[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0035] Please see Figure 1 The diagram shown is a perspective view of the automated terminal pre-processing device 1 provided in this application embodiment after removing the upper part of the cabinet. The automated terminal pre-processing device 1 includes a material tray 12, a feeding mechanism 13, a cutting device 14, a loading mechanism 15, a cleaning device 16, a transfer device 17, a cleaning liquid tank 18, a processing liquid tank 19, a drying device 20, and a unloading mechanism 21.

[0036] Please also refer to Figure 2 The tray 12 is used to provide terminal strips 5. In this embodiment, the terminal strips 5 are wound around the rotating shaft of the tray 12 and include strip 51 and terminals 52. The terminals 52 are fixed to one side of the strip 51 and arranged at intervals along one side of the strip 51. A protective structure 53 is provided between the terminals 52. The protective structure 53 is connected to the side of the strip 51 and is used to protect the specific structure on the terminal 52 and prevent the specific structure from being crushed.

[0037] Please continue reading. Figure 1 The automated terminal pretreatment device 1 is also equipped with a track 22. After one end of the terminal strip 5 emerges from the tray 12, it can travel along the track 22, pass through the cutting device 14, and extend to the location of the feeding mechanism 15. Specifically, in this embodiment, the track 22 includes a front track 221, a middle track 222, and a rear track 223. A feeding mechanism 13 is provided between the front track 221 and the middle track 222, and a cutting device 14 is provided between the middle track 222 and the rear track 223. In other embodiments, the middle track 222 can be omitted, and the feeding mechanism 13 and the cutting device 14 are sequentially arranged between the front track 221 and the rear track 223. In this embodiment, the feeding mechanism 13 pulls the terminal strip 5 from the tray 12 and moves it along the track 22. The terminal strip 5 is cut into segments 54 by the cutting device 14, which also cuts off the protective structure 53 on the terminal strip 5. The cutting device 14 is adjacent to the rear track 223, and the segments 54 cut by the cutting device 14 are located on the rear track 223.

[0038] The cleaning device 16 is positioned after the rear track 223, and its extension direction is approximately perpendicular to that of the rear track 223. Specifically, the rear track 223 extends along a first direction w1, and the cleaning device 16 extends along a second direction w2, with the first direction w1 and the second direction w2 being approximately perpendicular. The feeding mechanism 15 is supported by two supports 151 and spans above the cleaning device 16. The feeding mechanism 15 includes a working module 150, which moves back and forth between the rear track 223 and the cleaning device 16 to transfer the material segments 54 cut by the cutting device 14 into the cleaning device 16.

[0039] The cleaning device 16 is a tank structure with a head end 161 and a tail end 162 along the second direction w2. The head end 161 is adjacent to the rear track 223 and has a feeding position. The tail end 162 is adjacent to the transfer device 17 and the cleaning liquid tank 18. The cleaning device 16 includes a transmission device 163 and fixing devices 164 fixed on the transmission device 163. The transmission device 163 is arranged and operates along the second direction w2. There are multiple fixing devices 164, which are spaced apart along the direction of operation of the transmission device 163, and are used to fix the material section 54. After the feeding mechanism 15 transfers the material segment 54 to a fixed device 164 located at the feeding position, the conveying device 163 moves forward a predetermined distance along the second direction w2, so that the next fixed device 164 is located at the feeding position, so that the feeding mechanism 15 can place the next material segment 54 on the fixed device 164. Thus, as the conveying device 163 moves forward, the material segment 54 is sequentially conveyed to the tail end 162 of the cleaning device 16. The cleaning device 16 contains cleaning fluid. When the material segment 54 is fixed to the fixed device 164, the cleaning fluid contacts the parts of the terminal 52 that need to be cleaned, and cleans the terminal 52 during the process of transporting the material segment 54 from the head end 161 to the tail end 162. Specifically, during the process of transporting the material segment 54 from the head end 161 to the tail end 162, the transported material segment 54 itself will vibrate. This vibration will increase the friction area and force between the cleaning fluid and the terminal 52, thereby helping to achieve a better cleaning effect. Furthermore, to further enhance the cleaning effect, the cleaning device 16 may further include a vibration device, which applies vibration to both the cleaning liquid and the terminal 52, thereby further increasing the frictional area and force between the cleaning liquid and the terminal 52, achieving a better cleaning effect. Specifically, in this embodiment, the vibration device is an ultrasonic device.

[0040] The transfer device 17 includes an operation module 170, which transfers the material segment 54 located at a specific position at the tail end 162 of the cleaning device 16 to the cleaning liquid tank 18. After the terminals 52 on the material segment 54 are cleaned by the cleaning liquid in the cleaning liquid tank 18, the operation module 170 transfers the material segment 54 to the treatment liquid tank 19. After that, the operation module 170 transfers the material segment 54 to the drying device 20.

[0041] The transfer device 17 extends along the third direction w3 and includes a head end 172, a tail end 173 and a middle section 174. The head end 172 is adjacent to the cleaning device 16, the tail end 173 is adjacent to the drying device 20, and the middle section 174 is adjacent to the cleaning liquid tank 18 and the treatment liquid tank 19.

[0042] The drying device 20 is a tank structure with a head end 201 and a tail end 202 along the fourth direction w4. The head end 201 is adjacent to the transfer device 17, and the tail end 202 is adjacent to the unloading mechanism 21. The drying device 20 includes a conveying device 203 and fixing devices 204 fixed to the conveying device 203. The conveying device 203 is arranged and operates along the fourth direction w4. Multiple fixing devices 204 are spaced apart along the direction of travel of the conveying device 203 and are used to fix the material segments 54. After the transfer device 17 transfers the material segment 54 to a fixing device 204 located at the loading position, the conveying device 203 moves forward a predetermined distance along the fourth direction w4, so that the next fixing device 204 is located at the loading position, allowing the transfer device 17 to place the next material segment 54 onto that fixing device 204. Thus, as the conveying device 203 moves forward, the material segments 54 are sequentially conveyed to the tail end 202 of the drying device 20.

[0043] During the process of transporting the material segment 54 from the head end 201 to the tail end 202, the transport segment 54 itself agitates the air, which is beneficial to the drying or curing of the treatment liquid on the terminal 52. In addition, to further improve the drying or curing effect, the drying device 20 may further include an air supply device or a heating device, depending on the needs.

[0044] The feeding mechanism 21 is supported by a support 211 and mounted above the tail end 202 of the drying device 20. The feeding mechanism 21 is arranged along a first direction w1 and includes a working module 210. The working module 210 moves the material segment 54 located at the feeding position at the tail end 202 of the drying device 20 out of the automated terminal pre-processing device 1. Thus, the automated terminal pre-processing device 1 completes the pre-processing of the terminals 52 on the material segment 54.

[0045] The automated terminal pretreatment device 1 also includes a plasma cleaning device 22, used to output (e.g., spray) plasma to clean the terminals 52, thereby activating the activity of the terminal surface material and improving the adhesion of the terminal surface. In this embodiment, there are two pairs of four plasma cleaning devices 22, each pair arranged opposite each other. The two pairs of plasma cleaning devices 22 are respectively arranged between the cleaning device 16 and the cleaning liquid tank 18, and between the treatment liquid tank 19 and the drying device 20. When the transfer device 17 transfers the material segment 54 from the cleaning device 16 to the cleaning liquid tank 18, and from the treatment liquid tank 19 to the drying device 20, the material segment passes through the plasma cleaning device 22, and the plasma cleaning device 22 outputs plasma to clean the terminals 52.

[0046] In this embodiment, the third direction w3 is parallel to the first direction w1, and the fourth direction w4 is opposite to the second direction w2. The main working components of the automated terminal pretreatment device 1 are arranged in a Z-shape. This achieves a compact layout and avoids complex motion designs for the working modules of the feeding mechanism 15, the transfer device 17, and the unloading device 21. For example, the orientation of the rear track 223 and the cleaning device 16 allows the working module 150 of the feeding mechanism 15 to move only up, down, left, and right, avoiding complex motion designs such as rotation. Similarly, the orientation of the transfer device 17 with the cleaning device 16, the cleaning liquid tank 18, the treatment liquid tank 19, and the drying device 20 also avoids complex motion designs such as rotation for the working module 170 of the transfer device 17.

[0047] In addition, since both the cleaning device 16 and the drying device 20 are designed with multiple rows of fixing devices on the conveying device, the material segment 54 can be received continuously, and the terminals 52 on the material segment 54 can be cleaned / dried for a longer period of time, so as to improve the pretreatment effect without affecting production efficiency.

[0048] The structure and operation of each major working component provided in the embodiments of this application are described in detail below.

[0049] Feeding mechanism 13

[0050] Please see Figure 3The diagram shown is a perspective view of a feeding mechanism 13 provided in one embodiment of this application. The feeding mechanism 13 includes a base 131, a guide rail module 132 mounted on the base 131, a power component 133, and a working module 134 mounted on the guide rail module 132. In this embodiment, the guide rail module 132 includes a guide rail 1321 extending along a first direction w1, with both ends mounted on the base 131. The power component 133 is also mounted on the base 131, and drives the working module 134 to move along the guide rail module 132, thereby realizing the movement of the working module 134 in the first direction w1. A sensing device 135 is also provided along the running path of the working module 134. The sensing device 135 can be a contact sensor used for controlling and resetting the reciprocating motion of the feeding mechanism 13. The working module 134 includes a mounting base 1340, a power component 1341, a guide rail module 1342, and a gripper module 1343. The mounting base 1340 is mounted on the guide rail module 132 and is driven by the power component 133 to move along the guide rail 1321. Furthermore, the power component 1341 is mounted on the mounting base 1340, and the guide rail module 1342 is mounted above the power component 1341. The guide rail module 1342 has a guide rail 13421 extending along a fifth direction w5, which is approximately perpendicular to the first direction w1. The gripper module 1343 is mounted on the guide rail module 1342 and has at least one pair of grippers 13431. Each pair of grippers 13431 is driven by the power component 1341 to move along the guide rail 13421, causing the two grippers 13431 to move closer or further apart, thereby gripping or releasing the terminal material strip 5. In this embodiment, both the power components 133 and 1341 are cylinders. In other embodiments, the power components 133 and 1341 can be other power-providing devices, such as stepper motors.

[0051] Specifically, in this embodiment, the gripper 13431 is located on the path of the terminal strip 5. The power unit 1341 drives the gripper 13431 to move under the control of a control device to grip the terminal strip 5. Then, under the control of the control device, the power unit 133 drives the working module 134 to move a predetermined distance on the guide rail module 132, thereby realizing the function of sending a terminal strip 5 of a predetermined length from the tray 12.

[0052] Cutting device 14

[0053] Please see Figure 4The diagram shown is a perspective view of a cutting device 14 provided in one embodiment of this application. The cutting device 14 includes a base 141, a power component 142, and a cutting module 143. In this embodiment, the power component 142 is mounted on the base 141, and the cutting module 143 includes a blade portion 1431 and a mating portion 1433. The blade portion 1431 and the mating portion 1433 are disposed opposite to each other. In this embodiment, the blade portion 1431 is mounted at the end of the power component 142 and is driven by the power component 142 to reciprocate along the second direction w2 and the fourth direction w4. The mating portion 1433 is disposed on the base 141 and is opposite to the blade portion 1431. The cutting edge 1431 includes a first cutting edge 14311 and a second cutting edge 14312 arranged sequentially along a first direction. The first cutting edge 14311 is positioned away from the rear guide rail 223, and the second cutting edge 14311 is positioned close to the rear guide rail 223. The second cutting edge 14311 is used to cut the terminal strip 5, forming a segment 54 of a preset length on the terminal strip 5 located on the rear guide rail 223. There are multiple first cutting edges 14311, the number of which corresponds to the number of terminals 52 on the segment 54 of the preset length. The multiple first cutting edges 14311 are arranged in a line along the first direction w1 to achieve the purpose of the protective structure 53 on the side where the terminals are cut.

[0054] Specifically, in this embodiment, when no cutting action is performed, there is a gap 1434 between the blade portion 1431 and the mating portion 1433. The gap 1434 is approximately aligned with the rear track 223, and the terminal strip 5 passes through the gap 1434. The terminals 52 and protective structures 53 on the terminal strip 5 are located outside the gap 1434. When the cutting action is performed, the power unit 142 drives the blade portion 1431 to move toward the mating portion 1433. The first blade 14311 cooperates with the mating portion 1433 to cut the protective structure 53 on the material segment 54 within a preset length. The second blade 14312 cooperates with the mating portion 1433 to cut the terminal strip 55, so that the terminal strip 5 located on the rear guide rail 223 becomes an independent material segment 54 of a preset length.

[0055] In this embodiment, the power component 142 is a cylinder. In other embodiments, the power component 142 may also be a motor or a combination of a motor and a transmission device. In this embodiment, the cutting edge 1431 is mounted at the end of the power component 142 and is moved by the power component 142. In other embodiments, the mating part 1433 may also be mounted at the end of the power component 142, and the power component 142 may move the mating part 1433 to achieve the cutting of the terminal strip 5 and the protective structure 53. In this embodiment, the cutting edge 1431 and the mating part 1433 cooperate with each other to achieve cutting using shearing force.

[0056] Feeding mechanism 15

[0057] Please see Figure 5 The diagram shows a perspective view of the feeding mechanism 15 provided in one embodiment of this application. The feeding mechanism 15 includes two supports 151 and a working module 150, which is supported by the two supports 151 and mounted above the cleaning device 16. Specifically, the supports 151 are provided with a guide rail 153 and a power component 154. The guide rail 153 extends along a sixth direction w6, which is parallel to the first direction w1. The working module 150 is mounted on the guide rail 153. In this embodiment, the working module 150 includes a first seat 155, which is mounted on the guide rail 153 and can be moved along the sixth direction w6 by the power component 154, thereby realizing the movement of the gripper module 152 within the working module 150 in the first dimension. The first seat 155 is also provided with a guide rail 1551 and a power component 1552. The guide rail 1551 extends along the seventh direction w7, which is perpendicular to the sixth direction w6. A second seat 156 is provided on the guide rail 1551. The second seat 156 can be moved along the seventh direction w7 by the power component 1552, thereby realizing the movement of the gripper module 152 in the second dimension. A third seat 157 and a power component 1561 are provided on the second seat 156. The third seat 157 is provided with a guide rail 1571 and a gripper module 152. The guide rail 1571 extends along the eighth direction w8, which is perpendicular to both the sixth direction w6 and the seventh direction w7, and parallel to the second direction w2. The gripper module 152 is driven by the power component 1561 to move along the guide rail 1571, thereby realizing the movement of the gripper module 152 in the third dimension, so that the two paired grippers of the gripper module 152 move closer or further away from each other, thereby realizing the gripping or putting down of the upper terminal 52 of the material section 54.

[0058] Specifically, in this embodiment, the first seat 155 has a starting position and an ending position in the sixth direction w6. The starting position corresponds to the rear track 223, and the ending position corresponds to the loading position within the cleaning device 16. To complete one loading action, firstly, the first seat 155 is either at the starting position or driven back to the starting position by the power component 154. Secondly, the second seat 256 is driven by the power component 1552 to descend along the seventh direction w7 to the position of the terminal 52. Thirdly, the gripper module... In the fourth step, the gripper 152 is driven by the power component 1561 to grip the terminal 52. In the fifth step, the second seat 256 is driven by the power component 1552 to move upward along the seventh direction w7. In the sixth step, the first seat 155 is driven by the power component 154 to reach the end position. In the seventh step, the second seat 256 is driven by the power component 1552 to descend along the seventh direction w7. At the beginning, the gripper of the gripper module 152 is driven by the power component 1561 to release the terminal 52. At this time, the material strip 51 connecting the terminal 52 is fixed on the fixing device 164 of the cleaning device 16. In this way, the gripper module 152 moves in three mutually perpendicular directions, completing the transfer of the material segment 54 and the terminal 52 on the material segment 54 from the rear track 223 to the cleaning device 16.

[0059] It is understood that in other embodiments, the order of the above-described feeding action steps can be changed as needed. Furthermore, in other embodiments, the power unit 1561 can also be mounted on the third base 157.

[0060] Cleaning device 16

[0061] Please see Figure 6 and Figure 7The figures shown are a perspective view and an exploded view of a cleaning device 16 provided in one embodiment of this application. The cleaning device 16 includes a tank 160 with a cleaning tank 165 for holding cleaning liquid. The cleaning device 16 also includes a transmission device 163 located within the cleaning tank 165 and a fixing device 164 fixed to the transmission device 163. The transmission device 163 is driven by a power component 166 located outside the tank 160, and reciprocates between the head end 161 and the tail end 162 of the cleaning device 16. In this embodiment, the transmission device 163 uses chain drive, and a fixing device 164 is fixed to the transmission device 163 at predetermined intervals along the second direction w2. The fixing device 164 moves with the movement of the transmission device 163. In this embodiment, the fixing device 164 is elongated, its length roughly matching the length of the material segment 54, and its length direction is the same as the first direction w1. The fixing device 164 is provided with a fixing part 1640. In this embodiment, the fixing part 1640 is a groove 1641, which is used to clamp the material segment 54. The opening of the groove 1641 is flared to facilitate the insertion of the material segment 54 by the feeding mechanism 15. In this embodiment, an ultrasonic device 167 is embedded below the bottom of the cleaning tank 165. In other embodiments, the ultrasonic device 167 can be located in any suitable position within the cleaning tank 165. The ultrasonic device 167 can also be replaced by other vibration devices.

[0062] In this embodiment, after the material segment 54 is fixed to the fixing device 164 at the feeding position by the feeding mechanism 15, the fixing device 164 is driven by the transmission device 163 to move forward a predetermined distance along the second direction w2. This predetermined distance is just enough to place the next fixing device 164 at the feeding position. The feeding mechanism 15 then fixes another material segment 54 to the next fixing device 164, and so on. As the transmission device 163 drives the fixing device 164 forward, the subsequent fixing devices 164 are successively loaded with the feeding segment 54. Since the material segment 54 is gradually loaded and gradually sent to the tail end 162, the terminals 52 on the material segment 54 are in contact with the cleaning liquid for a longer time during this process. In addition, the gradual forward movement of the transmission device 163 can also generate vibration. Therefore, in some cases, even without an additional vibration device, the required good cleaning effect can be achieved. In addition, by adopting the design of the transmission device 163 and the multi-row fixing device 164, after the first material segment 54 is sent to the tail end 162, the subsequent processing of the material segment 54 can be continuously realized without interruption. In this way, the processing effect of the pre-processing can be improved without affecting the production efficiency.

[0063] In this embodiment, the cleaning solution is alcohol.

[0064] In this embodiment, after the fixing device 164 and the material segment 54 on the fixing device 164 are transported to the tail end 162 at the upper end of the conveying device 163, the material segment 54 is picked up by the transfer device 17, and the unloaded fixing device 164 is returned to the head end 161 from the back end of the conveying device 163.

[0065] In this embodiment, the conveying device 163 is provided with brackets 1631 at both ends. The brackets 1631 are fixed to the bottom of the cleaning tank 165. The brackets 1631 are provided with rotating wheels 1632. The rotating wheels 1632 are connected to the power component 166 located outside the tank 160 via the transmission device 167 (only one gear is shown). The power component 166 drives the rotating wheel to rotate, thereby driving the conveying device 163 to convey the material segment 54 along the second direction w2.

[0066] Transfer device 17

[0067] Please see Figure 8 The figure shown is a perspective view of the transfer device 17 provided in one embodiment of this application. The transfer device 17 is supported by two or more legs and is disposed at the rear of the cleaning device 16, the cleaning liquid tank 18, the treatment liquid tank 19, and the drying device 20. In this embodiment, the structure of the working module 170 in the transfer device 17 is substantially the same as that of the working module 150 in the feeding mechanism 15, including a gripper module 171, multiple seats, and multiple power components. The working method of the working module 170 is also substantially the same as that of the working module 150, and will not be described again here. The difference is that in this embodiment, the movement of the working module 170 in the first dimension is achieved by the power component motor (not shown) driving the lead screw mechanism 175. In addition, in this embodiment, there are two working modules 170. One working module 170 is used to transfer the material segment 54 on the fixing device 164 at a predetermined position in the cleaning device 16 to the cleaning liquid tank 18, and then to the treatment liquid tank 19. Another operating module 170 is used to transfer the material section 54 in the processing liquid tank 19 to the drying device 20.

[0068] It is understood that in other embodiments, the number of operation modules 170 may also be one, with one operation module 170 transferring the material segment 54 on the fixing device 164 at a predetermined position in the cleaning device 16 to the cleaning liquid tank 18, then to the treatment liquid tank 19, and then to the drying device 20.

[0069] It is understandable that when there are two working modules 170, the two working modules 170 can be driven by different motors and different lead screw mechanisms 175. The tail ends of the two lead screw mechanisms 175 are connected, and the two motors are located at the head ends of the two lead screw mechanisms 175 respectively.

[0070] Cleaning fluid tank 18 and treatment fluid tank 19

[0071] Please see Figure 9 As shown, the cleaning fluid tank 18 is a tank structure, including a tank body 180, on which a cleaning tank 181 is formed for holding the cleaning fluid. A fixing device 182 is provided inside the cleaning tank 181. The structure of the fixing device 182 can be referred to as that of the fixing device 164 in the cleaning device 16, which has a fixing part 1820 for fixing the material section 54, and will not be described in detail here.

[0072] The treatment liquid tank 19 is a tank structure, including a tank body 190, on which a treatment trough 191 is formed for holding the treatment liquid. A fixing device 192 is provided inside the treatment trough 191. The structure of the fixing device 192 can be referred to as that of the fixing device 164 in the cleaning device 16, which has a fixing part 1920 for fixing the material section 54, and will not be described in detail here.

[0073] The length direction of both fixing device 182 and fixing device 192 is along the third direction w3. It can be understood that there can be one or more fixing devices 182 and fixing devices 192. When multiple fixing devices 182 are provided, the multiple fixing devices 182 are arranged along the second direction w2; when multiple fixing devices 192 are provided, the multiple fixing devices 192 are arranged along the second direction w2.

[0074] In this embodiment, the cleaning fluid is water, and the treatment fluid is glue. In other embodiments, the cleaning fluid, washing fluid, and treatment fluid can be provided as needed. Furthermore, the cleaning fluid tank 18 can be omitted depending on actual requirements.

[0075] Drying device 20

[0076] Please see Figure 10The diagram shown is a perspective view of the drying device in the embodiments of this application. The structure of the drying device 20 is largely the same as that of the cleaning device 16, also being a tank structure with a transfer device 203 and a fixing device 204 inside the tank 200. Its operation is also largely the same as that of the cleaning device 16, which can be summarized as follows: After the transfer device 17 transfers the material segment 54 from the treatment liquid tank 19 to the fixing device 204 located at a predetermined position (i.e., the loading position) in the drying device 200, the power component 205 and the transfer device 203 drive the fixing device 204 to move forward a predetermined distance along the fourth direction w4. This predetermined distance is just enough to place the next fixing device 204 at the loading position. The transfer device 17 then transfers another material segment 54 from the treatment liquid tank 19 to the next fixing device 204, and so on. As the conveying device 203 drives the fixing device 204 forward, subsequent fixing devices 204 are successively loaded with the feeding section 54. Since the feeding section 54 is loaded and gradually delivered to the tail end 202, the terminals 52 on the feeding section 54 remain for a longer period of time during this process, and the conveying section 54 itself agitates the air, which is beneficial for the drying or curing of the treatment liquid on the terminals 52. In addition, to further improve the drying or curing effect, the drying device 20 may further include an air supply device or a heating device. For example, air supply devices can be installed at different positions on the top of the tank 200.

[0077] Feeding mechanism 21

[0078] Please see Figure 11 The diagram shown is a perspective view of the feeding mechanism in one embodiment of this application. The feeding mechanism 21 is supported by a support 211 above the tail end 202 of the drying device 20. The support 211 is provided with a guide rail 213 and a power component 214. The guide rail 213 extends along the ninth direction w9, which is parallel to the first direction w1. The guide rail 213 is provided with a working module 210, which includes a gripper module 215, multiple seats, and multiple power components. The working module 210 has a starting position and an ending position in the ninth direction. The starting position corresponds to a preset position of the tail end 202 of the drying device 20, and the ending position is located outside the cabinet 11. The working module 210 grips the material segment 54 at the preset position inside the drying device 20 at the starting position, transports the material segment 54 to the ending position, and then puts it down, thus removing the material segment 54 whose upper terminal 52 has been processed from the automated terminal pre-processing machine 1. The structure of the operation module 210 is essentially the same as that of the operation module 150 in the feeding mechanism 15, and its operating principle is also essentially the same as that of the operation module 150. Therefore, the structure and operating principle of the operation module 210 will not be described in detail.

[0079] Please see Figure 12The diagram shown is a schematic diagram of a control system for controlling the operation of an automated terminal pre-processing device 1 provided in one embodiment of this application.

[0080] The control system 23 includes a controller 230, a memory 231, a display device 117, an input device 118, and multiple sensing devices 232 located at different positions. The controller 230 is connected to the memory 231, the display device 117, the input device 118, the sensing devices 232, and the alarm device 119 to input or read data and output results. Specifically, the memory 231 stores the control program and control parameters of the automated terminal preprocessing device 1. The controller 230 obtains the control program from the memory 231, runs the control program, and, in conjunction with the inputs from the sensing devices 232 and the input device 118, controls the automated terminal preprocessing device 1 to perform automated operations. The controller 230 may be a central processing unit or a microcontroller, etc.

[0081] The control system 23 also includes power components located at each working component. By controlling these power components, the control of each working component is achieved, enabling each working component to sequentially execute its corresponding task and collaboratively complete the pre-processing of the terminals. Specifically, the control system 23 includes power components located in the feeding mechanism 13, cutting device 14, loading mechanism 15, cleaning device 16, transfer device 17, drying device 20, unloading mechanism 21, and plasma cleaning device 22. For simplicity, [the following is omitted as it is not explicitly stated]. Figure 12 The document does not specify each power component in these mechanisms / devices, but uses "power components" as a general term for all power components in each mechanism / device. The number and function of power components in each mechanism / device can be found in the foregoing description.

[0082] In another embodiment, the control system 23 may further include a vibration device 233 and an air supply and / or heating device 234.

[0083] Please see Figure 13The diagram illustrates an example of the distribution of sensing devices in a control system 23 in one embodiment. In this embodiment, the control system 23 includes five sensing devices 232, namely a track-end sensing device 2321, a cleaning device-end sensing device 2322, a drying device-head sensing device 2323, a drying device-tail sensing device 2324, and a cutting device-end sensing device 2325. Specifically, the track-end sensor 2321 is disposed at the end of the rear track 223 along the first direction w1, and is used to sense whether a terminal 52 is present at that position; the cleaning device tail-end sensor 2322 is disposed at the position of the last fixing device 164 at the tail end 162 of the cleaning device 16, and is used to sense whether a terminal 52 is present at that position; the drying device head-end sensor 2323 is disposed at the position of the first fixing device 204 at the head end 201 of the drying device 20, and is used to sense whether a terminal 52 is present at that position; the drying device tail-end sensor 2324 is disposed at the position of the last fixing device 204 at the tail end 202 of the drying device 20, and is used to sense whether a terminal 52 is present at that position; and the cutting device end sensor 2325 is disposed between the first blade 14311 and the second blade 14312 of the cutting device, and is disposed close to the second blade 14312, to sense whether a terminal 52 is present at that position.

[0084] Please participate Figure 14-17 This is a schematic diagram of the process by which the control system 23 controls each working component of the automated terminal pretreatment device 1 in one embodiment.

[0085] Please see Figure 14 In operation 1501, the controller 230 controls the feeding mechanism 130 to pull the terminal strip 5 out of the tray 12.

[0086] In operation 1502, controller 230 controls cutting device 14 to cut material segment 54 from the pulled-out terminal strip 5.

[0087] In operation 1503, controller 230 controls feeding mechanism 15 to transfer the material segment 54 to cleaning device 16.

[0088] In operation 1504, controller 230 controls the cleaning device 16 to transfer the material segment 54 from the head end 161 of the cleaning device 16 to the tail end 162 of the cleaning device 16.

[0089] In operation 1505, controller 230 controls the transfer device 17 to transfer the material segment 54 from the cleaning device 16 to the treatment liquid tank 19 and from the treatment liquid tank 19 to the drying device 20.

[0090] In operation 1506, controller 230 controls the drying device 20 to transfer the material segment 54 from the head end 201 of the drying device 20 to the tail end 202 of the drying device 20.

[0091] In operation 1507, controller 230 controls feeding mechanism 21 to transfer the material segment 54 from the drying device 20 to the automated terminal pretreatment device 1.

[0092] The following details the control of the working components by the controller 230 at each stage of the operation.

[0093] Initialization and initial tasks

[0094] After the automated terminal pre-processing device 1 is powered on, an initialization operation is performed, controlling the operation modules of each operating component to reset (i.e., return to their initial state). Then, the controller 230 determines whether it has received a sensing signal from the cutting device end sensor 2325. In this embodiment, the cutting device end sensor 2321 generates a sensing signal and sends it to the controller 230 when it senses the presence of a terminal 52 near the second blade 14312. If no sensing signal is received from the cutting device end sensor 2325, the controller 230 controls the feeding mechanism 13 to continue feeding until a sensing signal is received from the cutting device end sensor 2321. After receiving the sensing signal from the cutting device end sensor 2321, the controller 230 controls the cutting device 14 to perform cutting and controls the operation module 134 of the feeding mechanism to reset. After cutting is completed, the controller 230 controls the cutting module 143 of the cutting device 14 to reset. Thus, the initialization and initial operation are completed.

[0095] Feeding, cutting, loading and cleaning control

[0096] Please see Figure 15 First, in operation 1601, the controller 230 determines whether it has received a sensing signal sent by the track end sensing device 2321. In this embodiment, the track end sensing device 2321 generates a sensing signal and sends it to the controller 230 when it senses the presence of a terminal 52 at the end of the rear track 223.

[0097] If no sensing signal is received from the track end sensor 2321, then in operation 1602, the controller 230 controls the feeding mechanism 13 to feed the material, and the process returns to operation 1601.

[0098] If a sensing signal is received from the track end sensor 2321, in operation 1603, the controller 230 controls the cutting device 14 to perform cutting and controls the operation module 134 of the feeding mechanism to reset.

[0099] In operation 1604, after waiting for a preset time, the controller 230 controls the cutting module 143 of the cutting device 14 to reset and controls the feeding mechanism 13 to grab the material segment 54 on the rear track 223 and transfer it to the cleaning device 16.

[0100] In operation 1605, the controller 230 controls the operation module 150 of the feeding mechanism 13 to reset and controls the cleaning device 16 to move forward a first preset distance, and the process returns to operation 1601.

[0101] In another embodiment, during operation 1605, the controller 230 further controls the vibration device 233 to vibrate for a preset time.

[0102] Processing and Drying Control

[0103] Please see Figure 16 In operation 1701, the controller 230 receives a sensing signal sent by the end sensor 2322 of the cleaning device.

[0104] In operation 1702, controller 230 controls the transfer device 17 to start and transfer the material segment 54 located on the last fixing device 164 at the tail end 162 of the cleaning device 16 to the cleaning liquid tank 18.

[0105] In operation 1703, controller 230 controls transfer device 17 to transfer material segment 54 located in cleaning liquid tank 18 to treatment liquid tank 19.

[0106] In operation 1704, controller 230 controls transfer device 17 to transfer the material segment 54 located in processing liquid tank 19 to drying device 20.

[0107] In operation 1705, the controller 230 receives a sensing signal sent by the head-end sensor 2323 of the drying unit.

[0108] In operation 1706, controller 230 resets the work module in transfer device 17 and moves drying device 20 forward a second preset distance. In this embodiment, the second preset distance is equal to the first preset distance. In other embodiments, the second preset distance may not be equal to the first preset distance.

[0109] In another embodiment, during operation 1706, the controller 230 also controls the air supply and / or heating device 234 to operate for a preset time.

[0110] In another embodiment, operations 1702 and 1703 can be replaced by controller 230 controlling the transfer device 17 to start and transfer the material segment 54 located on the last fixing device 164 at the tail end 162 of the cleaning device 16 to the processing liquid tank 19.

[0111] In another embodiment, during operation 1702, the controller 230 also simultaneously controls the plasma cleaning device 22 to start.

[0112] Material feeding control

[0113] Please see Figure 17 In operation 1801, the controller 230 receives a sensing signal sent by the sensor 2324 at the tail end of the drying unit.

[0114] In operation 1802, the controller 230 controls the feeding mechanism 21 to start, transferring the material segment 54 located on the last fixing device 204 at the tail end 202 of the drying device 20 to a predetermined position outside the cabinet 11.

[0115] In operation 1803, the controller 230 controls the operation module 210 in the unloading mechanism 21 to reset.

[0116] It is understood that in other embodiments, the number of the sensing devices 232 can be reduced. For example, the sensing device 2323 at the head of the drying device can be eliminated, and the controller 230 can control the drying device 20 to move forward a preset distance according to the timing relationship after controlling the transfer device 17 to transfer the material segment 54 to the drying device 20.

[0117] It is understood that in other embodiments, the number of the sensing devices 232 can be increased. For example, a sensing device can be set at the head end of the cleaning device 16 corresponding to the position of the first fixing device 164. The controller 232 controls the cleaning device 16 to move forward a preset distance according to the sensing signal of the sensing device. In addition, for example, a material shortage sensing device can also be set. The material shortage sensing device monitors the thickness of the terminal strip 5 in the material tray 12. When the terminal strip 5 is continuously pulled out and the thickness reaches a predetermined value, it sends a sensing signal to the controller 230. After receiving the sensing signal sent by the material shortage sensing device, the controller 230 controls the alarm device 119 to issue an alarm to remind the staff to prepare materials.

[0118] It is understandable that after receiving the shutdown signal sent by the input device 118, the controller 230 controls each working component to reset, and then the entire device stops operating.

[0119] Compared to existing technologies, the automated terminal pretreatment device 1 provided in this application embodiment uses an automated method to control the pretreatment of terminals, which improves efficiency compared to manual glue application. Furthermore, the cleaning device 16 and drying device 20 employ a combination of a transmission device and multiple rows of fixing devices, allowing the terminals 52 on the material section 54 to undergo a longer cleaning / drying period, achieving both improved pretreatment results and reduced production efficiency. Moreover, the main operating components of the automated terminal pretreatment device 1 are arranged in a U-shape, achieving a compact layout while avoiding complex motion designs for the loading mechanism 15, transfer device 17, and unloading device 21.

[0120] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
