Description

TECHNICAL FIELD

[0001] The application relates to the production and processing field of connecting pieces, in particular to a pin suction device and a connecting piece pin equipment. BACKGROUND

[0002] The connector is a component that electronic engineering technicians often contact. Its role is very simple: in the circuit, it builds a bridge between the broken place or the isolated circuit, so that the current flows, and the circuit realizes the predetermined function. The connector is an indispensable part of electronic equipment. You will always find one or more connectors along the current flow path.

[0003] The pin jack terminal of the connector is matched with the glue shell. The terminal is divided into male terminal and female terminal (also called male terminal and female terminal). The male terminal is matched with the glue shell, inserted into the female terminal matched glue shell, and forms a closed loop to make the current or electric signal smooth. Related technologies such as Chinese patent application "strip-shaped connector", application number: CN201821849618.5, disclose a glue shell, a plurality of pins arranged in the glue shell, a welding piece, one end of the pin has a welding part exposed outside the glue shell, the other end of the pin has a plug-in part inserted into the glue shell, and the middle part of the pin has a limiting protruding part. A limiting groove is arranged in the glue shell corresponding to the limiting protruding part, the limiting protruding part is clamped in the limiting groove and constitutes the clamping connection of the glue shell and the pin, and a clamping hole is arranged on both sides of the glue shell. One welding piece is arranged in each of the two clamping holes. The welding piece includes a clamping part inserted into the clamping hole and a welding fixed part. The basic shape of the welding fixed part is L-shaped, and the welding fixed part has a first welding surface and a second welding surface exposed outside the glue shell.

[0004] In the field of mechanical automation, because the number of pins arranged on a connector is large, the manual welding method is obviously extremely low in efficiency. Therefore, in this field, automatic assembly equipment has also appeared. Related technologies such as Chinese patent application "electrical connector pin system", application number: CN202010326452.4, disclose that it includes a processing track and a feeding unit, a pin unit, a plug unit, a detection unit and a packaging unit arranged in sequence on the processing track. A plurality of ion fans are arranged on the processing track. Through the joint action of the pin unit, the plug unit, the detection unit and the packaging unit, the workpiece on the processing track can be automatically fed, pinched, plugged, detected and packaged, thereby greatly improving the efficiency of connector production and the quality of the produced connector.

[0005] It is undeniable that the automation equipment in the prior art can greatly improve the production and processing efficiency of products. However, the pin to be assembled in the present application is L-shaped, but the pin belongs to a soft and flexible metal sheet structure. Therefore, if the design of the pin suction device is unreasonable, the pin part will be deformed, resulting in defective pins, which will affect the yield of the subsequent connector. SUMMARY

[0006] The technical problem to be solved by the present application is to provide a pin suction device and a connector pin device, which optimizes the structure of the pin suction device, so that the pin structure is not damaged when clamping the pin, and the working precision of the pin inserted into the insert block is improved.

[0007] The technical solution adopted by the present application is: a pin suction device, comprising a mechanical arm group and a suction nozzle assembly, the suction nozzle assembly comprises a fixed seat, at least two air nozzles are installed on the fixed seat, at least one air nozzle is vertically arranged, at least one air nozzle is horizontally arranged, a gas channel is arranged in the fixed seat, the gas channel is connected with the air pump and the air nozzle, the air pump works, and the air nozzle will adsorb the L-shaped pin, and the air nozzles on the fixed seat act on two different surfaces of the L-shaped pin.

[0008] Compared with the prior art, the present application has the advantages that the soft and flexible pin is first considered, the pin is grasped by abandoning the commonly used jaw structure in the mechanical field, and the jaw grasps the power device, which is a hard mechanical action, and hard touches the pin, which easily causes the deformation of the pin. The present application adopts the structure design of air pump combined with air nozzle, which can well solve the problem of easy deformation of the pin. Specifically, at least two air nozzles are installed on the fixed seat, so as to realize the suction of the L-shaped pin. The surface on the outer side of the L-shaped pin is composed of two planes. At least one air nozzle is vertically arranged, and at least one air nozzle is horizontally arranged, so that the air nozzles on the different surfaces of the outer side of the L-shaped pin can adsorb the pin. The L-shaped pin is adsorbed from two surfaces to ensure the reliability and stability of the pin suction.

[0009] In some embodiments of the present application, the suction end of the air nozzle is made of a horn-shaped structure made of elastic material. The air nozzle with the horn-shaped suction end has a certain range of elastic deformation, which can better fit the surface of the L-shaped pin and has better air tightness for adsorbing the pin.

[0010] In some embodiments of the present application, a type block is installed at the bottom surface of the fixed seat, the bottom surface of the type block is provided with a mounting position, the mounting position is adapted to the structure of the L-shaped pin, and the L-shaped pin can be fitted on the bottom surface of the mounting position.

[0011] Specifically, the longitudinal section of the bottom surface of the mounting position is in an inverted L-shaped structure, and the bottom surface of the mounting position comprises a horizontal surface and a vertical surface. In the state of the L-shaped pin being adsorbed by the air nozzle, the top surface of the L-shaped pin is attached to the horizontal surface, and the side surface of the L-shaped pin is attached to the vertical surface. More specifically, the two sides of the horizontal surface are provided with a blocking strip, and the blocking strip cooperates with the vertical surface to limit the displacement of the L-shaped pin in the horizontal direction, thereby ensuring the position accuracy of the L-shaped pin.

[0012] In the present application, the horizontally arranged air nozzle extends into the mold block, and the adsorption surface of the air nozzle is flush with the vertical surface. Under the action of the air nozzle, the L-shaped pin is completely attached to the vertical surface.

[0013] A vertical channel penetrating the horizontal surface is formed in the mold block, the vertically arranged air nozzle extends into the mold block and is installed in the vertical channel, and the adsorption surface of the air nozzle is arranged higher than the horizontal surface. That is, in this case, the L-shaped pin is also completely attached to the horizontal surface, which limits the displacement of the L-shaped pin in the vertical direction and ensures the position accuracy of the L-shaped pin. However, the L-shaped pin is not in contact with the air nozzle, but is directly adsorbed by the vertical channel. The pin suction device of the present application is used to suck the pin after inserting the pin into the insertion position of the insert block in the corresponding work position. Therefore, the mold block or the entire suction nozzle assembly is the force applicator for inserting the pin into the insert block. As an automatic mechanical device, the control system of the present application predefines the stroke value of the downward pressure insertion. In order to ensure that the pin has been inserted into the insertion position, the present application adopts hard contact with the pin, instead of using the extended air nozzle to contact the pin (soft contact), which can avoid the actual back-off of the pin and the insertion of the pin into the corresponding insertion position, resulting in the insert block being a defective product. Of course, correspondingly, the stroke of the pin inserted into the insertion position is not a sufficient stroke, that is, the suction nozzle assembly in the present application moves downward to press and insert into the insert block, and the pin does not reach the limit value of the insertion position. In other words, the pin is inserted by more than half, which ensures that the pin will not fall off at will, and also ensures that the pin will not be inserted too much or too hard, resulting in the insert block being a defective product. The structure of the present application effectively improves the yield of the insert block.

[0014] Specifically, the air nozzle installed in the vertical channel is provided with a sealing structure between the air nozzle and the wall surface of the vertical channel, and the vertical channel is closed near the horizontal surface. This ensures the adsorption capacity of the vertical channel to the L-shaped pin.

[0015] The mechanical arm group involved in the present application comprises a plurality of mechanical arms and a plurality of movable joint members, and the mechanical arms are connected through the movable joint members. The movement of the mechanical arm group in three-dimensional space can be realized by cooperating with the power device.

[0016] A connector pin insertion device includes a rotatable worktable with multiple stations arranged around its outer periphery. The multiple stations correspond to a feeding device, a bending device, a pin insertion picking device, a detection device, and a pin pressing device, respectively. Inserts are installed on the worktable, and the rotation of the worktable causes the inserts to pass through each station in sequence.

[0017] The insert has multiple insertion positions. Each insertion position requires a pin-picking device to pick up an L-shaped pin and insert it into the insertion position to complete the assembly of the insert.

[0018] In some embodiments of this application, the application includes a detection device for detecting that L-shaped pins have been inserted into the corresponding insertion positions on the insert.

[0019] In some embodiments of this application, a pressing device is included, with a push pin provided on the pressing device corresponding to each insertion position of the insert. When the pressing device moves downward, the push pin acts on the insertion pin located in the insertion position, further ensuring that the insertion pin is inserted into the insert in place.

[0020] Based on common knowledge in the field, the above-described embodiments can be combined arbitrarily. Attached Figure Description

[0046] The present application will now be described in detail with reference to the accompanying drawings.

[0047] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0048] A pin-picking device, as described in Embodiment 1 Figures 1 to 4 As shown: It includes a robotic arm assembly 7 and a suction nozzle assembly. The suction nozzle assembly includes a fixed base 41, on which at least two air nozzles 42 are installed. At least one air nozzle 42 is vertically arranged, and at least one air nozzle 42 is horizontally arranged. A gas channel 46 is provided inside the fixed base 41. The gas channel 46 connects an air pump and the air nozzles 42. When the air pump is working, the air nozzles 42 will adsorb the L-shaped needle. The air nozzles 42 on the fixed base 41 act on two different surfaces of the L-shaped needle.

[0049] Example 2, as Figures 1 to 4 Therefore, the adsorption end of the air nozzle 42 adopts a trumpet-shaped structure made of elastic material. This structure allows the adsorption end of the air nozzle 42 to have a certain range of elastic deformation, enabling it to better conform to the surface of the L-shaped pin and achieve better adsorption airtightness for adsorbing the pin.

[0050] A block 43 is installed on the bottom surface of the fixing base 41. The bottom surface of the block 43 is provided with a mounting position 431. The mounting position 431 is adapted to the structure of the L-shaped pin. The L-shaped pin can fit against the bottom surface of the mounting position 431.

[0051] Specifically, the longitudinal section of the bottom surface of the mounting position 431 is an inverted L-shaped structure, and the bottom surface of the mounting position 431 includes a horizontal surface 431a and a vertical surface 431b. When the air nozzle 42 is in the state of adsorbing the L-shaped pin, the top surface of the L-shaped pin is attached to the horizontal surface 431a, and the side surface of the L-shaped pin is attached to the vertical surface 431b. More specifically, baffles 44 are respectively provided on both sides of the horizontal surface 431a. The baffles 44, in conjunction with the vertical surface 431b, restrict the horizontal displacement of the L-shaped pin, ensuring the positional accuracy of the L-shaped pin.

[0052] In this application, a horizontally positioned air nozzle 42 extends into the mold block 43, and the adsorption surface of the air nozzle 42 is flush with the vertical surface 431b. Under the action of the air nozzle 42, the L-shaped pin is completely attached to the vertical surface 431b.

[0053] A vertical channel 45 is provided on the mold block 43, penetrating the horizontal plane 431a. A vertically positioned air nozzle 42 extends into the mold block 43 and is installed within the vertical channel 45, with the adsorption surface of the air nozzle 42 positioned higher than the horizontal plane 431a. At this point, the L-shaped pin is also completely attached to the horizontal plane 431a, controlling its vertical displacement and ensuring its positional accuracy. However, it does not contact the air nozzle 42; instead, it is directly adsorbed by the vertical channel 45.

[0054] Specifically, a sealing structure is provided between the air nozzle 42 installed in the vertical channel 45 and the wall of the vertical channel 45, and the vertical channel 45 is tapered near the horizontal surface 431a. This ensures the vertical channel 45's ability to attract the L-shaped pin.

[0055] The robotic arm assembly 7 involved in this application includes multiple robotic arms and multiple movable joints, with the robotic arms connected to each other via the movable joints. Combined with a power unit, the robotic arm assembly 7 can move in three-dimensional space.

[0056] The rest of the contents of Example 2 are the same as those of Example 1.

[0057] A connector pin device, as described in Embodiment 1 Figure 18 As shown, it includes a rotatable worktable 81, and multiple workstations are arranged on the outer periphery of the worktable 81. The multiple workstations correspond to the feeding equipment, bending device 3, pin insertion and picking device 4, detection device and pin pressing device 6 respectively. The insert 82 is installed on the worktable 81, and the rotation of the worktable 81 drives the insert 82 to pass through each workstation in sequence.

[0058] The insert 82 is provided with multiple insertion slots 82a. Each insertion slot 82a requires the insertion pin picking device 4 to pick up the L-shaped insertion pin and insert it into the insertion slot 82a to complete the assembly of the insert 82.

[0059] This application includes a detection device for detecting that L-shaped pins have been inserted into the corresponding insertion positions 82a on the insert 82.

[0060] This application includes a pressing device 6, on which a push pin is provided for each insertion position 82a corresponding to the insert 82. When the pressing device 6 moves downward, the push pin acts on the insertion pin located in the insertion position 82a, further ensuring that the insertion pin is inserted into the insert 82.

[0061] Example 2: Feeding equipment, such as Figures 7 to 9 As shown, the device includes a strip gripping device 2, which includes a robotic arm assembly 7 and a gripper assembly. The gripper assembly includes a gripper base plate 21. The center of the gripper base plate 21 is connected to a positioning block 24 with positioning pins 23 via a first linear force member 22. The two sides of the gripper base plate 21 are connected to a gripper assembly via a second linear force member 25. The positioning pins 23 are adapted to the positioning holes 924 of the strip substrate 921. The gripper assembly is engaged in the gap between two adjacent pins. The operation of the positioning block 24 and the gripper assembly is independent of each other. When gripping the strip 92, the positioning block 24 first moves downward so that the positioning pins 23 are inserted into the positioning holes 924 of the strip substrate 921, and then the gripper assemblies on both sides move downward to grip the strip 92.

[0062] First, the positioning block 24 and the gripper assembly are connected by independent power components, namely the first linear force component 22 and the second linear force component 25 in this application. Therefore, the positioning block 24 and the gripper assembly in this application are two components that work independently. This allows the positioning block 24 to move first for positioning, and then the gripper assembly to move to grip the strip 92. Second, the chuck base plate 21 is provided, so that the positioning block 24 in the middle and the gripper assemblies on both sides can only have relative vertical displacement with respect to the chuck base plate 21. Structurally, the first linear force component 22 and the second linear force component are fixedly connected to the chuck base plate 21. Therefore, the position of the positioning block 24 and the gripper assembly projected onto the horizontal plane is fixed. Then, the positioning pin 23 is inserted into the positioning hole 924 of the strip substrate 921, and the positioning of the entire chuck base plate 21 is achieved by the positioning of the positioning pin 23. After positioning is achieved, the gripper assemblies located on both sides of the chuck base plate 21 will be able to accurately engage in the gap between two adjacent insert pins without accidentally touching the strip 92. This application effectively improves the working accuracy of the strip gripping device 2 in gripping the strip, thereby effectively improving the yield of insert pins.

[0063] In this application, the design of the conveyor belt structure and the feeding system are coordinated. Specifically, such as... Figures 5 to 6As shown, the unprocessed material belt 92 includes a substrate 921, and a row of pins 922 arranged regularly on one side of the substrate 921, and the pins 922 are connected with the substrate 921. A long and narrow recess 923 is formed at the root of the pin 922, which is the cutting line of the material belt 92. The cutting knife cuts the substrate and the pins along the recess 923, and there is a gap between the pins. A row of positioning holes 924 is regularly arranged on the substrate, and the positioning holes 924 correspond to the pins one by one. The entire material belt 92 is a flat sheet structure.

[0064] One of the concepts of the present application is that the material belt clamping device 2 can directly clamp the material belt from the material tray 91. Therefore, the material tray 91 in the present application is a customized structure designed to cooperate with the material belt clamping device 2 to directly clamp the material belt and improve work efficiency.

[0065] As shown in the drawings, Figure 10 As shown, a plurality of material grooves are regularly arranged on the material tray 91, and the structure of the material grooves is adapted to the structure of the material belt. Two clamping grooves 911 are further provided on the material tray 91, and the clamping grooves 911 penetrate the material grooves and are arranged perpendicular to the material grooves. The distance between the two clamping grooves 911 is equal to the distance between the two jaw sets.

[0066] A groove hole 912 is provided in the material groove, which is adapted to the structure of the positioning pin 23 on the positioning block 24. When the material belt clamping device 2 clamps the material belt on the material tray 91, the positioning pin 23 is inserted into the groove hole 912 after penetrating the material belt. The groove hole 912 corresponds to the positioning pin 23 one by one.

[0067] At least two positioning pins 23 are provided on the positioning block 24. By inserting the two positioning pins 23 into the positioning holes 924 of the material belt substrate, the position of the entire positioning block 24 relative to the material belt substrate can be determined, and the relative position of the chuck bottom plate 21 is further determined.

[0068] The positioning pin 23 includes a head section 23a with a conical structure and a middle section 23b with a cylindrical structure. The diameter of the head section 23a is less than or equal to the diameter of the positioning hole 924 of the material belt substrate, and the diameter of the positioning hole 924 of the material belt substrate is less than the diameter of the middle section 23b. After the positioning pin 23 is inserted into the material belt, the head section 23a penetrates the positioning hole 924 of the material belt substrate, and the outer periphery of the positioning hole 924 is fitted to the head of the middle section 23b. In the present application, a contact sensor is arranged at the head of the middle section 23b to sense whether the material belt substrate is contacted, so as to determine whether the positioning pin 23 is inserted in place to realize positioning.

[0069] The positioning needle 23 further comprises a tail section in cylindrical structure, the diameter of the tail section is larger than that of the middle section 23b. The positioning plate is internally provided with a mounting groove compatible with the tail section structure, the tail end is mounted in the mounting groove and connected with an elastic member, and the elastic member applies an outward extending force to the positioning needle 23.

[0070] In the present application, in order to avoid the positioning needle 23 being damaged in the case of abnormality (the positioning needle 23 moves downward without being aligned with the positioning hole 924), the mounting groove is provided to reserve a certain error stroke distance for the positioning needle 23. Preferably, a sensor for sensing the error retraction of the positioning needle 23 is arranged in the mounting groove, and an alarm is given for the abnormality.

[0071] The jaw set comprises a first jaw 26 and a second jaw 27, the first jaw 26 and the second jaw 27 are oppositely arranged and have the same structure, and the first jaw 26 and the second jaw 27 can approach or move away from each other under the drive of the power device. The first jaw 26 comprises two L-shaped clamping pieces 28 arranged at the bottom, and a spacing is formed between the two clamping pieces 28 for the pins to pass through. When the first jaw 26 and the second jaw 27 cooperate to grab the material belt, one of the jaws is blocked on one side of the substrate, and the jaw part is located at the bottom of the substrate to lift the substrate, and the two clamping pieces 28 of the other jaw pass through the two intervals between the adjacent three pins respectively, and act on the other side of the substrate to block and lift the substrate.

[0072] In the present application, the structure of the substrate does not change, and the spacing between the adjacent two pins does not change, whether the material belt has been processed and bent or not. Therefore, the material belt clamping device 2 in the present application can be applied whether the material belt has been processed and bent or not, and the substrate on the material belt is finally waste material to be cut off, and the pins on the material belt can be prevented from being damaged during grabbing, and the precision of the pins themselves is improved.

[0073] The present application comprises a feeding device 1, as shown in Figures 11 to 12 The feeding device 1 comprises a feeding rack 11 provided with a feeding position 11a, the feeding rack 11 is provided with a lifting support 12, an upper flow line 13 and a lower flow line 14 composed of a conveying belt.

[0074] The lifting support 12 is installed with a roller 121, and the forward rotation and reverse rotation of the roller 121 drives the tray 91 to be input or output to the lifting support 12, the lifting support 12 is installed on a lifting guide rail 15, and the lifting support 12 moves up and down to switch and connect with the upper flow line or the lower flow line.

[0075] The upper feeding position 11a of the lifting support 12 is provided with a light emitter 16 and a light receiver 17 on both sides, and the light emitted by the light emitter 16 is directly opposite to the tray 91 of the upper feeding position 11a. The light emitter 16 and the light receiver 17 are used to detect whether the material belt in the tray is taken away completely. When the material belt is taken away completely, the tray is an empty tray, which can be guided to the upper flow line 13.

[0076] The tray 91 is placed at the initial position of the lower flow line 14, is transported by the lower flow line 14 to the lifting support 12, and the lifting support 12 works between the upper feeding position 11a and the terminal position of the lower flow line 14. The empty tray is output by the lifting support 12 to the upper flow line 13, and then is transported to the tray recycling position 11b by the upper flow line 13.

[0077] In the application, the upper flow line 13 is provided with an empty tray stacking position, and an empty tray clamping assembly 18 is arranged. The empty tray clamping assembly 18 clamps the empty tray at the upper feeding position 11a to the empty tray stacking position for stacking, and then is transported to the tray recycling position 11b after stacking to the predetermined height (a sensor can be additionally arranged at the empty tray stacking position to realize detection).

[0078] In the application, the material belt in the tray is a flat strip structure as shown in Figure 1 , and the pin to be installed on the connector is an L-shaped structure. Therefore, after the material belt on the tray 91 is grabbed, the pin needs to be processed into an L-shaped structure at the bending device 3.

[0079] The other contents of the second embodiment are the same as those of the first embodiment.

[0080] Embodiment three: the application includes a bending device 3, as shown in Figures 13 to 17 , the bending device 3 includes a mounting strip 311, a material blocking strip 312, a bending assembly, and side base plates 32 arranged on both sides of the bending assembly. The tip part of the material belt pin is moved to the mounting strip 311 and the material blocking strip 312 under the action of the material belt clamping device 2, and the material blocking strip 312 moves to clamp the tip part of the material belt pin in cooperation with the mounting strip 311. The side base plates 32 are provided with arc-shaped slide rail groups 321, the bending assembly is connected with the arc-shaped slide rail groups 321 through a plurality of slide columns 33, the slide columns 33 can move along the arc-shaped slide rail groups 321, so that the bending assembly can be turned along a predetermined track, and the bending assembly includes a bending lower plate 341 and a bending pressing plate 342, and the bending pressing plate 342 moves to clamp the base plate of the material belt in cooperation with the bending lower plate 341.

[0081] The movement track of the bending assembly includes a bending position one and a bending position two; when the bending assembly is located at the bending position one, the bending assembly is arranged close to the mounting strip 311, and then the bending pressing plate 342 moves to cooperate with the bending lower plate 341 to clamp the substrate of the material belt; when the bending assembly is located at the bending position two, the clamping surface between the bending lower plate 341 and the bending pressing plate 342 is perpendicular to the clamping surface between the mounting strip 311 and the material blocking strip 312, and then the bending pressing plate 342 moves to release the substrate of the material belt.

[0082] In the bending device 3, the pin portions of the whole material belt are clamped first, the pin portions of the material belt are isolated structures, and the pin portions are the most likely to be deformed; in order to ensure the accuracy of the pins, the pins are clamped and fixed before the bending process, so as to avoid the pins from being deformed beyond the preset during the bending process. Then the bending pressing plate and the bending lower plate clamp the substrate of the material belt, and the bending assembly is turned around the arc-shaped slide rail group 321 of the side substrate 32, so that the material belt is deformed and bent. At this time, the pin is in an L-shaped structure, which is the pin structure in the connector to be formed.

[0083] In the present application, the substrate side is taken as the movable side to avoid the influence on the pins as much as possible. Moreover, the arc-shaped slide rail groups 321 on both sides of the bending assembly sufficiently limit the movement of the bending assembly along the predetermined track, so as to ensure the accuracy during the bending process of the material belt.

[0084] After the material blocking strip 312 moves to clamp the tip portions of the pins of the material belt, the material clamping device 2 exits the space where the bending device 3 is located, so as to avoid the interference between the material clamping device 2 and the bending device 3.

[0085] In the present application, the movement of each component is connected with the component by a driving device, and the component is driven to move. The present application involves the movement of each component, and the driving device is a conventional product in the field, such as a cylinder and a motor. Therefore, the driving device is not written out, but it can be understood by those skilled in the art.

[0086] In the present application, the material belt used as a raw material and not processed in the present application includes a long substrate, a row of pins arranged regularly on one side of the substrate, and a long and narrow recess 923 formed at the root of the pin. The recess 923 is a cutting line of the material belt. A cutting knife cuts the substrate and the pin along the recess 923. There is a gap between the pins. A row of positioning holes 924 are regularly arranged on the substrate, and the positioning holes 924 correspond to the pins one by one. The whole material belt is a flat sheet structure.

[0087] The bending device 3 comprises an oblique top plate 35, which is located obliquely above the mounting strip 311. The surface of the oblique top plate 35 opposite to the material belt on the mounting strip 311 is an inverted L-shaped pressing surface 35a. The oblique top plate 35 moves to press the bent part of the contact pin.

[0088] Specifically, the surface of the mounting strip 311 is an inverted L-shaped mounting surface 311a. The bent contact pin is attached to the mounting surface 311a. The structure of the pressing surface 35a is adapted to the mounting surface 311a. The oblique top plate 35 cooperates with the mounting strip 311 to press the bent part of the contact pin to the mounting surface 311a.

[0089] More specifically, the oblique top plate 35 is connected to an oblique top assembly 36, which drives the oblique top plate 35 to move obliquely downward to press the contact pin. In this application, the oblique top plate 35 and the bending assembly move simultaneously. The base plate of the material belt is bent downward, and the oblique top plate 35 acts on the bent part of the contact pin to make it attach to the mounting surface 311a for bending. Thus, the material belt is fixed by the material blocking strip 312, the oblique top plate 35 and the bending assembly, which ensures the processing precision of the contact pin.

[0090] The bent contact pin is adapted to the structure of the mounting surface 311a. The recess 923 on the material belt protrudes outwardly from the mounting surface 311a. The base plate of the material belt is clamped by the bending assembly. The bending assembly and the mounting strip 311 leave a gap for the cutting knife to insert. The recess 923 on the material belt is located in the gap.

[0091] The bending device 3 further comprises a cutting assembly, which comprises a cutting knife connected to a driving device. The cutting knife is located above the mounting strip 311. The side surface of the mounting strip 311 is a vertical surface. The side surface of the bending lower plate 341 located at the second bending position is a vertical surface perpendicular to the horizontal surface. The side surface of the mounting strip 311 and the side surface of the bending lower plate 341 leave a gap for the cutting knife to insert. The cutting knife moves downward to insert between the mounting strip 311 and the bending lower plate 341, and cuts the material belt along the side surface of the mounting strip 311.

[0092] The mounting strip 311, the material blocking strip 312, the oblique top plate 35 and the oblique top assembly 36 are installed on a straight vibrator 37. The oblique top plate 35 releases the contact pin to leave a gap between the pressing surface 35a and the contact pin. The material blocking strip 312 releases the contact pin to leave a gap between the contact pin and the mounting surface 311a. The straight vibrator 37 works to drive the contact pin located on the mounting strip 311 to move to one end of the mounting strip 311.

[0093] In the present application, the mounting strip 311, the inclined top plate 35 and the material blocking strip 312 constitute a needle containing space similar to the discharge track 38, and the direct vibrator 37 directly realizes the linear conveying of a single needle into the next processing procedure.

[0094] Further, one end of the mounting strip 311 is provided with the discharge track 38 along the length direction of the mounting strip 311, and the discharge track 38 is mounted on the direct vibrator 37. The direct vibrator 37 drives the needle on the mounting strip 311 to move to the discharge port 38a of the discharge track 38. The discharge port 38a of the discharge track 38 is provided with an inductor. The inductor is used to sense whether the needle reaches the discharge port 38a.

[0095] The direct vibrator 37 involved in the present application is the prior art in the field, and its function is to output the needle along the linear discharge track 38.

[0096] In the present application, the bending device 3 is used as a discharge device at the same time, and the bending, cutting, conveying and discharging of the material belt are realized at the bending device 3, so that the processing procedures are integrated, the total time required for the above procedures is saved, the floor space of the equipment is also saved, the work efficiency is improved, and the cost of the equipment is reduced.

[0097] The arc-shaped slide rail group 321 includes two arc-shaped slide rails which do not interfere with each other, and the bending assembly is connected with the two arc-shaped slide rails through the slide column 33. The present application limits the movement track of the bending assembly through the two arc-shaped slide rails, and ensures the precision of the movement of the bending assembly.

[0098] The other contents of the third embodiment are the same as those of the first embodiment or the second embodiment. The above has introduced the present application in detail, and the principles and implementation modes of the present application are described by applying specific examples. The above description of the embodiments is only used to help understand the present application and the core idea. It should be pointed out that the ordinary skilled in the art can make some improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the present application.
