[0004] The present application provides the following technical solutions:

[0005] In a first aspect, the present application provides a feeding module, which comprises a conveying assembly, a first limiting assembly and a second limiting assembly. The conveying assembly is used to convey the circuit boards. The conveying assembly has a feeding station and a buffer station on a conveying path. The buffer station and the feeding station are sequentially arranged in the conveying direction of the conveying assembly. The conveying path is arranged along a first preset direction. The first limiting assembly is movably arranged, so that the first limiting assembly has a limiting state and a non-limiting state.

[0006] In the limiting state, the first limiting assembly is located on the conveying path, and the first limiting assembly is located between the feeding station and the buffer station. In the non-limiting state, the first limiting assembly is located outside the conveying path. The second limiting assembly is located on the conveying path, and the second limiting assembly is located at one end of the feeding station away from the buffer station.

[0007] In some embodiments of the first aspect, the conveying assembly comprises a pair of conveying chains arranged side by side. The conveying chain has a chain link. The chain link connecting shaft has an extension end. The chain has a conveying section. The extension end is located between the pair of conveying chains. The circuit board is located between the chain links of the pair of conveying chains. The circuit board is located above the extension end of the conveying section. The side of the circuit board and the extension end of the conveying section close to each other abuts.

[0008] In some embodiments of the first aspect, the circuit board is at least partially located between links of the transport segments of a pair of transport chains.

[0009] In some embodiments of the first aspect, the conveying assembly further includes at least one chain spacing adjuster, wherein at least one of the conveying chains is connected to the chain spacing adjuster, the chain spacing adjuster being used to adjust the distance between a pair of the conveying chains.

[0010] In some embodiments of the first aspect, the chain spacing adjuster includes a first drive unit and at least one lead screw, wherein one of the conveyor chains is a fixed conveyor chain and the other of the conveyor chains is a movable conveyor chain, the first drive unit is connected to the at least one lead screw to drive the lead screw to rotate, and the lead screw is threadedly connected to a sleeve on the movable conveyor chain.

[0011] In some embodiments of the first aspect, the number of lead screws is at least two, all of which are spaced apart in the conveying direction of the conveyor chain, and the first drive unit is used to drive all of the lead screws to rotate.

[0012] In some embodiments of the first aspect, the chain spacing adjuster further includes a slide rail, the slide rail being arranged parallel to the axial direction of the lead screw, the fixed conveyor chain and the movable conveyor chain being spaced apart in the length direction of the slide rail, the fixed conveyor chain being fixedly arranged, and the movable conveyor chain being slidably arranged on the slide rail.

[0013] In some embodiments of the first aspect, the loading module further includes a lifting assembly located below the loading station, the lifting assembly being used to lift the circuit board located at the loading station.

[0014] In some embodiments of the first aspect, the lifting assembly includes a second driving part and an elastic suction cup, the elastic suction cup being used to adsorb a circuit board, the elastic suction cup being connected to the second driving part, the second driving part being used to drive the elastic suction cup to move along a second preset direction, the second preset direction being perpendicular to the first preset direction.

[0015] Secondly, this application also provides a board splitting machine, which includes a material handling drive assembly and a feeding module as described in any of the above embodiments.

[0016] The embodiments of this application have the following advantages:

[0017] The application provides a feeding module. A conveying path extends along a first preset direction and is divided into a feeding station and a buffer station. The buffer station is used for temporarily storing circuit boards conveyed from a conveying assembly. One or more circuit boards can be accommodated, and a gap is maintained between adjacent circuit boards to facilitate operation of a first limiting assembly. The feeding station is used for placing a single circuit board (or a plurality of parallel circuit boards in a case where docking precision is low) to be processed, so that a taking assembly can accurately perform a taking operation. The first limiting assembly can be switched between a limiting state and a non-limiting state. When located on the conveying path, the first limiting assembly blocks subsequent circuit boards from advancing to the feeding station, so that the circuit boards are kept in the buffer station. When moved out of the conveying path, the first limiting assembly allows the frontmost circuit board to continue to advance to the feeding station. A second limiting assembly serves as a fixed barrier and is located at an end of the feeding station away from the buffer station, so as to prevent the circuit board from leaving the feeding station too early and ensure that the circuit board is accurately positioned to facilitate operation of the taking assembly.

[0018] Obviously, when the circuit boards are conveyed to the buffer station by the conveying assembly, if the feeding station is idle, the first limiting assembly is switched to the non-limiting state to allow the frontmost circuit board to enter the feeding station. If the feeding station is occupied, the first limiting assembly is maintained in the limiting state to prevent other circuit boards from advancing. After the taking assembly is ready, the first limiting assembly is switched back to the non-limiting state to release the next circuit board; at the same time, the second limiting assembly ensures that the current circuit board is kept at a correct position until the circuit board is taken away.

[0019] Therefore, due to the presence of the first limiting assembly, the conveying assembly does not need to frequently start and stop to adjust the position of the circuit board, thereby reducing wear of mechanical components. Moreover, the continuous conveying mechanism and the accurately controlled limiting system improve the processing speed and accuracy of the circuit board. Reduced damage to equipment means less maintenance demand and reduced long-term operating costs. Furthermore, through optimized logistics management and accurate positioning, the stability and product quality of the entire production process are ensured, and the processing efficiency is improved.

[0032] In the related art, a board splitter is a special-purpose device for dividing a large printed circuit board into a plurality of independent small circuit boards. The board splitter has a feeding assembly. Generally, the feeding assembly is used to feed the circuit boards one by one to a feeding station, the circuit boards at the feeding station are taken away by a taking assembly, and then the above-mentioned actions are repeated. However, this way needs to frequently start and stop the feeding assembly, which is harmful and has low processing efficiency. It should be noted that the above-mentioned feeding one by one is to avoid the interference of the taking action of the taking assembly caused by the contact of adjacent circuit boards. Generally, the taking assembly uses a vacuum adsorption method to take the material.

[0033] As shown in Figure 1 To solve the above technical problems, the present application provides a feeding module 100, which comprises a conveying assembly, a first limiting assembly 160 and a second limiting assembly 200. The conveying assembly is used to convey circuit boards. The conveying assembly has a feeding station 150 and a buffer station 140 on the conveying path. The buffer station 140 and the feeding station 150 are sequentially arranged in the conveying direction of the conveying assembly. The conveying path is arranged along the first preset direction. The first limiting assembly 160 is movably arranged, so that the first limiting assembly 160 has a limiting state and a non-limiting state.

[0034] In the limiting state, the first limiting assembly 160 is located on the conveying path, and the first limiting assembly 160 is located between the feeding station 150 and the buffer station 140. In the non-limiting state, the first limiting assembly 160 is located outside the conveying path. The second limiting assembly 200 is located on the conveying path, and the second limiting assembly 200 is located at one end of the feeding station 150 away from the buffer station 140.

[0035] In these embodiments, the present application provides an improved feeding module 100 for the automatic feeding process of circuit boards in a board separating machine. The feeding module 100 aims to solve the problems of equipment damage and low processing efficiency caused by frequent start-stop in the traditional feeding process.

[0036] In which, the conveying assembly is responsible for conveying the circuit board from one position to another position. Obviously, the conveying assembly has a clear conveying path, and the conveying action of the conveying assembly makes the circuit board move along the conveying path.

[0037] Exemplarily, in this embodiment, the conveying path is a straight line. Of course, in other embodiments, the conveying path can also be set as an arc line or a broken line, etc.

[0038] And, the conveying path is divided into a feeding station 150 and a buffer station 140, and is arranged along a first preset direction. That is to say, if the first preset direction is a straight line direction, then the conveying path is a straight line. If the first preset direction is an arc direction, then the conveying path is an arc line.

[0039] Exemplarily, the first limiting assembly 160 can adopt an electric, pneumatic or other type of driving mode, and select a suitable driving device according to the specific application scene, such as a servo motor, an air cylinder, etc., to realize high-precision movement control. Of course, the moving direction of the first limiting assembly 160 can be set as a vertical direction, a horizontal direction or an arc direction, etc.

[0040] Exemplarily, the first limiting assembly 160 includes a first limiting block, and the feeding assembly further includes a limiting driving assembly 190, the first limiting block and the limiting driving assembly 190 are connected, and the limiting driving assembly 190 is used to drive the first limiting block to rise and fall. The limiting driving assembly 190 can be an electric push rod, an air cylinder or a hydraulic cylinder, etc.

[0041] Exemplarily, the second limiting assembly 200 includes a second limiting block, and the position of the second limiting block is fixedly arranged, and then can abut against one end of the circuit board located in the feeding station 150 and away from the buffer station 140, so as to accurately position the circuit board.

[0042] In this application, the conveying path is taken as an example of being set as a horizontal straight line.

[0043] The first limiting assembly 160 controls the movement of the circuit board between the feeding station 150 and the buffer station 140. Then, by controlling the movement of the first limiting assembly 160, the first limiting assembly 160 has at least two working modes.

[0044] Working mode: can be switched between the limiting state (located on the conveying path) and the non-limiting state (moved out of the conveying path). When in the limiting state, the subsequent circuit board is prevented from advancing to the feeding station 150, that is, the subsequent circuit board is blocked from moving to the feeding station 150 without stopping the feeding assembly, so that the subsequent circuit board stays in the buffer station 140; when in the non-limiting state, the circuit board in the buffer station 140 is allowed to continue to move forward to move to the feeding station 150.

[0045] It should be noted that, in order to ensure the precise docking of the position between the material taking assembly and the circuit board in the feeding station 150, the feeding station 150 is used to accommodate one circuit board. Of course, for the case where the position docking precision requirement is low, the feeding station 150 can be used to accommodate multiple parallel circuit boards, and a gap is maintained between adjacent circuit boards.

[0046] Similarly, the buffer station 140 can also be used to accommodate at least one circuit board. For example, the buffer station 140 is used to accommodate 1, 2, 3, 4, or 5, etc. Further, a gap is maintained between adjacent circuit boards, thereby facilitating the first limiting assembly 160 to enter and exit between adjacent circuit boards, forming a limit.

[0047] The second limiting assembly 200 serves as a barrier at the front end of the feeding station 150, ensuring that the circuit board is accurately stopped at the feeding station 150, avoiding the circuit board from moving out of the feeding station 150. It is beneficial for the precise docking between the material taking assembly and the circuit board placed in the feeding station 150. Specifically, the second limiting assembly 200 is fixed to the end of the feeding station 150 away from the buffer station 140, that is, at the end of the feeding station 150, and the buffer station 140 is close to the starting end of the feeding station 150.

[0048] In addition, the working principle is as follows: when the circuit board reaches the buffer station 140 through the conveying assembly, if the feeding station 150 is temporarily unavailable, for example, because the previous circuit board is being taken away, the first limiting assembly 160 will switch to the limiting state to prevent the subsequent circuit board from advancing.

[0049] Once the material taking assembly is ready, the first limiting assembly 160 switches to the non-limiting state, allowing the frontmost circuit board to smoothly enter the feeding station 150, while the second limiting assembly 200 ensures that the circuit board is accurately stopped at the feeding station 150 for further processing.

[0050] Therefore, this feeding mechanism allows the conveying assembly to continue to run without frequent start and stop, thereby reducing mechanical damage and improving overall processing efficiency. That is, in this way, the feeding module 100 provided by the embodiment of the present application can effectively improve the working efficiency of the board separating machine and reduce equipment wear and tear.

[0051] AsFigure 1 and Figure 2 As shown in FIG. 11, in some embodiments, the conveying assembly includes a pair of conveying chains arranged side by side, each conveying chain having a chain with chain links connected by chain connecting shafts 122 having extended ends, the chain having a conveying section, the extended ends being located between the pair of conveying chains, the circuit board being located between the chains of the pair of conveying chains, the circuit board being located above the extended ends of the conveying section, the circuit board and the extended ends of the conveying section abutting each other on a side close to each other.

[0052] In these embodiments, to further optimize the functionality and operational convenience of the feeding module 100, a pair of conveying chains arranged side by side is designed. This design not only ensures that the circuit board can be smoothly and accurately conveyed to the designated position, but also realizes effective support and guidance of the circuit board through the special structure of the chain.

[0053] Among them, a pair of conveying chains are arranged side by side, i.e. two conveying chains are arranged in parallel to form a stable conveying channel for conveying the circuit board along a first predetermined direction (i.e. the conveying path).

[0054] The chain of each conveying chain is composed of a plurality of chain links 121, and each chain link 121 is connected by a chain connecting shaft 122. The chain connecting shaft 122 has an extended end, and these extended ends are located between the pair of conveying chains. A part of the chain serves as a conveying section for directly contacting and supporting the circuit board. Exemplarily, the upper side of the extended end and the lower side of the circuit board abut and support each other.

[0055] The circuit board is located between the chains of the pair of conveying chains and above the extended ends of the conveying section. The circuit board and the extended ends of the conveying section abut each other on a side close to each other, ensuring that the circuit board remains stable during the conveying process. Moreover, the circuit board is located between the chain links 121 of the conveying section of the chains of the pair of conveying chains, and the chain links 121 form side plates to limit and guide the movement of the circuit board, i.e. to limit the movement direction of the circuit board and prevent the circuit board from falling off the conveying chain.

[0056] For ease of understanding, the conveying process is provided as follows:

[0057] When the conveying chain is started, the conveying section of the chain moves along the conveying path, driving the chain links 121 and the chain connecting shafts 122 to move together. The extended ends of the chain connecting shafts 122 are located between the pair of conveying chains, forming a stable support platform to ensure that the circuit board does not fall or tilt during the conveying process. The circuit board maintains an abutting state with the extended ends of the chain connecting shafts and the chain links 121 of the conveying section, ensuring that it is always in the correct position during the conveying process.

[0058] Therefore, the circuit board is supported by the extended end of the chain link connecting shaft 122, ensuring that the circuit board remains stable throughout the entire conveying process, reducing the risk of damage caused by shaking. Moreover, the limiting of the chain link 121 allows the circuit board to be accurately conveyed to the feeding station 150 and the buffer station 140, improving the accuracy of subsequent material taking and board separating operations. Furthermore, through the improvement of the chain, both supporting the circuit board and limiting the circuit board can be achieved without the need for additional structural components, thereby reducing costs.

[0059] For example, different types of chains such as roller chains, plate chains, etc. can be selected according to specific application scenarios to meet different load and speed requirements.

[0060] The conveying chain can be driven by electricity, gas or other types of drive, and appropriate driving devices such as servo motors, reducers, etc. can be selected according to specific application scenarios to achieve high-precision conveying control.

[0061] As shown in Figure 1 In some embodiments, the circuit board is at least partially located between the chain links 121 of the conveying sections of a pair of conveying chains.

[0062] In these embodiments, the chain links 121 on both sides of the circuit board are used for limiting, which can reduce the amount of deviation or shaking of the circuit board during conveying.

[0063] That is, the circuit board can be accurately conveyed to the feeding station 150 and the buffer station 140, improving the accuracy of subsequent material taking and board separating operations.

[0064] For example, a part of the chain links 121 of the conveying section and the circuit board remain in contact. That is, the chain links 121 of the conveying section and the corresponding side edges of the circuit board abut.

[0065] In some embodiments, the conveying assembly further comprises at least one chain spacing adjusting member 110, wherein the at least one conveying chain is connected with the chain spacing adjusting member 110, and the chain spacing adjusting member 110 is used to adjust the distance between a pair of conveying chains.

[0066] In these embodiments, the conveying assembly is further optimized to accommodate circuit boards of different sizes. Specifically, the conveying assembly comprises at least one chain spacing adjusting member 110 connected to at least one conveying chain. The main function of the chain spacing adjusting member 110 is to adjust the distance between a pair of conveying chains, thereby ensuring that circuit boards of different widths or specifications can be stably and accurately handled.

[0067] The two conveying chains are arranged side by side to form a stable conveying channel. Each conveying chain is composed of a plurality of chain links 121, and each chain link 121 is connected by a chain link connecting shaft 122.

[0068] The chain distance adjusting member 110 is used to adjust the distance between a pair of conveying chains. At least one conveying chain is connected with the chain distance adjusting member 110, and the position of the conveying chain can be changed by the chain distance adjusting member 110, so as to adjust the distance between the two conveying chains.

[0069] For example, the chain distance adjusting member 110 can be a manual or automatic adjusting device, such as a screw rod, a pneumatic cylinder, or an electric push rod, etc., and the appropriate adjusting mode is selected according to the specific application scenario.

[0070] When it is necessary to adjust the distance between a pair of conveying chains, the operator can manually or automatically adjust through the chain distance adjusting member 110. The chain distance adjusting member 110 drives the corresponding conveying chain to move, changes the distance between the two conveying chains, and adapts to circuit boards of different widths.

[0071] After adjusting the distance, the conveying chain is started, and the chain moves along the predetermined path, driving the chain link 121 and the connecting shaft on it to move together.

[0072] Obviously, through the chain distance adjusting member 110, the conveying assembly can flexibly adjust the distance between a pair of conveying chains, adapt to circuit boards of different sizes and widths, and improve the versatility and flexibility of the equipment. The flexible adjusting capability reduces the preparation time when replacing circuit boards of different sizes, and improves the overall production line efficiency.

[0073] The automatic chain distance adjusting member 110 (such as using a pneumatic cylinder or an electric push rod) reduces manual intervention, reduces the work burden of the operator, and improves the operation convenience.

[0074] For example, a pair of conveying chains are arranged on the slide rail 130, one of which is a fixed conveying chain 120 and is fixedly arranged, and the other of which is a movable conveying chain 180 and is slidably arranged. The chain distance adjusting member 110 is connected with the movable conveying chain 180 to drive the movable conveying chain 180 to move along the slide rail 130, so as to move away from or close to the fixed conveying chain 120.

[0075] For example, the chain distance adjusting member 110 includes a driving motor and a lead screw 111. The driving motor is arranged on the fixed conveying chain 120. The main shaft of the driving motor is connected with the lead screw 111 to drive the lead screw 111 to rotate. The lead screw is threadedly connected with a screw sleeve on the movable conveying chain 180. The lead screw and the slide rail 130 are arranged in parallel.

[0076] As shown in FIG. 1, Figure 1 For example, the chain distance adjusting member 110 includes a first driving part 112 and at least one lead screw 111. One of the conveying chains is a fixed conveying chain 120, and the other of the conveying chains is a movable conveying chain 180. The first driving part 112 is connected with the at least one lead screw 111 to drive the lead screw 111 to rotate. The lead screw is threadedly connected with a screw sleeve on the movable conveying chain 180.

[0077] In these embodiments, the fixed conveying chain 120 and the movable conveying chain 180 are arranged axially spaced apart from each other. The first driving part 112 drives the screw rod 111 to rotate, so as to drive the movable conveying chain 180 to move axially along the screw rod 111 by virtue of the threaded connection between the screw rod 111 and the screw nut, thereby adjusting the distance between the fixed conveying chain 120 and the movable conveying chain 180.

[0078] For example, the first driving part 112 is arranged on the frame of the fixed conveying chain 120, the screw nut is arranged on the frame of the movable conveying chain 180, and the first driving part 112 is a driving motor. The main shaft of the driving motor is connected with the screw rod 111 to drive the screw rod 111 to rotate. The screw rod is arranged in parallel with the slide rail 130, and the frame of the movable conveying chain 180 is slidingly arranged on the slide rail 130.

[0079] For example, the number of screw rods 111 is one, two, three, four, five, six, seven, or the like.

[0080] As shown in Figure 1 some embodiments, the number of screw rods 111 is at least two, and all the screw rods are arranged axially spaced apart from each other in the conveying direction of the conveying chain. The first driving part 112 is configured to drive all the screw rods to rotate.

[0081] In these embodiments, by arranging a plurality of screw rods 111 in the conveying direction and driving them by the same first driving part 112, the two ends of the two conveying chains can be synchronously moved close to or away from each other, and the distance between the two conveying chains can be accurately controlled.

[0082] For example, the first driving part 112 includes a driving motor and a transmission mechanism 113. The driving motor is connected with all the screw rods 111 through the transmission mechanism 113, so as to simultaneously drive all the screw rods 111. The transmission mechanism 113 is a belt transmission mechanism 113. Of course, in other embodiments, the transmission mechanism 113 can also be a gear transmission mechanism 113 or a chain transmission mechanism 113, or the like.

[0083] As shown in Figure 1 some embodiments, the chain distance adjusting member 110 further includes a slide rail 130. The length direction of the slide rail 130 is arranged in parallel with the axial direction of the screw rod. The fixed conveying chain 120 and the movable conveying chain 180 are arranged axially spaced apart from each other along the length direction of the slide rail 130. The fixed conveying chain 120 is fixedly arranged, and the movable conveying chain 180 is slidingly arranged on the slide rail 130.

[0084] In these embodiments, the slide rail 130 ensures that the movable conveying chain 180 can move smoothly and precisely. The length direction of the slide rail 130 is parallel to the axial direction of the lead screw, providing a stable linear motion path so that the movable conveying chain 180 can slide along the slide rail 130 within a set range. The fixed conveying chain 120 is fixedly arranged and does not move with the change of the chain pitch, serving as a stable reference point of the conveying assembly. The movable conveying chain 180 is arranged to slide through a sliding block or similar device on the slide rail 130, and its position relative to the fixed conveying chain 120 can be adjusted as needed to change the distance between the two.

[0085] When it is necessary to adjust the distance between a pair of conveying chains, the operator first loosens any locking mechanism that may exist. By rotating the lead screw (or other forms of driving devices), the distance of the movable conveying chain 180 moving along the slide rail 130 can be precisely controlled. The movable conveying chain 180 slides along the length direction of the slide rail 130, thereby changing the distance with the fixed conveying chain 120. Once the desired distance is reached, the operator can fix the movable conveying chain 180 in the new position through the tightening mechanism (such as a locking nut), ensuring that no accidental displacement occurs during work.

[0086] Due to the very smooth linear motion path provided by the slide rail 130, combined with the precise displacement control provided by the lead screw, the entire process can achieve high-precision distance adjustment. Obviously, the movement direction of the movable conveying chain 180 can be further limited, and the synchronization of the movement of the two ends of the movable conveying chain 180 can be provided.

[0087] As shown in FIGS. Figure 1 and Figure 3 In some embodiments, the feeding module 100 further comprises a lifting assembly 170, which is located below the feeding station 150 and is used to lift the circuit board located in the feeding station 150.

[0088] In these embodiments, the feeding module 100 is further optimized by adding the lifting assembly 170 to lift the circuit board located in the feeding station 150.

[0089] The lifting assembly 170 is located below the feeding station 150 and between the two conveying chains, at the end of the conveying path, i.e., the position where the circuit board finally arrives and waits to be taken away. The lifting assembly 170 is used to lift the circuit board located in the feeding station 150, so that it is separated from the conveying assembly and reaches a height or position that is more conducive to the operation of the taking-out assembly.

[0090] When the circuit board is moved to the loading station 150 by the conveying assembly, it is temporarily stopped on the conveying chain and waits for further processing. Once it is confirmed that the circuit board has been correctly positioned and the taking assembly is ready, the lifting assembly 170 is activated. The lifting assembly 170 is usually composed of a driving mechanism such as a pneumatic cylinder, hydraulic device or electric push rod, which can provide enough force to lift the circuit board smoothly. During the lifting process, the lifting assembly 170 ensures that the circuit board remains in a horizontal state, avoiding tilting or overturning, thereby ensuring the accuracy of subsequent operations. After the circuit board is lifted to a predetermined height, the taking assembly (such as a mechanical hand, vacuum suction cup, etc.) can more easily access the circuit board for grabbing or suction operations.

[0091] After the taking is completed, the lifting assembly 170 will automatically descend and reset, preparing for the next circuit board. To prevent misoperation, the lifting assembly 170 is equipped with sensors or other detection devices to confirm that the circuit board has been successfully taken away before performing the reset action.

[0092] Obviously, by lifting the circuit board to an optimal height, the interference between the taking assembly and the conveying assembly is reduced, and the docking accuracy between the two is improved. The taking step is simplified, the processing time of a single circuit board is shortened, and the production efficiency of the entire board separator is improved. Since the circuit board no longer directly contacts the conveying chain during the taking process, the risk of surface scratching or other physical damage is reduced.

[0093] Exemplarily, the lifting assembly 170 can be an electric push rod, pneumatic cylinder, hydraulic cylinder, etc.

[0094] As shown in FIG. 1, some embodiments include a lifting assembly 170 for lifting the circuit board to a predetermined height, so that the taking assembly can easily access the circuit board for taking. Figure 3 In some embodiments, the lifting assembly 170 includes a second driving part 172 and an elastic suction cup 171 for adsorbing the circuit board, the elastic suction cup 171 and the second driving part 172 are connected, and the second driving part 172 is used to drive the elastic suction cup 171 to move along a second preset direction, and the second preset direction is perpendicular to the first preset direction.

[0095] In these embodiments, the lifting assembly 170 includes the second driving part 172 and the elastic suction cup 171 to achieve more precise and stable processing of the circuit board.

[0096] The second driving part 172 provides power to drive the elastic suction cup 171 to move along the second preset direction. The second preset direction is perpendicular to the first preset direction (i.e., the direction of the conveying path), ensuring that the lifting action and the conveying action are independent of each other and do not interfere with each other. Exemplarily, the second driving part 172 can be pneumatic, hydraulic or electric, etc. in different forms, depending on the design requirements and application scenarios of the device.

[0097] The elastic suction cup 171 is used to adsorb the circuit board located in the feeding station 150, ensuring its stability during lifting. Made of elastic material, it has good flexibility and sealing performance, and can form uniform adsorption force on the surface of circuit boards of different shapes and sizes. It is directly connected with the second driving part 172 and receives power input from the driving part to achieve precise position control.

[0098] When the circuit board reaches the feeding station 150 through the conveying assembly, the elastic suction cup 171 is in standby state, ready to adsorb the circuit board. The second driving part 172 starts to move the elastic suction cup 171 to the appropriate position above the circuit board. After the elastic suction cup 171 contacts the circuit board, it firmly grips the surface of the circuit board using vacuum or other adsorption mechanisms, ensuring that it will not slide or tilt during subsequent lifting. After adsorption is complete, the second driving part 172 continues to work, lifting the elastic suction cup 171 and the circuit board it adsorbs upward along the second preset direction (perpendicular to the conveying path). The lifting process is smooth and controllable, avoiding any physical damage to the circuit board. After the circuit board is lifted to the predetermined height, the material taking assembly (such as a mechanical hand, a vacuum suction cup, etc.) can more easily access the circuit board for grabbing or further processing. During this process, the elastic suction cup 171 continues to maintain the adsorption state until the material taking assembly completely takes over. After the material taking is completed, the elastic suction cup 171 releases the circuit board and is lowered back by the second driving part 172, ready for the next circuit board.

[0099] Therefore, through the precise control of the second driving part 172, the elastic suction cup 171 can accurately reach the required position, improving the accuracy of circuit board adsorption and lifting. The stable adsorption force provided by the elastic suction cup 171 ensures the stability of the circuit board during the entire processing process, reducing the risk of surface scratches or other damage.
