[0035] See also Figure 1 and Figure 2 The utility model provides an automatic board breaking and blanking mechanism for automatically breaking a PCB board, comprising: a board breaking device 1 and a positioning device 2, the board breaking device 1 is arranged on one side of the positioning device 2, the positioning device 2 is provided with a plurality of positioning grooves 21 for accommodating the PCB board, the board breaking device 1 is provided with a clamp assembly 11 for grabbing the PCB board and placing the PCB board into the positioning groove 21 and a board breaking piece 12 for breaking the board, and the board breaking piece 12 is connected to the clamp assembly 11.

[0036] The utility model fixes the PCB board by setting the positioning groove 21, and bends the PCB board by the bend member 12, thereby realizing automatic bend of the PCB board, greatly reducing the labor intensity of employees and improving the overall production efficiency. At the same time, no manual operation is required, avoiding product quality problems caused by the instability of manual operation, thereby effectively improving the quality of the product.

[0037] In this embodiment, the shape of the positioning groove 21 is the same as that of the PCB board, so that the PCB board can be firmly placed in the positioning groove 21 to prevent movement or misalignment during the board bending process. This not only improves the accuracy of board bending, but also further improves production efficiency and product quality.

[0038] In this embodiment, please refer to Figure 3 and Figure 4 The clamp assembly 11 includes: a clamp bracket 111, a plurality of clamp driving members 112 and a plurality of clamp plates 113, one end of the clamp bracket 111 is connected to the breaking plate member 12, and the plurality of clamp driving members 112 are installed at the other end of the clamp bracket 111;

[0039] One side of one of the clamping plates 113 is transmission-connected to at least one clamp driving member 112, and the other side is spaced apart from one side of another clamping plate 113;

[0040] The other side of the other clamping plate 113 is drivingly connected to at least one clamp driving member 112 .

[0041] When the PCB board needs to be grasped, at least two clamp driving members 112 respectively drive the two clamp plates 113 to approach each other to clamp the PCB board between the two clamp plates 113. When the grasped PCB board needs to be placed, only two clamp driving members 112 are required to respectively drive the two clamp plates 113 to move away from each other.

[0042] Furthermore, one side of one of the clamping plates 113 is transmission-connected to the plurality of clamp driving members 112 , and the other side is spaced apart from one side of another clamping plate 113 ;

[0043] The other side of the other clamping plate 113 is drivingly connected to the plurality of clamp driving members 112 .

[0044] The multiple clamp driving members 112 can achieve a stronger driving force on the clamping plate 113, thereby enhancing the clamping force on the PCB. This enhanced clamping force can effectively prevent the PCB from moving during the board bending process, ensuring the accuracy and stability of the board bending; the multiple clamp driving members 112 can act on different positions of the clamping plate 113 respectively, thereby achieving a uniform distribution of the clamping force. In this way, the PCB board can be prevented from being subjected to excessive or uneven force locally during the clamping process, reducing the risk of deformation of the PCB board.

[0045] In this embodiment, a connecting plate 114 (such as Figure 4 As shown in the figure, the connecting plate 114 and the clamping plate 113 are fixedly connected by screws, and the connecting plate 114 is arranged between the two clamping plates 113; the existence of the connecting plate 114 makes the clamp assembly 11 more flexible and adjustable, and by adjusting the position and number of the connecting plates 114, it can meet the clamping requirements of workpieces of different shapes, sizes and weights. This flexibility makes the clamp assembly 11 more versatile and applicable to a wider range of production scenarios.

[0046] The clamping plate 113 may be made of AL6061 to ensure the firmness of the clamping structure, and the connecting plate 114 may be made of polyurethane to reduce the friction loss with the PCB board.

[0047] In this embodiment, a guide block (not shown in the figure) is provided on the clamp 113, and a guide rail (not shown in the figure) is provided on the clamp bracket 111; or, a guide rail is provided on the clamp 113, and a guide block is provided on the clamp bracket 111, and the guide block is slidably provided on the guide rail.

[0048] The sliding of the guide block on the guide rail ensures the stability of the clamping plate 113 during the movement, and avoids the shaking or deviation of the clamping plate 113. This stability ensures the uniform distribution and continuous action of the clamping force, and can prevent the PCB board from shifting or deforming during the board bending process.

[0049] In this embodiment, please refer to Figure 5 The clamp bracket 111 includes: a fixed plate 1111, a plurality of connecting rods 1112 and a support plate 1113, one side of the fixed plate 1111 is connected to the bending plate 12, one end of a plurality of connecting rods 1112 are connected to the other side of the fixed plate 1111, the other ends of a plurality of connecting rods 1112 are connected to one side of the support plate 1113, and a plurality of clamp driving components 112 are installed on the other side of the support plate 1113.

[0050] The fixing plate 1111 is the base of the fixture bracket 111 and is connected to the breaking plate 12, ensuring the overall stability of the fixture bracket 111. One end of the connecting rod 1112 is connected to the fixing plate 1111, and the other end is connected to the supporting plate 1113, forming a solid frame structure, which enhances the rigidity and load-bearing capacity of the fixture bracket 111; the design of several connecting rods 1112 allows the fixture bracket 111 to be adjusted and changed as needed. By changing the number, length or connection method of the connecting rods 1112, it can adapt to workpieces of different sizes and shapes, thereby realizing flexible configuration and customization of the fixture assembly 11.

[0051] In this embodiment, the fixing plate 1111 can be made of 45# steel to ensure the stability of the entire clamp bracket 111 , and the connecting rod 1112 and the supporting plate 1113 can be made of AL6061 to ensure the reliability of the entire clamp bracket 111 .

[0052] In this embodiment, please refer to Figure 1 The breaking plate 12 includes: a base 121 and a mechanical arm 122 , one end of the mechanical arm 122 is connected to the base 121 , and the other end of the mechanical arm 122 is connected to the clamp assembly 11 .

[0053] In the overall workflow, the board breaking member 12 can automatically complete multiple steps such as grabbing the PCB board, inserting it into the positioning slot 21, breaking the board, and placing it in the turnover box through the precise control of the mechanical arm 122. This not only greatly improves production efficiency and reduces labor costs, but also ensures product consistency and quality stability.

[0054] Specifically, the panel breaking member 12 may be a four-axis robot, a five-axis robot, a six-axis robot or other robots. The panel breaking member 12 using a robot can adapt to various application scenarios.

[0055] In this embodiment, please refer to Figure 1-6 , and also includes: a bending plate bracket 3, a positioning device 2 is arranged on the top surface of the bending plate bracket 3; the positioning device 2 includes a shell 22, a positioning groove 21 is arranged on a side of the shell 22 away from the bending plate bracket 3, and a through hole 221 is arranged on the other side of the shell 22 corresponding to the positioning groove 21, and a material receiving box 4 is arranged below the bending plate bracket 3, and the material receiving box 4 is arranged corresponding to the through hole 221, and the through hole 221 is connected to the positioning groove 21.

[0056] After the breaking piece 12 breaks the PCB board, the broken PCB board residues will fall from the positioning groove 21 under the action of their own gravity, and finally fall into the material receiving box 4 through the through hole 221. In this way, the PCB board residues can be automatically collected without manual picking or cleaning, which greatly improves the production efficiency and reduces the labor intensity of the operator.

[0057] Among them, the shell 22 can be made of anti-static bakelite. The anti-static properties of anti-static bakelite enable the shell 22 to maintain stable performance in various environments. The material receiving box 4 can be made of plastic. Plastic can buffer the impact force of PCB board residues on the material receiving box 4, thereby reducing the damage to the material receiving box 4 caused by the falling of PCB board residues.

[0058] In this embodiment, a positioning drive member 222 and a blocking bracket 223 (such as Figure 6 As shown), the positioning driving member 222 is transmission-connected with the blocking bracket 223 to drive the blocking bracket 223 to block the bottom of the positioning groove 21.

[0059] Before the board-breaking member 12 breaks the PCB board, the positioning drive member 222 drives the blocking bracket 223 to block the bottom of the positioning groove 21 to ensure that the PCB board will not fall accidentally during the board-breaking process. When the board is broken, the positioning drive member 222 drives the blocking bracket 223 to move away again, so that the bottom of the positioning groove 21 is exposed again, so that the PCB board residues can fall smoothly into the receiving box 4.

[0060] For further information, see Figure 6 The blocking bracket 223 includes: a bottom plate 2231 and a blocking plate 2232 , the bottom plate 2231 and the blocking plate 2232 are fixedly connected to form an L shape, and the bottom plate 2231 is drivingly connected to the positioning drive member 222 .

[0061] Specifically, if the blocking plate 2232 is connected to the upper end of the bottom plate 2231, the PCB board only contacts the blocking plate 2232 when inserted into the positioning groove 21. In this way, the bottom plate 2231 and the blocking plate 2232 are fixedly connected and form an L shape, so that the blocking bracket 223 blocks the bottom of the positioning groove 21. Even if the force of the positioning drive member 222 is too large, the blocking bracket 223 can adapt to it through a certain deformation, so that the damage to the housing 22 and the blocking bracket 223 caused by the excessive force of the positioning drive member 222 can be reduced.

[0062] If the sealing plate 2232 is fixedly connected to the upper end of the bottom plate 2231, the PCB board can abut against the sealing plate 2232 and the bottom plate 2231 when it is inserted into the positioning groove 21. The size of the sealing plate 2232 and the bottom plate 2231 can be adjusted according to the size specifications of the PCB board, so that when the sealing plate 2232 abuts against the inner wall of the shell 22, the distance between the bottom plate 2231 and the inner wall of the shell 22 is the same as the width of the PCB board. In this way, the PCB board can be better clamped to prevent the PCB board from moving during the process of bending the board.

[0063] In one embodiment, the blocking plate 2232 and the bottom plate 2231 are slidably connected. When the blocking plate 2232 abuts against the inner wall of the shell 22, the bottom plate 2231 can continue to move to abut against the PCB board under the action of the positioning drive member 222, thereby effectively clamping the PCB board. The slidable connection between the blocking plate 2232 and the bottom plate 2231 enables the blocking bracket 223 to adapt to PCB boards of different sizes.

[0064] Furthermore, a slider and a slide rail may be provided between the blocking bracket 223 and the shell 22 to ensure the stability of the blocking bracket 223 during movement, thereby avoiding shaking or deviation of the blocking bracket 223 .

[0065] In this embodiment, a plurality of positioning devices 2 are provided, and the plurality of positioning devices 2 are arranged side by side. The plurality of positioning slots 21 are located on the same horizontal line, and the clamp assembly 11 covers all the positioning slots 21 .

[0066] The provision of multiple positioning devices 2 enables the board breaking member 12 to simultaneously break multiple PCB boards, thereby greatly improving the board breaking efficiency.

[0067] In this embodiment, the positioning device 2 is provided with a sensing member 5 (such as Figure 2 As shown in FIG. 1 , the sensing element 5 can be a photoelectric sensor, and the sensing element 5 can automatically detect the arrival of the PCB board without manual intervention or additional operation. This greatly improves the automation level of the production line, reduces errors and delays caused by human factors, and improves overall production efficiency.

[0068] In this embodiment, the fixture driving member 112 and the positioning driving member 222 can adopt driving devices such as electric push rods, electric cylinders, linear motor drivers or cylinders.

[0069] The working process of the entire automatic plate breaking and blanking mechanism is as follows:

[0070] 1. The board breaking member 12 drives the clamp assembly 11 through an external signal to clamp the PCB board in the tray (or turnover box), and then moves the coordinate point to a fixed position just above the positioning device 2, and then controls the robot program to vertically insert the PCB board into the positioning groove 21.

[0071] 2. After the induction element 5 on the positioning device 2 senses the incoming PCB board, it transmits a signal to the internal positioning drive element 222 to control the positioning drive element 222 to push the blocking bracket 223 to the bottom of the positioning groove 21 to block the positioning groove 21.

[0072] 3. After the fixture assembly 11 inserts the PCB board into the positioning groove 21, the board breaking member 12 drives the fixture assembly 11 to perform the board breaking action according to the signal instruction and the PLC program.

[0073] The main board-bending action is to calculate the corresponding matching coordinate points and parameters according to the board-bending direction and movement trajectory of the PCB board using software logic algorithms and geometric analysis, and then the board-bending component 12 drives the clamp assembly 11 to perform the board-bending action according to the coordinate points.

[0074] 4. When the board breaking process is completed, the board breaking member 12 will drive the clamp assembly 11 and the PCB board to rise, and put the completed PCB boards into a new turnover box next to it, waiting for the next process to pick them up manually. The positioning drive member 222 in the housing 22 will then perform the return action according to the signal of the sensor 5. At this time, the broken PCB board residue will fall from the positioning groove 21 and fall into the receiving box below.

[0075] The above operations are then repeated in sequence until the material receiving box is full, and then the materials can be recycled and disposed of in a unified manner.

[0076] Under the original operation mode, the efficiency of manual processing of a single PCB board product is low. The entire process, including manual picking, board breaking, and waste material removal and recycling, takes about 8 seconds. The automatic board breaking and blanking mechanism of this embodiment realizes the automatic clamping, board breaking and blanking of PCB boards, and it only takes about 6 seconds to process each product. In addition, the mechanism also supports double-station operation, that is, the board breaking operation of two products can be performed at the same time. By comparison, the mechanism has improved the overall efficiency by about 110%. Taking daily output as the evaluation standard, the output of a single shift of 8 hours in the original operation mode is about 3,500 pieces, while after adopting the new device, the single-shift output can be increased to about 3,850 pieces, and the efficiency is significantly improved.

[0077] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same or similar parts between the various embodiments can be referred to each other. It should be pointed out that for ordinary technicians in this technical field, the utility model can also be improved and modified without departing from the principle of the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.

[0078] It should also be noted that, in this specification, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive.

In the absence of more restrictions, the elements defined by the sentence "including a..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
