. The first elastic member 122c is installed in the fixing seat 122a and connected to the positioning member 122b, so that the fixing seat 122a can be elastically pressed against the transistor 20. In this way, the limiting device 12 is elastically locked when locking the transistor 20, which can prevent it from damaging the transistor 20, and the reliability of the limiting device 12 is stronger.

[0067] Specifically, the fixing seat 122a can be slidably connected to the limiting seat 121 to provide guidance for the fixing seat 122a, so as to facilitate the first horizontal driving component 123 to apply force, and the positioning member 122b is slidably connected to the fixing seat 122a, and the positioning member 122b can more accurately position the transistor 20 to prevent displacement when locked. The first elastic member 122c is a spring, which can make the positioning member 122b always have a tendency to move toward the transistor 20 in the second direction, and after the positioning member 122b contacts the transistor 20, the first elastic member 122c is compressed and stored to provide a buffer for the positioning member 122b, so that the positioning member 122b limits the transistor 20 through elastic force, so as to prevent the first horizontal driving component 123 from applying too much force, directly causing the positioning member 122b to damage the transistor 20.

[0068] Exemplarily, in the present application, the fixed seat 122a is connected to the limiting seat 121 through a slide rail, and a slide groove matching the positioning member 122b is provided on the fixed seat 122a, and the positioning member 122b slides in the slide groove, which is more convenient for installation; the first elastic member 122c is accommodated in the slide groove, which is convenient for cooperation with the positioning member 122b.

[0069] Preferably, in this embodiment, a profiling groove 122 d is provided on a side of the positioning member 122 b facing the transistor 20 , and the profiling groove 122 d is adapted to the outer contour of the transistor 20 in contact with the positioning member 122 b to improve the limiting effect on the transistor 20 .

[0070] Reference Figure 7 In the present application, the material moving device 11 includes a moving member 111, a second horizontal driving assembly 112 and a third horizontal driving assembly 113. The limit seat 121 is extended in the first direction, and the moving member 111 is arranged adjacent to the limit seat 121 in the second direction. The third horizontal driving assembly 113 is used to drive the moving member 111 to move in the second direction, so that the moving member 111 can cooperate with the limit seat 121 to fix the transistor 20. The second horizontal driving assembly 112 is used to drive the moving member 111 to move in the first direction to drive the transistor 20 to the next station. In this way, the limit seat 121 cooperates with the moving member 111, so that the moving member 111 can accurately position and carry the transistor 20 at each station, and the reliability of the material moving device 11 is stronger.

[0071] Specifically, the second horizontal drive component 112 and the third horizontal drive component 113 are both cylinders. The second horizontal drive component 112 can be installed on the limit seat 121, and the third horizontal drive component 113 is connected to the output end of the second horizontal drive component 112, and the moving part 111 is connected to the output end of the third horizontal drive component 113, so that the second horizontal drive component 112 and the third horizontal drive component 113 can apply force to the moving part 111. The limit seat 121 is extended in the first direction, so that the moving part 111 can simultaneously lock multiple transistors 20 at the workstation after cooperating with it, thereby completing the transportation action more efficiently.

[0072] Preferably, the second horizontal driving assembly 112, the third horizontal driving assembly 113 and the first horizontal driving assembly 123 can be arranged on both sides of the limiting seat 121, so that the layout is more reasonable and the installation space can be fully utilized, which is convenient for setting the moving part 111 and the fixed seat 122a.

[0073] Further, refer to Figure 8 The moving member 111 is provided with a plurality of notches 111a on one side facing the limiting seat 121. The plurality of notches 111a are arranged at intervals in the first direction, and the notches 111a are used to accommodate the transistor 20. In this way, the notches 111a can improve the limiting effect of the transistor 20, making the material moving device 11 more accurate in handling and positioning.

[0074] Specifically, the plurality of notches 111a can enable the material transfer device 11 to sequentially transfer multiple transistors 20 between adjacent workstations at equal intervals, and can also simultaneously complete the loading and unloading of materials after assembly, which is more efficient. The contour of the notch 111a can be adapted to the outer contour of the transistor 20 to more accurately transport the transistor 20 to the next workstation.

[0075] Reference Fig. 9 and Fig.10 In one embodiment, the limiting seat 121 includes a first extension portion 121a, a second extension portion 121b and a bottom support portion 121c, the first extension portion 121a and the second extension portion 121b are disposed on the bottom support portion 121c, and the two are spaced apart in the second direction to form a guide groove 121d; the transistor 20 includes a main body 22 connected to the pin 21, a part of the main body 22 is accommodated in the guide groove 121d, and the other part is exposed outside the guide groove 121d, and the positioning member 122b, the moving member 111 and the guide groove 121d are in the gravity direction (such as Figure 1The first extension 121a and the second extension 121b are arranged in a staggered manner in the second direction. When the transistor 20 moves in the first direction, the guide groove 121d can provide guidance. The main body 22 of the transistor 20 can be accommodated in the guide groove 121d and can cooperate with the positioning member 122b and the moving member 111 to achieve more accurate locking or transportation of the transistor 20. The bottom support 121c can support the transistor 20, so that the transportation device only needs to provide a driving force greater than the sliding friction force of the transistor 20 in the guide groove 121d to complete the transportation, and the transportation process is easier. The positioning member 122b, the moving member 111 and the guide groove 121d are arranged in a staggered manner in the direction of gravity, which can completely avoid interference and collision when the devices act on each other, so that the transistor lead sleeve assembly machine 1000 can operate more safely.

[0076] Preferably, in this embodiment, the first extension portion 121a is in a third direction (eg Figure 1 A second extension portion 121b is protruded on the upper side (as shown in the P direction) to increase the contact area between the main body 22 and the first extension portion 121a. When the positioning member 122b and the moving member 111 limit the transistor 20, the main body 22 of the transistor 20 can completely rest on the first extension portion 121a, making the fixation more secure.

[0077] Reference Fig.11 In one embodiment, the pin sleeve assembly device 13 includes a sleeve supply mechanism 131, a swing mechanism 132, and a cutter 133 arranged in sequence in the direction of gravity. The sleeve supply mechanism 131 is used to supply the pin sleeve to the transistor 20. The cutter 133 is connected to the swing mechanism 132. The swing mechanism 132 is used to drive the cutter 133 to cut the pin sleeve. With such a configuration, when the transistor lead sleeve assembly machine 1000 is assembled, the pin sleeve can automatically complete the loading and assembly, reducing manual intervention and improving assembly efficiency.

[0078] Specifically, the sleeve supply mechanism 131 includes a first rotating drive component 131a, a first transmission component 131b and two guide wheels 131c. The first rotating drive component 131a can be a motor. The first rotating drive component 131a is connected to the first transmission component 131b. There are many ways to set the first transmission component 131b. For example, it can be transmitted by setting a synchronous belt and a synchronous wheel. The first transmission component 131b is connected to one of the guide wheels 131c, and the foot cover is arranged between the two guide wheels 131c. The rotation axis of the guide wheel 131c is consistent with the first direction, so that the first rotating drive component 131a drives the guide wheel 131c to rotate through the first transmission component 131b, so that the foot cover moves in the direction of gravity, and then the foot cover is sleeved on the pin 21. In addition, the foot cover can also be circled into a material tray and rotatably connected to the machine 10 to continuously provide materials to the sleeve supply mechanism 131.

[0079] Reference Fig.12 The swing mechanism 132 includes a fourth horizontal driving component 132a and a connecting rod 132b. The fourth horizontal driving component 132a is a cylinder, and its output end is connected to one end of the connecting rod 132b. The middle part of the connecting rod 132b is rotatably connected to the machine 10, and its rotation axis extends along the gravity direction, so that the linear motion of the fourth horizontal driving component 132a in the second direction can be converted into the rotation of the connecting rod 132b. The cutter 133 is arranged between the pin 21 and the guide wheel 131c in the gravity direction, and is connected to the other end of the connecting rod 132b, and the rotation of the connecting rod 132b can make the cutter 133 swing to cut off the foot cover. The advantage of this design is that when a single transistor 20 has multiple pins 21 that need to be covered with multiple foot covers, the cutter 133 can better apply force to the multiple foot covers to cut them off. For example, in the present application, a single transistor 20 is provided with three pins 21 spaced apart along a first direction. When the transistor 20 is assembled, the cutting process of the cutter 133 is to cut off the pin sleeves one by one. Cutting off the pin sleeves one by one can reduce the resistance encountered by the cutter 133 compared with cutting off multiple pin sleeves at the same time, thereby making it easier for the cutter 133 to complete the cutting action and avoiding jamming.

[0080] Preferably, refer to Fig.12 and Fig.13 In this embodiment, the foot sleeve set device 13 also includes a catheter seat 134, and the catheter seat 134 is provided with a through groove 134a for the foot sleeve to pass through in the gravity direction. The through groove 134a is arranged opposite to the pin 21 at the sleeve station. The catheter seat 134 is provided with an avoidance groove 134b connected with the through groove 134a in the second direction. In this way, the through groove 134a can limit and guide the foot sleeve, and the avoidance groove 134b allows the cutter 133 to be placed in the through groove 134a to cut off the foot sleeve, and the cut foot sleeve will not shift due to the through groove 134a for limiting, and can be accurately inserted into the corresponding pin 21, and the assembly stability and reliability of the transistor pin sleeve assembly machine 1000 are further enhanced.

[0081] In order to make the foot cover more securely connected to the pin 21, a variety of settings are used in this application.

In the third embodiment, it is a combination of the first embodiment and the second embodiment.

[0082] Specifically, the dispensing device 14 includes a dispensing head 141 and an adjusting mechanism 142 . The adjusting mechanism 142 is installed on the machine platform. The dispensing head 141 is connected to the adjusting mechanism 142 . The adjusting mechanism 142 can align the dispensing head 141 with the pin 21 to perform dispensing more accurately.

[0083] The heating device 15 includes a heat source (not shown in the figure) and a heating box 151. The heating box 151 is provided with a heating chamber and a channel 151a running through the heating chamber. The heat source is connected to the heating chamber, and the channel 151a is extended along a first direction so that the transistor 20 can enter and exit the heating box 151 to achieve heating, so that the glue can be cured faster and / or the foot cover is hot-melted on the pin 21. Multiple heating stations can be set so that the heating box 151 can heat multiple transistors 20 simultaneously to improve the heating efficiency. Preferably, in the present application, the heating box 151 is also provided with a heat dissipation box 152, which is covered on the outside of the heating box 151 to dissipate heat from the heating box 151 in time to prevent excessive temperature from affecting the transistor 20.

[0084] Reference Fig.16 In one embodiment, the transistor lead sleeve assembly machine 1000 is further provided with a calibration station, which is arranged between the sleeve station and the material unloading station in the first direction. The transistor lead sleeve assembly machine 1000 also includes a calibration device 16, which is installed on the machine platform 10 and arranged corresponding to the calibration station. The material moving device 11 and the limiting device 12 also act on the transistor 20 at the calibration station. Such an arrangement ensures that the pin sleeve can be assembled to the preset position of the pin 21, thereby improving the quality of the assembled product.

[0085] Specifically, the calibration device 16 includes a first lifting drive component 161, a clamping drive component 162 and two clamping blocks 163. The first lifting drive component 161 can be a cylinder. The first lifting drive component 161 is connected to the clamping drive component 162. The first lifting drive component 161 drives the clamping drive component 162 to rise and fall. The clamping drive component 162 can be a clamping cylinder. The clamping drive component 162 can drive the two clamping blocks 163 to move toward each other in the second direction to clamp the foot cover, thereby driving the foot cover to move to a preset position.

[0086] Preferably, multiple calibration stations can be provided. For example, in the present embodiment, two calibration stations are provided. Two clamping blocks 163 are both extended along the first direction to simultaneously clamp the foot covers at the two calibration stations and drive them down to a preset position. This design enables one calibration device 16 to perform actions on multiple assembled transistors 20 at the same time, further improving efficiency.

[0087] Preferably, in this embodiment, the clamping block 163 is provided with a groove, and the groove is adapted to the foot cover so as to be in full contact with the foot cover, thereby increasing the friction between the two and better transferring the foot cover.

[0088] To ensure that pin 21 is compatible with the control circuits of different power bank and other power-consuming devices. Fig.17 and Fig.18 In the present application, the transistor lead sleeve assembly machine 1000 is also provided with a waste collection station, which is arranged between the heating station and the unloading station in the first direction. The transistor lead sleeve assembly machine 1000 also includes a waste cutting device 17, which is installed on the machine 10 and arranged corresponding to the waste collection station. The waste cutting device 17 is used to cut off the excess pins 21, and the material moving device 11 and the limiting device 12 also act on the transistor 20 at the waste collection station. With such a configuration, the waste cutting device 17 can cut according to the different length requirements of the pins 21 to adapt to different types of control circuits, thereby improving the scope of application of the transistor lead sleeve assembly machine 1000.

[0089] Specifically, the waste cutting device 17 includes a fifth horizontal driving component 171, a cutter seat 172, a top holding member 173, a fixing member 174 and a second elastic member 175. The cutter seat 172 is connected to the fifth horizontal driving component 171. The fifth horizontal driving component 171 is used to drive the cutter seat 172 to move in the second direction. The top holding member 173 is slidably connected to the cutter seat 172. The top holding member 173 and the fixing member 174 are arranged on both sides of the pin 21 in the second direction. The second elastic member 175 is installed in the cutter seat 172 and connected to the top holding member 173. When the top holding member 173 and the fixing member 174 clamp the pin 21, the second elastic member 175 is compressed to store energy, so that the cutter seat 172 cuts off the excess part of the pin 21, and resets the top holding member 173 when releasing the energy.

[0090] Exemplarily, the fifth horizontal driving component 171 is a cylinder, which drives the cutter seat 172 to move, and the supporting member 173 moves along with it, and before the cutter seat 172 cuts off the redundant pins 21, the supporting member 173 first clamps the pins 21 and the main body 22 with the fixing member 174 to prevent the entire pin 21 from bending and deforming when the cutter seat 172 cuts off the redundant pins 21. The second elastic member 175 is a spring, which provides elastic buffering when the supporting member 173 and the fixing member 174 clamp the pins 21, so as to prevent the pins 21 from being deformed due to excessive force when they are fixed.

[0091] Preferably, in this embodiment, the waste cutting device 17 also includes a waste box 176, and the fixing member 174 is provided with a waste port 174a, which is communicated with the waste box 176, and the waste port 174a is located at the end of the travel direction of the cutter seat 172. After the cutter seat 172 cuts off the excess pins 21, the waste can be pushed into the waste port 174a and then fall into the waste box 176, completing the waste collection and centralizing the waste for the convenience of workers to clean up.

[0092] Reference Fig.19 In one embodiment, the transistor lead sleeve assembly machine 1000 further includes a loading device 18, which includes a second rotary drive component 181, a rotating disk 182, and a first oscillating table 183. The rotating disk 182 is provided with a plurality of guide tubes 184 in the gravity direction. The guide tubes 184 are used to accommodate a transistor 20 group formed by stacking a plurality of transistors 20. The plurality of guide tubes 184 are arranged at intervals along the circumference of the rotating disk 182. The second rotary drive component 181 drives the rotating disk 182 to rotate so that one of the guide tubes 184 is aligned and connected with the first oscillating table 183. The first oscillating table 183 is used to drive the transistor 20 to be fed to the loading station. With such a configuration, automatic loading of the transistor 20 is realized, and a larger number of transistors 20 can be stored, which reduces the number of loading times of workers, shortens downtime, and improves production efficiency.

[0093] Specifically, the second rotary drive assembly 181 is a servo motor, and its output shaft is connected to the rotating disk 182, which can rotate to switch the alignment of different guide tubes 184 and the first straight vibration table 183. The transistor 20 is dropped into the first straight vibration table 183 along the length direction of the guide tube 184 by its own gravity, which simplifies the design and reduces the use of external power sources, thereby reducing the maintenance cost of the transistor lead sleeve assembly machine 1000.

[0094] Preferably, in this embodiment, the guide tube 184 is inserted vertically on the rotating disk 182. Compared with the embodiment in which the guide tube 184 is placed horizontally, the vertical placement of the guide tube 184 can more effectively utilize the space, so that the guide tubes 184 can be arranged more closely, thereby accommodating more guide tubes 184 in a limited space and reducing the number of loading times. In addition, since the transistor 20 is placed flat on the first straight vibration table 183, it can also prevent the transistor 20 from getting stuck at the bend where the two are connected and aligned.

[0095] Further, refer to Fig. 20 The loading device 18 also includes a steering mechanism 185, which is arranged between the limit seat 121 and the first straight vibration table 183. The steering mechanism 185 includes a rotating block 185a and a third rotation drive component 185f. The rotating block 185a includes two end faces 185b arranged opposite to each other in a first direction and a peripheral surface 185c connecting the two end faces 185b. The peripheral surface 185c is provided with a receiving groove 185d. The receiving groove 185d is used to receive the transistor 20. The groove wall of the receiving groove 185d passes through the two end faces 185b so that the receiving groove 185d is connected and aligned with the first straight vibration table 183; wherein the third rotation drive component 185f can drive the rotating block 185a to rotate, so that the receiving groove 185d is aligned with the limit seat 121 and the direction of the pin 21 is changed, so as to provide for the handling device to carry. Such arrangement allows the pins 21 of the flatly lying transistor 20 to enter the limiting seat 121 upward, which is helpful to prevent the foot cover from falling off from the pins 21 during transportation.

[0096] Reference Fig.21 In one embodiment, the transistor lead sleeve assembly machine 1000 also includes a blanking device 19, which includes a second vertical vibration table 191. The second vertical vibration table 191 can store and transport more assembled transistors 20, so that the transistors 20 at the blanking station can be discharged in time, which is convenient for subsequent equipment to take away.

[0097] The workflow of this application is as follows:

[0098] The assembly process of the transistor 20 generally includes the following steps: 1. Loading the semi-finished transistor 20; 2. Gluing the semi-finished transistor 20; 3. Installing the foot cover; 4. Calibrating the foot cover position; 5. Heating the foot cover; 6. Removing the redundant pins 21; and 7. Unloading the finished transistor 20.

[0099] In step 1, the semi-finished transistor 20 is transferred to the loading station by the loading device 18 so as to be aligned with the guide groove 121d of the limit seat 121. Between step 1 and step 2, the material transfer device 11 locks the semi-finished transistor 20 through the moving member 111 and transports it to the dispensing station. The limit device 12 drives the limit assembly 122 to lock the semi-finished transistor 20 in the guide groove 121d.

[0100] In step 2, the glue dispensing device 14 dispenses glue to the pin 21, and at the same time, the material moving device 11 is unlocked and reset, and the transistor 20 at the loading station is locked again; after the glue dispensing is completed, the limit device 12 is unlocked, and the material moving device 11 quickly moves the transistor 20 at the glue dispensing station to the sleeve station, and at the same time, the glue dispensing station is reloaded;

[0101] In step 3, the foot cover fitting device 13 loads the foot cover, and after the foot cover is fitted onto the pin 21, the foot cover is cut off so that it remains on the pin 21, completing the foot cover fitting. Then the material moving device 11 and the position limiting device 12 cyclically and alternately perform the same actions as between step 1 and step 2, so that the transistor 20 at the sleeve station is moved to the calibration station, and the sleeve station is reloaded;

[0102] In step 4, the calibration device 16 holds the foot cover and descends to the preset position of the pin 21, and then the material moving device 11 and the limiting device 12 perform actions alternately again in a cycle, so that the transistor 20 at the calibration station is moved to the heating station, and the calibration station is reloaded;

[0103] In step 5, the heating device 15 heats the foot cover to make it melt on the pin 21 and quickly solidify the glue; then the material moving device 11 and the limiting device 12 perform actions alternately again in a cycle, so that the transistor 20 at the heating station is moved to the waste collection station, and the heating station is reloaded at the same time;

[0104] In step 6, the waste collection device cuts off the redundant pins 21, and then the material moving device 11 and the limiting device 12 perform actions alternately again in a cycle, so that the transistors 20 at the waste collection location are moved to the unloading station, and the waste collection station is reloaded at the same time;

[0105] In step 7, the unloading device 19 temporarily stores and transports the finished transistors 20 for subsequent equipment to take away.

[0106] It should be noted that in the present application, the dispensing station, the sleeve station, the calibration station, the heating station and the waste collection station are all arranged in sequence in the first direction in the limit seat 121, and a plurality of limit components 122 are arranged on the limit device 12, and the plurality of limit components 122 are arranged corresponding to each station in the limit seat 121, so that when the limit device 12 performs an action, it can synchronously lock the plurality of stations, so that the transistors 20 on each station can simultaneously perform corresponding process actions; and there are also a plurality of notches 111a on the moving part 111 of the material transfer device 11. When the moving part 111 is in the reset state, the plurality of notches 111a are arranged corresponding to the loading station and each station in the limit seat 121, so when the moving part 111 moves along the first direction, the transistor 20 at the current station can be synchronously transferred to the next station, so as to simultaneously complete the loading, the transfer between the processes of each transistor 20 on the limit seat 121, and the unloading of the finished product.
