Description

Technical Field

[0001] The utility model relates to the technical field of PCB board breaking, in particular to a board breaking device. Background Art

[0002] In the manufacturing process of the controller, it is often necessary to bend and cut the controller PCB board to fit a specific frame size. The traditional bend and cut method usually relies on manual operation and has the following problems and limitations:

[0003] 1. High labor cost of manual operation: The traditional method of breaking and cutting requires workers to manually break the boards first, and then use scissors or cutting tools to complete the cutting process. Therefore, it is necessary to hire specialized operators, which increases labor costs.

[0004] 2. The risk of cutting errors is relatively high: manual operation is easily affected by human factors, such as unstable holding of scissors, inaccurate operation, etc., which may cause damage to the PCB board, inaccurate cutting borders, and affect product quality.

[0005] 3. Low production efficiency: Due to the limitations of manual operation, the board breaking and cutting process usually takes a long time, resulting in low production efficiency and affecting the efficiency of the entire manufacturing process.

[0006] Although there are some automatic cutting devices in the prior art, they are often designed for specific types of products, such as paper, cloth, etc., and are not suitable for cutting controller PCB boards. In addition, these devices are too complex, expensive, or bulky, and cannot achieve the board breaking effect, making them unsuitable for large-scale application in controller production lines. Utility Model Content

[0007] In order to overcome the problems existing in the related technology, the purpose of the utility model is to provide a bending device, which realizes automatic bending and cutting of workpieces through the mutual cooperation of the bending assembly and the cutting assembly, thereby improving the efficiency and accuracy of workpiece bending.

[0008] A bending device comprises a bending assembly and a cutting assembly, wherein the cutting assembly is located at the side of the bending assembly, the workpiece has a first end and a second end arranged opposite to each other, the bending assembly comprises a first driving member, a fixing member and a clamping member, the fixing member is used to fix the first end of the workpiece, the clamping member is used to clamp the second end of the workpiece, and the first driving member can drive the clamping member to bend so that a bending crease appears on the workpiece;

[0009] The cutting assembly includes a second driving member and a cutter, and the second driving member can drive the cutter to move along the fold of the breaking plate to separate the two ends of the workpiece.

[0010] The present application can realize automatic board breaking and cutting, thereby improving the efficiency and accuracy of workpiece board breaking.

[0011] In a preferred technical solution of the utility model, the workpiece includes a front plate, a rear plate and a middle strip located between the front plate and the rear plate, and the connection between the middle strip and the front plate is provided with spaced hollows, and the connection between the middle strip and the rear plate is provided with spaced hollows.

[0012] In the process of workpiece production, in order to facilitate the separation of the front plate and the back plate, the position to be separated in the workpiece is set as a hollow connection, so that firstly the position of the board breaking and cutting can be clearly defined; secondly, the dimensional accuracy of the front plate and the back plate after separation can be clearly defined, and finally, the hollow connection position is slightly different from other positions in the connection relationship, which can improve the efficiency of board breaking. In the present application, when the board breaking component breaks the board, due to the presence of pores at the hollow connection position, the hardness is relatively small. The first driving member drives the rotation of the clamping member to form a board breaking mark that coincides with the hollow connection position. Afterwards, the cutting component cuts the board breaking fold at the hollow connection position. Also, due to the relatively small hardness at the hollow connection position, cutting can be easily achieved, thereby reducing the difficulty of cutting.

[0013] In a preferred technical solution of the utility model, it also includes a detection component, which is located on one side of the bending plate component. The detection component includes a photoelectric sensor, which is arranged toward the connection position between the front plate or the rear plate and the middle strip, and the photoelectric sensor is communicatively connected with the clamping member.

[0014] In the present application, the photoelectric sensor needs to detect the hollow connection positions at the front and rear ends of the middle strip in sequence. Specifically, a gap is provided at the hollow connection position. The photoelectric sensor can determine the position of the workpiece by detecting the gap, and then control the clamping part to clamp the two ends of the workpiece, thereby improving the accuracy of the board bending.

[0015] In a preferred technical solution of the present invention, the clamping member includes a first clamping arm, a second clamping arm and a third driving member, and the third driving member can drive the first clamping arm to move toward or away from the second clamping arm.

[0016] The clamping member in this embodiment has a simple structure and a simple driving method. Through the communication connection with the photoelectric sensor, the front plate or the middle strip can be clamped in time, which is beneficial to improving the clamping efficiency and the board breaking efficiency.

[0017] In a preferred technical solution of the present utility model, the first clamping arm and the second clamping arm are arranged parallel to the plane where the workpiece is located, and the first clamping arm and the second clamping arm are respectively located above and below the workpiece.

[0018] The workpiece can be transported on the transport line. When the workpiece is transported to the clamping position, the upper and lower surfaces of the workpiece are located exactly between the first clamping arm and the second clamping arm, which helps to clamp the front plate or the middle strip in the workpiece.

[0019] In a preferred technical solution of the utility model, it also includes a loading track and a unloading track, the clamping member is located between the loading track and the unloading track, and the fixing member is fixed in the loading track.

[0020] The bending assembly and the cutting assembly are located at the junction of the loading track and the unloading track, and a gap is provided between the loading track and the unloading track for fixing the bending assembly and the cutting assembly. The structure of the clamping part cooperates with the position structure of the loading track and the unloading track to help achieve smooth bending of the workpiece.

[0021] In a preferred technical solution of the utility model, the workpiece includes a front plate, a rear plate and a middle strip located between the front plate and the rear plate, and the length of the front plate and the rear plate is greater than the length of the middle strip; the minimum distance between the loading rail and the unloading rail is less than the length of the front plate or the rear plate.

[0022] When the front plate is clamped and bent by the clamping part, the end of the front plate away from the rear plate can extend into the unloading track. After the bending and cutting is completed, since the front plate part has abutted against the unloading track, the friction force of the unloading track on the front plate can make the front plate be unloaded smoothly from the unloading track.

[0023] In a preferred technical solution of the utility model, it also includes a recycling box, which is located below the gap between the loading track and the unloading track. A push rod is provided above the recycling box, and the push rod is used to push the middle strip into the recycling box.

[0024] The unloading track of the present application only needs to output the front plate and the rear plate, and the middle strip does not need to be output. However, the two ends of the middle strip are respectively connected to the front plate and the rear plate, so the middle strip also needs to be bent. When the front plate is bent and cut and then output by the unloading track, the photoelectric detector detects the hollow connection position again, which is the hollow connection position between the rear plate and the middle strip. At this time, one end of the middle strip is located between the first clamping arm and the second clamping arm, and the other end is still fixed in the rear plate, and the hollow connection position is suspended between the loading track and the clamping member. Similar to the above method, the bending and cutting of the middle strip and the rear plate are realized, and at the same time, the push rod is pushed out to push the middle strip into the recycling box; in the present application, the recycling box and the push rod cooperate with each other to realize the recycling of the middle strip.

[0025] In a preferred technical solution of the utility model, the clamping member includes a third driving member, a clamping arm and an intermediate conveyor belt. The third driving member can drive the clamping arm to move toward or away from the intermediate conveyor belt. The intermediate conveyor belt is located in the same plane as the loading track and the unloading track.

[0026] The clamping member in this embodiment has a simple structure and a simple driving method. Through the communication connection with the photoelectric sensor, the front plate or the middle strip can be clamped in time, which is beneficial to improving the clamping efficiency and the board breaking efficiency.

[0027] In a preferred technical solution of the utility model, the minimum distance between the loading track and the intermediate conveyor belt is less than the length of the front plate or the rear plate, and the minimum distance between the unloading track and the intermediate conveyor belt is less than the length of the front plate or the rear plate.

[0028] When the front plate is clamped and bent by the clamping member, the end of the front plate away from the rear plate can extend into the middle conveyor belt. After the bending and cutting is completed, since the front plate part is already in contact with the middle conveyor belt, the friction force of the middle conveyor belt on the front plate can smoothly transfer the front plate to the unloading track for unloading. At the same time, since the minimum distance between the unloading track and the middle conveyor belt is less than the length of the front plate or the rear plate, the front plate and the rear plate can be smoothly transferred when they are transferred along the middle conveyor belt.

[0029] The beneficial effects of the utility model are:

[0030] The present application provides a bending device, including a bending assembly and a cutting assembly, wherein the cutting assembly is located at the side of the bending assembly, and the workpiece has a first end and a second end arranged opposite to each other, which are used to bend the workpiece, wherein the workpiece refers to a workpiece formed by assembling two or more PCB boards, wherein the bending assembly is used to bend a single PCB board in the workpiece, so that a bending crease appears between the single PCB board and the workpiece, and the cutting assembly is used to cut and separate the bending crease to realize the bending operation of the workpiece.

[0044] Example 1

[0045] like Figure 1-Figure 6 As shown, a bending device provided in this embodiment includes a bending assembly and a cutting assembly, wherein the cutting assembly is located on the side of the bending assembly, and the workpiece has a first end and a second end arranged opposite to each other, and the bending assembly includes a first driving member, a fixing member and a clamping member 10, wherein the fixing member is used to fix the first end of the workpiece, and the clamping member 10 is used to clamp the second end of the workpiece, and the first driving member can drive the clamping member 10 to bend so that a bending crease appears on the workpiece; the cutting assembly includes a second driving member and a cutting knife 13, and the second driving member can drive the cutting knife 13 to move along the bending crease to achieve separation of the two ends of the workpiece.

[0046] The present application provides a bending device, including a bending assembly and a cutting assembly, wherein the cutting assembly is located at the side of the bending assembly, and the workpiece has a first end and a second end arranged opposite to each other, which are used to bend the workpiece, wherein the workpiece refers to a workpiece formed by assembling two or more PCB boards, wherein the bending assembly is used to bend a single PCB board in the workpiece, so that a bending crease appears between the single PCB board and the workpiece, and the cutting assembly is used to cut and separate the bending crease to realize the bending operation of the workpiece. Specifically, the bending assembly includes a first driving member, a fixing member and a clamping member 10, wherein the fixing member is used to fix one end of the workpiece, and the clamping member 10 is used to clamp the other end of the workpiece, and the first driving member drives the clamping member 10 and the clamping part to bend to form the bending crease; the cutting assembly includes a second driving member and a cutter 13, and the second driving member drives the cutter 13 to move along the bending crease to realize the separation of the clamping part and the fixed part, thereby realizing the bending operation of the workpiece; the present application can realize automatic bending and cutting, and improve the efficiency and accuracy of workpiece bending.

[0047] In the present application, the workpiece to be broken and cut can be an integral workpiece with a connecting gap. The connecting gap refers to the connection mark between two plates that need to be separated during the production process. The connection mark here refers to a hollow connection or light connection that is different from other positions.

[0048] like Figure 6 As shown in the figure, as a specific embodiment, the workpiece includes a front plate 16, a rear plate 17, and a middle bar 18 located between the front plate 16 and the rear plate 17, a first hole is provided between the middle bar 18 and the front plate 16, and a second hole is provided between the middle bar 18 and the rear plate 17. The first hole and the second hole are hollowed out to facilitate the separation of the front plate 16 and the rear plate 17.

[0049] As another specific embodiment, the workpiece is a controller PCB board, each of which integrates an even number of independent PCB sub-boards, and the connection between adjacent PCB sub-boards is provided with intervals hollowed out to the two ends of the middle strip 18. The board-breaking device in the present application is used to separate the multiple PCB sub-boards in each controller PCB board.

[0050] In the present application, the fixing member and the clamping member 10 are respectively used to fix the two ends of the workpiece, that is, the two parts of the workpiece to be separated, wherein the first driving member can drive the clamping member 10 and its fixed part to rotate and move. The rotational movement here refers to the rotation along the position to be separated. Only when the rotation occurs will the bending crease be generated.

[0051] In the present application, a hollow connection may be provided in the workpiece. When a hollow connection is provided, the first driving member drives the clamping member 10 and its fixed part to rotate along the hollow connection, and the fold formed at this time coincides with the hollow connection.

[0052] In the present application, the workpiece may not be provided with a hollow connection. When the hollow connection is not provided, the first driving member may drive the clamping member 10 and its fixed part to rotate along the end of the abutment position between the clamping member 10 and the workpiece, that is, the position of the plate breaking fold is determined by adjusting the position of the workpiece in the clamping member 10. The end of the abutment position between the clamping member 10 and the workpiece refers to the intersection position of the workpiece located inside the clamping member 10 and located outside the clamping member 10.

[0053] The cutter 13 in the cutting assembly of the present application can be a scissors handle, a grinding wheel or other appropriate tools, and is used to cut the folds of the breaking plate.

[0054] Example 2

[0055] like Figure 1-Figure 6As shown, a bending device provided in this embodiment includes a bending assembly and a cutting assembly, wherein the cutting assembly is located on the side of the bending assembly, and the workpiece has a first end and a second end arranged opposite to each other, and the bending assembly includes a first driving member, a fixing member and a clamping member 10, wherein the fixing member is used to fix the first end of the workpiece, and the clamping member 10 is used to clamp the second end of the workpiece, and the first driving member can drive the clamping member 10 to bend so that a bending crease appears on the workpiece; the cutting assembly includes a second driving member and a cutting knife 13, and the second driving member can drive the cutting knife 13 to move along the bending crease to achieve separation of the two ends of the workpiece.

[0056] This embodiment is described by taking the case where the workpiece includes two sub-boards to be separated as an example. When the workpiece includes multiple sub-boards, the separation method is similar.

[0057] Specifically, Figure 6 As shown, the workpiece includes a front plate 16, a rear plate 17 and a middle strip 18 located between the front plate 16 and the rear plate 17, wherein the connection between the middle strip 18 and the front plate 16 is provided with spaced hollows, and the connection between the middle strip 18 and the rear plate 17 is provided with spaced hollows.

[0058] In the process of workpiece production, in order to facilitate the separation of the front plate 16 and the back plate 17, the position to be separated in the workpiece is set as a hollow connection, so that firstly the position of the board breaking and cutting can be clearly defined; secondly, the dimensional accuracy of the front plate 16 and the back plate 17 after separation can be clearly defined, and finally, the hollow connection position is slightly different from other positions in the connection relationship, which can improve the efficiency of board breaking. In the present application, when the board breaking component breaks the board, due to the presence of pores at the hollow connection position, the hardness is relatively small. The first driving member drives the rotation of the clamping member 10 to form a board breaking mark that coincides with the hollow connection position. Afterwards, the cutting component cuts the board breaking fold at the hollow connection position. Also, due to the relatively small hardness at the hollow connection position, cutting can be easily achieved, thereby reducing the difficulty of cutting.

[0059] The bending device of the present application also includes a detection component, which is located on one side of the bending component. The detection component includes a photoelectric sensor, which is set toward the connection position between the front plate 16 or the rear plate 17 and the middle strip 18, and the photoelectric sensor is communicatively connected with the clamping member 10.

[0060] The photoelectric sensor can detect the hollow connection position. When the photoelectric sensor detects the hollow connection position, it can be determined that the workpiece is transmitted into the bending plate assembly. At this time, after the clamping member 10 receives the workpiece in place signal, it controls the clamping member 10 to fix the front plate 16, and controls the fixing member to fix the rear plate 17 and the middle strip 18, thereby achieving the fixation of both ends of the workpiece. The present application can set the photoelectric sensor on the side of the clamping member 10, so that when the photoelectric sensor detects the hollow connection position, the clamping member 10 can just clamp the front plate 16 or the middle strip 18.

[0061] In this embodiment, the same workpiece needs to be broken twice. The first time is to break and cut along the hollow connection position between the front plate 16 and the middle strip 18. At this time, the middle strip 18 and the back plate 17 are a whole, and the front plate 16 is a whole, and the two wholes are separated. The second time is to break and cut along the hollow connection position between the middle strip 18 and the back plate 17. At this time, the middle strip 18 and the back plate 17 are separated, thereby realizing the separation between the front plate 16, the middle strip 18 and the back plate 17. After separation, the middle strip 18 can be directly recycled, and the front plate 16 and the back plate 17 need to be transferred to the unloading position for collection and standby.

[0062] In the present application, the photoelectric sensor needs to detect the hollow connection positions at the front and rear ends of the middle strip 18 in sequence. Specifically, a gap is provided at the hollow connection position. The photoelectric sensor can determine the position of the workpiece by detecting the gap, and then control the clamping member 10 to clamp the two ends of the workpiece, thereby improving the accuracy of the board bending.

[0063] In actual operation, the photoelectric sensor can be set on the side of the workpiece in the direction of transmission, or above or below the workpiece in the direction of transmission, so as to detect the pores at the hollow connection position. For example, when the outermost side of the hollow connection position is provided with pores, the photoelectric sensor can be set on the side of the workpiece. When there are no pores at the outermost side of the hollow connection position, and the pores are evenly distributed on the inner side, the photoelectric sensor can be set above and below the workpiece.

[0064] The workpiece is transported along a specific transmission track in the bending device. In the present application, the bending assembly and the cutting assembly are arranged in the transmission track. The workpiece-shaped bending board is cut during the workpiece transmission process to ensure that the workpiece is a unified whole when entering the bending device and is cut into the front plate 16, the middle strip 18 and the rear plate 17 when output from the bending device. Figure 6 shown.

[0065] As a specific embodiment, the clamping member 10 includes a first clamping arm 101 , a second clamping arm 102 and a third driving member, and the third driving member can drive the first clamping arm 101 to move toward or away from the second clamping arm 102 .

[0066] like Figure 1-Figure 5 As shown, the first clamping arm 101 is fixed at the bottom of the clamping slide rail 103, the second clamping arm 102 is slidably connected to the clamping slide rail 103, and the third driving member is connected to the second clamping arm 102 and can drive the second clamping arm 102 to move toward or away from the first clamping arm 101. Figure 4 As shown, when the workpiece is not transferred to the position of the clamping member 10, that is, the photoelectric sensor does not detect the hollow connection position, the second clamping arm 102 is away from the first clamping arm 101. Figure 5 As shown, when the photoelectric sensor detects the hollow connection position, at this time, the front plate 16 or the middle strip 18 is located between the first clamping arm 101 and the second clamping arm 102, and the third driving member drives the second clamping arm 102 to move toward the first clamping arm 101 until the front plate 16 or the middle strip 18 is clamped; then the first driving member drives the clamping member 10 and the clamped part to rotate, and due to the low hardness of the hollow connection, a board bending crease is generated at the hollow connection. In this embodiment, the clamping member 10 has a simple structure and a simple driving method. Through the communication connection with the photoelectric sensor, the front plate 16 or the middle strip 18 can be clamped in time, which is conducive to improving the clamping efficiency and the board bending efficiency.

[0067] As a specific embodiment, the first clamping arm 101 and the second clamping arm 102 are arranged parallel to the plane where the workpiece is located, and the first clamping arm 101 and the second clamping arm 102 are respectively located above and below the workpiece.

[0068] The workpiece can be transported on the transmission line. When the workpiece is transported to the position of the clamping member 10, the upper and lower surfaces of the workpiece are located exactly between the first clamping arm 101 and the second clamping arm 102, which helps to clamp the front plate 16 or the middle bar 18 in the workpiece.

[0069] like Figure 1-Figure 3 As shown, the present application further includes a loading track 11 and a unloading track 12 , the clamping member 10 is located between the loading track 11 and the unloading track 12 , and the fixing member is fixed in the loading track 11 .

[0070] The loading track 11 and the unloading track 12 together form a transmission component for the workpiece. In the loading track 11, the workpiece is a unified whole, and what is output through the unloading track 12 is a separate front plate 16, a rear plate 17 and a middle strip 18. The plate bending assembly and the cutting assembly are located at the intersection of the loading track 11 and the unloading track 12, and a gap is provided between the loading track 11 and the unloading track 12 for fixing the plate bending assembly and the cutting assembly. The structure of the clamping member 10 cooperates with the position structure of the loading track 11 and the unloading track 12, which helps to achieve smooth plate bending of the workpiece. In the present application, the front plate 16 refers to the sub-plate that first arrives at the position of the clamping member 10 along the transmission direction of the loading track 11, and the rear plate 17 refers to the sub-plate that arrives at the position of the clamping member 10 later along the transmission direction of the loading track 11.

[0071] In the present application, the photoelectric sensor is arranged on the side of the feeding track 11 or the side of the clamping member 10, the clamping member 10 is arranged between the feeding track 11 and the unloading track 12, and the fixing member is arranged in the feeding track 11. When the photoelectric sensor detects the hollow connection position, it means that the workpiece is transferred to the clamping range of the clamping member 10. At this time, the third driving member drives the second clamping arm 102 to move toward the first clamping arm 101 until the first clamping arm 101 and the second clamping arm 102 clamp the front plate 16. At the same time, the fixing member clamps and fixes the rear plate 17 and the middle bar 18. At this time, only the hollow connection position of the front plate 16 and the middle bar 18 is exposed outside the clamping member 10 and the fixing member. The first driving member drives the clamping member 10 and the front plate 16 to rotate. Due to the low hardness of the hollow connection position, a bending fold coincident with the hollow connection position is formed.

[0072] In the present application, the length of the front plate 16 and the rear plate 17 is greater than the length of the middle bar 18; the minimum distance between the loading track 11 and the unloading track 12 is less than the length of the front plate 16 or the rear plate 17. The length refers to the dimension along the transmission direction of the loading track 11 and the unloading track 12.

[0073] That is to say, when the front plate 16 is clamped and bent by the clamping member 10, the end of the front plate 16 away from the rear plate 17 can extend into the unloading track 12. When the unloading and cutting is completed, since part of the front plate 16 has been in contact with the unloading track 12, the friction force of the unloading track 12 on the front plate 16 can enable the front plate 16 to be unloaded smoothly from the unloading track 12.

[0074] In this embodiment, the minimum distance between the loading rail 11 and the first clamping arm 101 is greater than the length of the middle bar 18. At the same time, a recycling box is provided below the gap between the loading rail 11 and the unloading rail 12, and a push rod is provided above the recycling box, and the push rod is used to push the middle bar 18 into the recycling box.

[0075] The unloading track 12 of the present application only needs to output the front plate 16 and the rear plate 17, and the middle strip 18 does not need to be output. However, the two ends of the middle strip 18 are connected to the front plate 16 and the rear plate 17 respectively, so the middle strip 18 also needs to be bent. When the front plate 16 is bent and cut and then output by the unloading track 12, the photoelectric detector detects the hollow connection position again, which is the hollow connection position between the rear plate 17 and the middle strip 18. At this time, one end of the middle strip 18 is located between the first clamping arm 101 and the second clamping arm 102, and the other end is still fixed in the rear plate 17, and the hollow connection position is suspended between the loading track 11 and the clamping member 10. Similar to the above method, the middle strip 18 and the rear plate 17 are bent and cut, and the push rod is pushed out to push the middle strip 18 into the recycling box; in the present application, the recycling box and the push rod cooperate with each other to realize the recycling of the middle strip 18.

[0076] Example 3

[0077] like Figure 1-Figure 8 As shown, a bending device provided in this embodiment includes a bending assembly and a cutting assembly, wherein the cutting assembly is located on the side of the bending assembly, and the workpiece has a first end and a second end arranged opposite to each other, and the bending assembly includes a first driving member, a fixing member and a clamping member 10, wherein the fixing member is used to fix the first end of the workpiece, and the clamping member 10 is used to clamp the second end of the workpiece, and the first driving member can drive the clamping member 10 to bend so that a bending crease appears on the workpiece; the cutting assembly includes a second driving member and a cutting knife 13, and the second driving member can drive the cutting knife 13 to move along the bending crease to achieve separation of the two ends of the workpiece.

[0078] like Figure 6 As shown, the workpiece includes a front plate 16, a rear plate 17 and a middle strip 18 located between the front plate 16 and the rear plate 17, wherein the connection between the middle strip 18 and the front plate 16 is provided with spaced hollows, and the connection between the middle strip 18 and the rear plate 17 is provided with spaced hollows.

[0079] The bending device of the present application also includes a detection component, which is located on one side of the bending component. The detection component includes a photoelectric sensor, which is set toward the connection position between the front plate 16 or the rear plate 17 and the middle strip 18, and the photoelectric sensor is communicatively connected with the clamping member 10.

[0080] like Figure 1-Figure 3 As shown, the present application further includes a loading track 11 and a unloading track 12 , the clamping member 10 is located between the loading track 11 and the unloading track 12 , and the fixing member is fixed in the loading track 11 .

[0081] In the present application, the loading track 11 and the unloading track 12 are both parallel and symmetrically arranged, which are used to transport the two sides of the workpiece, thereby ensuring the stable advancement of the workpiece.

[0082] The cutting assembly in the present application further includes a cutting slide rail 15, in which the cutter 13 is located, and the second driving member can drive the cutter 13 to move along the cutting slide rail 15. The cutting slide rail 15 extends in the same direction as the hollow connection position in the workpiece.

[0083] The difference from Example 2 is:

[0084] In this embodiment, the clamping member 10 includes a third driving member, a clamping arm 104 and an intermediate transmission belt 105. The third driving member can drive the clamping arm 104 to move toward or away from the intermediate transmission belt 105. The intermediate transmission belt 105 is located in the same plane as the loading track 11 and the unloading track 12.

[0085] The intermediate conveyor belt 105 is located between the loading track 11 and the unloading track 12, and is used to transfer the front plate 16 after the board is broken and cut to the unloading track 12, so as to facilitate the smooth transfer of the front plate 16 and the rear plate 17 between the loading track 11 and the unloading track 12. That is, the loading track 11, the intermediate conveyor belt 105 and the unloading track 12 are located in the same plane, and together form a workpiece transfer device before and after the board is broken.

[0086] Among them, Figure 7 and Figure 8 As shown, one end of the clamp arm 104 is hinged in the hinge column 106, and the other end extends above the horizontal conveyor belt. When the third driving member drives the clamp arm 104 to rotate close to the horizontal conveyor belt, the workpiece can be clamped. Figure 7 When the third driving member drives the clamping arm 104 to rotate away from the horizontal conveyor belt, the workpiece can be released, such as Figure 8 shown.

[0087] In the present application, there are two intermediate conveyor belts 105 and two corresponding clamping members 10, which are used to clamp the two ends of the workpiece, the front plate 16 or the intermediate strip 18 respectively.

[0088] The hinge column 106 is fixed to the side of the intermediate conveyor 105 close to the loading track 11, one end of the clamp arm 104 is hinged to the hinge column 106, and the other end extends above the intermediate conveyor 105. Specifically, the width of the hinged end of the clamp arm 104 is smaller, and the width of the side located above the intermediate conveyor 105 is larger. The width refers to the dimension in the direction parallel to the connecting line of the two intermediate conveyor belts 105, so that the clamp arm 104 can rotate around the hinge and clamp the workpiece.

[0089] In this embodiment, the clamping member 10 has a simple structure and a simple driving method. Through the communication connection with the photoelectric sensor, it can clamp the front plate 16 or the middle strip 18 in time, which is beneficial to improving the clamping efficiency and the board breaking efficiency.

[0090] In the present application, the photoelectric sensor is arranged on the side of the clamping member 10, the clamping member 10 is arranged between the loading track 11 and the unloading track 12, and the fixing member is arranged in the loading track 11. When the photoelectric sensor detects the hollow connection position, it means that the workpiece is transferred to the clamping range of the clamping member 10. At this time, the third driving member drives the clamping arm 104 to rotate to abut against the front plate 16 on the intermediate transmission belt 105, so as to clamp the front plate 16. At the same time, the fixing member clamps and fixes the rear plate 17 and the middle bar 18. At this time, only the hollow connection position of the front plate 16 and the middle bar 18 is exposed outside the clamping member 10 and the fixing member. The first driving member drives the clamping member 10 and the front plate 16 to rotate. Due to the low hardness of the hollow connection position, a bending fold coincident with the hollow connection position is formed.

[0091] In the present application, the minimum distance between the loading track 11 and the intermediate conveyor belt 105 is less than the length of the front plate 16 or the rear plate 17 , and the minimum distance between the unloading track 12 and the intermediate conveyor belt 105 is less than the length of the front plate 16 or the rear plate 17 .

[0092] When the front plate 16 is clamped and bent by the clamping member 10, the end of the front plate 16 away from the rear plate 17 can extend into the intermediate conveyor belt 105. After the bending and cutting is completed, since the front plate 16 part is already in contact with the intermediate conveyor belt 105, the friction force of the intermediate conveyor belt 105 on the front plate 16 can smoothly transfer the front plate 16 to the unloading track 12 for unloading. At the same time, since the minimum distance between the unloading track 12 and the intermediate conveyor belt 105 is less than the length of the front plate 16 or the rear plate 17, when the front plate 16 or the rear plate 17 is transferred along the intermediate conveyor belt 105, a smooth transition between the front plate 16 and the rear plate 17 can be achieved.

[0093] A recovery box is provided below the gap between the loading track 11 and the unloading track 12 , and a push rod is provided above the recovery box, and the push rod is used to push the middle bar 18 into the recovery box.

[0094] The unloading track 12 of this application only needs to output the front plate 16 and the rear plate 17, and the middle strip 18 does not need to be output. However, the two ends of the middle strip 18 are connected to the front plate 16 and the rear plate 17 respectively, so the middle strip 18 also needs to be bent. When the front plate 16 is bent and cut, it is output by the intermediate conveyor belt 105 and the unloading track 12. When the photoelectric detector detects the hollow connection position again, it is the hollow connection position between the rear plate 17 and the middle strip 18. At this time, one end of the middle strip 18 is located in the clamp 10, and the other end is still fixed in the rear plate 17, and the hollow connection position is suspended between the loading track 11 and the clamp 10. Similar to the above method, the middle strip 18 and the rear plate 17 are bent and cut, and the push rod is pushed out to push the middle strip 18 into the recycling box; in this application, the recycling box and the push rod cooperate with each other to achieve the recycling of the middle strip 18.

[0095] Example 4

[0096] The difference from Example 2 or Example 3 is that: no push rod is provided, but the first driving member drives the rotation of the clamping member 10 and the middle bar 18, so that the middle bar 18 falls into the recycling box under the action of gravity.

[0097] Specifically, when the clamping member 10 clamps the middle bar 18 and the fixing member fixes the rear plate 17, the first driving member drives the clamping member 10 to rotate upward. Since the hollow connection between the middle bar 18 and the rear plate 17 is relatively hard, a plate breaking fold is formed. After the second driving member drives the cutter 13 to cut along the plate breaking fold, the middle bar 18 and the rear plate 17 are separated. At this time, the clamping member 10 and the middle bar 18 remain in the position after the upward rotation, that is, the middle bar 18 is in a tilted state, but is fixed by the clamping member 10. At this time, the third driving member drives the clamping member 10 to loosen, and the middle bar 18 can fall into the recycling box under the action of gravity.
