Description

Technical Field

[0001] This invention relates to the field of power distribution. More specifically, this invention relates to an automatic component loading machine and a loading method. Background Technology

[0002] Current small-scale electrical component assembly machines rely entirely on manual operation for component clamping, lacking automated production equipment and exhibiting numerous shortcomings. For example, the feed hoppers using guide rails have limited capacity and low automation. Due to the diverse types and shapes of electrical components, there is a lack of highly adaptable component clamping devices. Current clamping tables for small-scale electrical component assembly machines cannot eliminate gaps between adjacent components after clamping, nor can they complete the splicing of terminals, and they are incompatible with both single-component and composite-component clamping. Summary of the Invention

[0003] This invention provides an automatic electrical component mounting machine and mounting method, which can realize the automated mounting of electrical components, reduce labor costs, and improve product quality.

[0004] To achieve these objectives and other advantages of the present invention, in a first aspect, the present invention provides an automatic electrical component loading machine, comprising: Card mounting station, which includes: A guide rail slide table, on which guide rails are placed and can slide on the guide rail slide table; A clamping detection tongue is positioned above the guide rail slide table. During the clamping process, the tongue of the clamping detection tongue is located inside the guide rail groove on the guide rail slide table and below the position of the clamping electrical component. The clamping detection tongue is connected to a first drive cylinder and moves up and down under the drive of the first drive cylinder. If the tongue moves upward and can lift the electrical component, the clamping fails; otherwise, the clamping is successful. The seam-removing pusher is positioned above the guide rail slide table, spans across the guide rail, is connected to a second drive cylinder, and moves back and forth under the drive of the second drive cylinder to push the successfully mounted electrical component forward to contact the previously successfully mounted electrical component.

[0005] Preferably, in the automatic electrical component mounting machine, the mounting table further includes: a guide rail fixing device, which includes: The guide rail pressure block is located above the guide rail slide table, connected to a third drive cylinder, and moves up and down under the drive of the third drive cylinder. The guide rail pressure tongue is long and narrow. One end of the guide rail pressure tongue is fixed to the bottom surface of the guide rail pressure block. The guide rail pressure block moves downward so that the guide rail pressure tongue presses against the bottom of the groove of the guide rail.

[0006] Preferably, in the automatic electrical component mounting machine, the bottom surface of the seam-removing pusher is provided with a plurality of rectangular grooves, so that the guide rail passes under the seam-removing pusher and the seam-removing pusher pushes the bottom foot of the electrical component; The clamping detection tongue includes a detection plate and a long strip-shaped tongue fixed on the detection plate. The detection plate is connected to the first driving cylinder, and the detection plate is located behind the seam removal push block. The guide rail pressure tongue includes a first pressure tongue part, a second pressure tongue part, and a third pressure tongue part connected in sequence. The width and thickness of the first pressure tongue part are both smaller than the width and thickness of the second pressure tongue part. An elongated hole is provided at the axial position of the first pressure tongue part and the second pressure tongue part. The third pressure tongue part is fixed to the bottom surface of the guide rail pressure block. The locking detection pressure tongue moves downward so that the tongue part is located in the elongated hole. The guide rail pressure block is located behind the detection plate.

[0007] Preferably, in the automatic electrical component loading machine, the mounting table further includes: The first fixed gripper is disposed at the front end of the guide rail slide table. The first fixed gripper includes a left gripper and a right gripper, which are respectively located on both sides of the guide rail on the guide rail slide table. A fourth drive cylinder is connected to the first fixed gripper and is used to control the opening and closing of the first fixed gripper. Specifically, when the electrical component being clamped is a spliced ​​electrical component, the first fixing claw clamps the already clamped front component, and the clamped rear component is pushed by the gap-removing push block to the front end of the guide rail slide table to splice with the clamped front component; when the electrical component being clamped is a non-spliced ​​electrical component, the first fixing claw opens, pushes the guide rail, and allows the clamped electrical component to pass through.

[0008] Preferably, the automatic electrical component packing machine further includes: a splitting mechanism, which includes: The second fixed gripper is located at the front end of the magazine and is fixedly connected to the fifth drive cylinder. It opens and closes under the drive of the fifth drive cylinder to clamp the front component of the splicing electrical component located at the front end of the magazine. The bracket is U-shaped, and the two sides of the bracket are respectively fixed to the base plates on both sides of the magazine; The splitting gripper is located above the magazine and is fixedly connected to the sixth drive cylinder. It opens and closes under the drive of the sixth drive cylinder to clamp the rear component of the splicing electrical components. The sixth drive cylinder is slidably mounted on the bracket. The seventh drive cylinder is fixedly connected to the sixth drive cylinder and is used to drive the sixth drive cylinder to reciprocate back and forth. When the second fixed gripper clamps the front component and the split gripper clamps the rear component, the seventh drive cylinder drives the sixth drive cylinder, the split gripper, and the clamped rear component to move to the rear end, thereby separating the front and rear components of the spliced ​​electrical components.

[0009] Preferably, the automatic electrical component packing machine further includes: a gripper device, which includes: Eighth drive cylinder; A gripper assembly is disposed below and fixedly connected to the eighth drive cylinder. The gripper assembly consists of two symmetrically arranged grippers that grip electrical components on the magazine under the drive of the eighth drive cylinder and clamp them onto the guide rail on the guide rail slide table. A resin material is disposed on the surface of the grippers. A rotating shaft connecting plate is fixedly connected to the eighth drive cylinder, and a positioning pin hole is provided on the lower end of the rotating shaft connecting plate. The gripper support is L-shaped and includes a vertical plate and a horizontal plate. A first through hole is provided on the vertical plate, and a rotary cylinder is fixed on the horizontal plate. The connecting shaft of the rotary cylinder passes through the first through hole and is fixedly connected to the rotary shaft connecting plate. Under the drive of the rotary cylinder, the rotary shaft connecting plate, the eighth drive cylinder, and the gripper assembly swing to the left or right. A second through hole is provided at the lower end of the vertical plate. Two limiting blocks are fixed on the left and right sides of the rotating shaft connecting plate, respectively, and are located on both sides of the vertical plate, to limit the swing angle of the rotating shaft connecting plate. The ninth drive cylinder is connected to a center pin assembly. When the ninth drive cylinder drives the center pin assembly to extend, the center pin assembly passes through the second through hole and enters the pin hole to center the rotating shaft connecting plate. The center pin assembly has a built-in spring. A sensor, which is disposed on the gripper assembly, is used to detect whether the gripper assembly is empty.

[0010] Preferably, the automatic electrical component loading machine further includes a guide rail hopper, which comprises: Multiple independent hoppers, each including: a servo motor connected to a vertically arranged lead screw; and multiple guide rails evenly spaced on the lead screw. Driven by the servo motor, the multiple guide rails perform reciprocating up-and-down linear motion. The guide rail push rod assembly is provided on one side of the multiple guide rail slots in each independent hopper, and is used to push the guide rail in the guide rail slot forward to the guide rail slide table. The frame has multiple independent hoppers mounted on it to connect them into a whole, wherein each guide rail push rod assembly is fixed to the frame. The tenth drive cylinder is connected to the frame and is used to drive the frame to move laterally left and right.

[0011] Preferably, in the automatic electrical component loading machine, the guide rail push rod assembly includes: A rodless cylinder, which is fixed to the frame; The push rod includes a vertical push rod, a horizontal push rod connected to the vertical push rod, and a push block disposed below the end of the horizontal push rod. The vertical push rod is fixedly disposed on the piston of the rodless cylinder. The shape of the push block is adapted to the cross-sectional shape of the guide rail groove so as to enter the guide rail groove and push the guide rail.

[0012] Preferably, in the automatic electrical component loading machine, the guide rail slide table includes a guide rail slide block and baffles fixed on both sides of the guide rail slide block; the gripper device is fixed on a three-dimensional moving device and moves in the X, Y and Z directions under the drive of the three-dimensional moving device.

[0013] Secondly, the present invention also provides a method for mounting electrical components in an automatic mounting machine, applied to the aforementioned automatic mounting machine, comprising: Step 1, Guide rail loading: Drive the guide rail groove in the guide rail hopper to move up and down and left and right, so that the guide rail groove of the guide rail to be clamped is located at the position of the guide rail slide table. The guide rail push rod assembly pushes the guide rail onto the guide rail slide table, and the guide rail fixing device is used to fix the guide rail. Step 2, Installing Electrical Components: The gripper device installs the electrical components from the magazine onto the guide rail. A detection tongue is used to check if the component is successfully installed. If successful, the guide rail remains stationary. A pusher block is used to push the component to a predetermined position. Then, the third drive cylinder drives the guide rail block and guide rail tongue to rise. The guide rail pusher assembly pushes the guide rail forward by the thickness of the electrical component to be installed, continuing the installation of the next component. If the installation fails, the gripper device re-installs the component. Step 3: If the electrical component is a spliced ​​electrical component, the splitting mechanism is used to separate the front and rear components of the spliced ​​electrical component. The gripper device first clamps the front component onto the guide rail and uses the gap-removing push block to push the front component to the position of the first fixed gripper, so that the first fixed gripper clamps the front component. Then the gripper device clamps the rear component onto the guide rail and uses the gap-removing push block to push the rear component to the position of the front component, so that the front and rear components are spliced ​​together. Step 4: After the card is installed, move the guide rail to the receiving platform.

[0014] The present invention has at least the following beneficial effects: Firstly, since the mounting table includes a guide rail slide, mounting detection pressure tongue, gap-removing push block, guide rail pressure block and guide rail pressure tongue, and a first fixed gripper, etc., the mounting detection pressure tongue can detect whether the electrical component is successfully mounted; the gap-removing push block can eliminate gaps between adjacent electrical components after mounting; the guide rail pressure tongue increases the contact area between the guide rail pressure block and the guide rail, thereby increasing the pressure area of ​​the guide rail pressure block and making the guide rail more stable. The shape of the guide rail pressure tongue can also accommodate various types of electrical component corners; the first fixed gripper and the gap-removing push block, combined as a splicing device for electrical components, can splice disassembled electrical components together. The splitting mechanism can automatically separate the front and rear components of the spliced ​​electrical components on the magazine. The cooperation between the splitting mechanism and the first fixed gripper on the mounting table realizes automatic mounting of spliced ​​electrical components and expands the processing range of the electrical component mounting machine.

[0015] Secondly, the gripper device of this invention is highly adaptable, capable of gripping and mounting at least 80% of electrical components on the market, including but not limited to terminals. The gripper assembly can swing left or right at a specified angle, or remain in a neutral position in a horizontal position. The guide rail hopper of this invention increases the storage capacity to more than 45 rails and enables mixed feeding of high and low guide rails, as well as mixed length feeding.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0019] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0020] It should be noted that, unless otherwise specified, the experimental methods described in the following embodiments are conventional methods, and the reagents and materials mentioned are commercially available. In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to fixed connection or setting, detachable connection or setting, or integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The terms "lateral," "longitudinal," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0021] like Figures 1-4 As shown, this embodiment of the invention provides an automatic electrical component mounting machine, including: a mounting table 1, which includes: a guide rail slide table 110, on which a guide rail is placed and the guide rail can slide on the guide rail slide table 110; a mounting detection tongue 120, which is disposed above the guide rail slide table 110. During the mounting process, the tongue 1202 of the mounting detection tongue 120 is located inside the guide rail groove on the guide rail slide table 110 and below the mounting position of the electrical component. The mounting detection tongue 120 and a first... A drive cylinder 121 is connected and moves up and down under the drive of the first drive cylinder 121. The tongue 1202 moves upward and can lift the electrical component. If it can, the mounting fails. If it cannot, the mounting is successful. The gap pusher 130 is set above the guide rail slide table 110, spans the guide rail, is connected to a second drive cylinder 131, and moves back and forth under the drive of the second drive cylinder 131 to push the successfully mounted electrical component forward to contact the previously successfully mounted electrical component.

[0022] In the above embodiment, the guide rail slide table 110 is specifically configured to include a guide rail slide block 112 and baffles 111 fixed on both sides of the guide rail slide block. The baffles 111 on both sides can limit the left and right position deviation of the guide rail. The width of the guide rail slide block 112 is slightly smaller than that of the guide rail, allowing the guide rail to slide on the guide rail slide block. To prevent material jamming, the front ends of the left and right baffles on both sides are rounded, and their height is slightly higher than the upper surface of the guide rail slide block, so that the bottom surface of the guide rail can contact the guide rail slide block. The thickness of the baffles is approximately 0.1 mm; excessive thickness would interfere with the electrical components after installation. In this embodiment of the invention, the direction of movement of the guide rail is set to forward. The guide rail slide block and the baffles on both sides can also be configured as an integrated structure.

[0023] Since most electrical components are not square or rectangular, but come in various types and shapes, mounting failures frequently occur during the mounting process. Therefore, the success of mounting is crucial for achieving automated control. In this embodiment of the invention, a mounting detection tongue 120 is provided, with its tongue 1202 positioned inside the guide rail groove on the guide rail slide table 110, below the mounting position of the electrical component. If the tongue 1202 moves upward and can lift the electrical component, it indicates a mounting failure; otherwise, it indicates a successful mounting. Therefore, the mounting detection tongue 120 can automatically and quickly determine whether the electrical component is mounted successfully. The gap-removing pusher 130 pushes the successfully mounted electrical component forward to contact the previously mounted component, eliminating gaps between adjacent successfully mounted electrical components, ensuring that the gap between adjacent electrical components is less than or equal to 0.1 mm.

[0024] In one specific embodiment, the automatic electrical component mounting machine further includes a mounting table 1 with a guide rail fixing device, comprising: a guide rail pressing block 140, which is disposed above the guide rail slide table 110, connected to a third drive cylinder 141 and moving up and down under the drive of the third drive cylinder 141; and a guide rail pressing tongue 160, which is elongated, with one end of the guide rail pressing tongue 160 fixed to the bottom surface of the guide rail pressing block 140, and the guide rail pressing block 140 moving downward to press the guide rail pressing tongue 160 against the bottom of the groove of the guide rail.

[0025] In the above embodiments, a guide rail fixing device is provided for fixing the guide rail. Since the guide rail can slide on the guide rail slide table 110, when installing electrical components, the guide rail is very likely to move forward or backward, leading to installation failure. Therefore, fixing the guide rail when it is not moving is also crucial. In this embodiment of the invention, not only is a guide rail pressure block 140 provided, but also an elongated guide rail pressure tongue is provided, which increases the contact area with the guide rail and also increases the area of ​​pressure applied to the guide rail, making the guide rail more stable and reliable. It should also be noted that the specific setting of the guide rail pressure block 140 must be compatible with the TS35 high and low guide rail feeding. Therefore, the stroke selection of the third drive cylinder 141 should ensure that the rising height does not make the upper surface of the guide rail pressure block 140 higher than the upper surface of the low guide rail of the TS35.

[0026] In one specific embodiment, the automatic electrical component loading machine, such as Figures 1-4 As shown, the bottom surface of the seam-removing push block 130 is provided with a plurality of rectangular grooves 132, allowing the guide rail to pass under the seam-removing push block 130 and allowing the seam-removing push block 130 to push the base of the electrical component; the clamping detection tongue 120 includes a detection plate 1201 and a long strip-shaped tongue 1202 fixed on the detection plate 1201, the detection plate 1201 is connected to the first drive cylinder 121, wherein the detection plate 1201 is located behind the seam-removing push block 130; the guide rail tongue 160 includes a first tongue portion connected in sequence. 161. A second pressing tongue portion 162 and a third pressing tongue portion 163, wherein the width and thickness of the first pressing tongue portion 161 are both smaller than the width and thickness of the second pressing tongue portion 162, and an elongated hole 164 is provided at the axial position of the first pressing tongue portion 161 and the second pressing tongue portion 162, and the third pressing tongue portion 163 is fixed to the bottom surface of the guide rail pressing block 140, wherein the clamping detection pressing tongue 120 moves downward so that the tongue portion 1202 is located in the elongated hole 164, and the guide rail pressing block 140 is located behind the detection plate 1201.

[0027] In the above specific embodiments, the specific shape of the gap-removing push block 130 is defined. Since the gap-removing push block 130 is mounted on the guide rail, but cannot affect the movement of the guide rail, the gap-removing push block 130 must avoid the side walls and edges of the guide rail. Furthermore, since the gap-removing push block 130 pushes the electrical components to move, and different electrical components have different shapes, to avoid tilting during pushing, it is best to allow the gap-removing push block 130 to push the bottom feet of the electrical components. Therefore, in this embodiment of the invention, a plurality of rectangular grooves 132 are provided on the bottom surface of the gap-removing push block 130 to facilitate the passage of the guide rail and the pushing of the bottom feet of the electrical components. The clamping detection tongue 120 is provided with an L-shaped detection plate 1201 and a long strip tongue 1202 fixed on the detection plate 1201. The detection plate 1201 is set in an L-shape, and the tongue 1202 is fixed to the end of the horizontal plate of the detection plate 1201 by a connecting block 1203, so as to avoid the side wall and edge of the guide rail, allowing the tongue 1202 to be located in the groove of the guide rail, and also to facilitate the connection of the detection plate 1201 to the first drive cylinder 121. The guide rail clamping tongue is set as a first clamping tongue 161, a second clamping tongue 162, and a third clamping tongue 163 connected in sequence, mainly to be compatible with the clamping angle of various types of electrical components. For different electrical components, depending on the clamping angle, they can be clamped on the top of the first clamping tongue 161 or the top of the second clamping tongue 162.

[0028] In one specific embodiment, the automatic electrical component mounting machine further includes a mounting table 1 comprising: a first fixed gripper 150 disposed at the front end of the guide rail slide table 110, the first fixed gripper 150 including a left gripper and a right gripper, respectively located on both sides of the guide rail on the guide rail slide table 110; and a fourth drive cylinder 151 connected to the first fixed gripper 150 for controlling the opening and closing of the first fixed gripper 150. When the mounted electrical component is a splicing electrical component 5, the first fixed gripper 150 clamps the already mounted front component, and the mounted rear component is pushed by the seam-removing pusher 130 to the front end of the guide rail slide table 110 to splice with the clamped front component. When the mounted electrical component is a non-splicing electrical component 5, the first fixed gripper 150 opens, pushes the guide rail, and allows the mounted electrical component to pass through.

[0029] In the above embodiment, the purpose of setting the first fixing jaw 150 and the fourth driving cylinder 151 is to splice the two parts of the splicing electrical component 5 together. Therefore, when the electrical component is a splicing electrical component 5, after the seam-removing push block 130 pushes the front component to the position of the first fixing jaw 150, the guide rail does not move. The first fixing jaw 150 clamps the front component, and then the rear component is clamped. After successful clamping, the seam-removing push block 130 pushes the rear component to the position of the front component for splicing. The entire splicing process is automated. After a splicing electrical component 5 is spliced, the first fixing jaw 150 opens, the third driving cylinder 141 drives the guide rail pressing block 140 and the guide rail pressing tongue to rise, the guide rail push rod assembly pushes the guide rail forward by the thickness distance of the next splicing electrical component 5 to be clamped, the third driving cylinder 141 drives the guide rail pressing block 140 and the guide rail pressing tongue to move down to fix the guide rail, and the clamping of the next splicing electrical component 5 continues. When the electrical component is a non-spliced ​​electrical component 5, the first fixing jaw 150 is always in the open state. After successful clamping, the guide rail does not move. The gap-removing push block 130 is used to push the electrical component to the predetermined position. Alternatively, if there is already a clamped electrical component on the guide rail, the electrical component is pushed to contact the previously clamped electrical component. Then, the third drive cylinder 141 drives the guide rail pressing block 140 and the guide rail pressing tongue to rise, pushing the guide rail forward by the thickness distance of the electrical component to be clamped. The guide rail fixing device fixes the guide rail, and the clamping of the next electrical component continues. The predetermined position to which the gap-removing push block 130 is pushed can be the front end of the guide rail slide table 110, or other pre-set positions, as long as the entire clamping process can be realized. The shape of the left and right jaws of the first fixing jaw 150 is not specifically limited in this embodiment of the invention. Preferably, they are L-shaped to facilitate clamping the electrical component. It should be noted that, due to the relatively long guide rail, after mounting one electrical component, the guide rail needs to be advanced by the thickness of the component to be mounted, thus allowing electrical components to be mounted one after another at the mounting position. After one guide rail is mounted, the unloading assembly 13 moves the guide rail to the receiving platform. Specifically, the servo module drives the guide rail grippers to move the guide rail with the mounted electrical components to the designated position, and then the pusher cylinder pushes the guide rail onto the receiving platform. The unloading assembly uses existing technology, and this embodiment of the invention will not impose specific limitations on it.

[0030] In one specific embodiment, the automatic electrical component loading machine, such as Figure 5As shown, it also includes: a splitting mechanism 2, which includes: a second fixed gripper 210, which is disposed at the front end of the magazine 7 and fixedly connected to the fifth drive cylinder 211, opening and closing under the drive of the fifth drive cylinder 211, for clamping the front component of the splicing electrical component 5 located at the front end of the magazine 7; a bracket 6, which is U-shaped, with the two sides of the bracket 6 fixed to the base plates on both sides of the magazine 7; and a splitting gripper 220, which is disposed above the magazine 7 and fixedly connected to the sixth drive cylinder 221, opening and closing under the drive of the sixth drive cylinder 221, for clamping the splicing component. The rear component of electrical component 5 includes a sixth drive cylinder 221 slidably mounted on the bracket 6; a seventh drive cylinder 230 fixedly connected to the sixth drive cylinder 221 for driving the sixth drive cylinder 221 to reciprocate back and forth; wherein, when the second fixing claw 210 clamps the front component and the splitting claw 220 clamps the rear component, the seventh drive cylinder 230 drives the sixth drive cylinder 221, the splitting claw 220, and the clamped rear component to move rearward, separating the front and rear components of the spliced ​​electrical component 5.

[0031] In the above specific embodiment, the splitting mechanism 2 enables automated control of the splitting of the spliced ​​electrical components 5. Specifically, the left and right jaws of the second fixed gripper 210 are located on both sides of the magazine 7. For the splitting gripper 220, preferably, the left and right jaws each include two clamping parts. The first clamping part 2201 clamps one part in an L-shape, and the second clamping part 2202 is fixedly disposed on the outer surface of the first clamping part 2201, clamping another part in an L-shape. This allows for better separation of the rear component from the front component, enabling the individual mounting of the front and rear components. Therefore, the cooperation between the splitting mechanism 2 and the first fixed gripper 150 on the mounting table 1 enables automatic mounting of the spliced ​​electrical components 5 and expands the processing range of the electrical component mounting machine.

[0032] It should be noted that, regarding the storage bins for electrical components, the magazines can be pneumatic magazines driven by rodless cylinders or magazines driven by other drive mechanisms. Multiple magazines can be combined together to form the storage bins for electrical components.

[0033] In one specific embodiment, the automatic electrical component loading machine, such as Figures 6-8As shown, it also includes: a gripper device 3, which includes: an eighth drive cylinder 320; a gripper assembly 310, which is disposed below and fixedly connected to the eighth drive cylinder 320, the gripper assembly 310 consisting of two symmetrically arranged grippers, which, driven by the eighth drive cylinder 320, grip the electrical components 8 on the magazine 7 and clamp them onto the guide rail on the guide rail slide table 110, wherein a resin material is disposed on the surface of the grippers; a rotating shaft connecting plate 330, which is fixedly connected to the eighth drive cylinder 320, and a positioning pin hole is provided on the lower end of the rotating shaft connecting plate 330; a gripper support member 350, which is L-shaped, including a vertical plate 352 and a horizontal plate 351, a first through hole is provided on the vertical plate 352, and a rotating cylinder 360 is fixed on the horizontal plate 351, the connecting shaft 361 of the rotating cylinder 360 passes through the first through hole and is connected to the horizontal plate 351. The rotating shaft connecting plate 330 is fixedly connected. Driven by the rotating cylinder 360, the rotating shaft connecting plate 330, the eighth driving cylinder 320, and the gripper assembly 310 swing to the left or right. A second through hole 353 is provided at the lower end of the vertical plate 352. Two limiting blocks 340 are fixed on the left and right sides of the rotating shaft connecting plate 330, respectively, and are located on both sides of the vertical plate 352 to limit the swing angle of the rotating shaft connecting plate 330. A ninth driving cylinder 370 is connected to a center pin assembly 380. When the ninth driving cylinder 370 drives the center pin assembly to extend, the center pin assembly passes through the second through hole 353 and enters the pin hole to center the rotating shaft connecting plate 330. The center pin assembly 380 has a built-in spring. A sensor 9 is provided on the gripper assembly 310 to detect whether the gripper assembly 310 is not gripping properly.

[0034] In the above embodiments, the specific settings are as follows: Figure 8As shown, the center pin assembly 380 includes a center pin 381, a spring 382, ​​and a threaded plug 383. Therefore, the spring 382 pushes out the center pin 381, providing flexibility. Adding resin material to the gripper surface protects the electrical component surface and increases friction, making the gripper grip more secure. The gripper can also be replaced with a flexible gripper, which has the same function but is more adaptable to electrical components with uneven surfaces. The fixed stroke of the eighth drive cylinder 320 is 80mm. The opening and closing position of the gripper assembly 310 can be adjusted by the position of the gripper assembly 310 on the eighth drive cylinder 320. The two limit stops 340 allow the gripper assembly 310 to swing left or right within a certain range. The swing angle of the gripper assembly 310 can be adjusted by adjusting the position of the limit stops 340. Under normal conditions, the ninth drive cylinder 370 drives the center pin assembly to extend, passing through the second through hole 352 and entering the pin hole, thereby keeping the rotating shaft connecting plate 330 and the gripper assembly 310 in the center position. Specifically, a linear bearing can be installed in the second through hole to facilitate the sliding of the center pin assembly within it. After the gripper assembly 310 has finished gripping, the ninth drive cylinder 370 drives the center pin assembly to retract, and the rotating cylinder 360 drives the gripper assembly 310, the eighth drive cylinder 320, the rotating shaft connecting plate 330, and the connecting shaft to swing left or right. The limit stop block 340 restricts the stopping position of the swing. During clamping, the ninth drive cylinder 370 drives the center pin assembly to extend and press against the rotating shaft connecting plate 330. Because the center pin assembly has a built-in spring, it does not restrict the rotation of the rotating shaft connecting plate 330. During clamping, the gripper assembly 310, the eighth drive cylinder 320, and the rotating shaft connecting plate 330 gradually return to a horizontal position, the center pin assembly is inserted into the pin hole, and the gripper assembly 310 returns to the center position. Since electrical components have various shapes and are not standard square shapes, during clamping, to allow the gripper assembly 310 to adapt, the clamping angle of the electrical component is clamped onto the edge of the guide rail, and the gripper assembly 310 is configured to rotate. Therefore, the gripper device 3 provided in this embodiment of the invention has strong adaptability and can handle at least 80% of electrical components on the market, including but not limited to terminals. Specifically, the gripper device 3 is fixed to a three-dimensional moving device 11 and moves in the X, Y, and Z directions under the drive of the three-dimensional moving device 11. The embodiments of the present invention do not impose specific limitations on the specific structure of the three-dimensional moving device, as long as it can achieve the function.

[0035] In one specific embodiment, the automatic electrical component loading machine, such as Figures 9 to 11As shown, it also includes a guide rail hopper 4, which comprises: multiple independent hoppers, each of which includes: a servo motor 410 connected to a vertically arranged lead screw 411; multiple guide rail grooves 420, which are equally spaced on the lead screw 411, and under the drive of the servo motor 410, the multiple guide rail grooves 420 perform reciprocating up-and-down linear motion; a guide rail push rod assembly 440, which is provided on one side of the multiple guide rail grooves 420 in each independent hopper, for pushing the guide rail in the guide rail groove forward to the guide rail slide table 110; a frame 430, on which the multiple independent hoppers are arranged to connect the multiple independent hoppers into a whole, wherein each guide rail push rod assembly 440 is fixed on the frame 430; and a tenth drive cylinder 450, which is connected to the frame 430 for driving the frame 430 to move laterally left and right. Specifically, the guide rail push rod assembly 440 includes: a rodless cylinder 441, which is fixed on the frame 430; a push rod 442, which includes a vertical push rod, a horizontal push rod connected to the vertical push rod, and a push block disposed below the end of the horizontal push rod. The vertical push rod is fixedly disposed on the piston of the rodless cylinder 441, and the shape of the push block is adapted to the cross-sectional shape of the guide rail groove 420 so as to enter the guide rail groove and push the guide rail.

[0036] In the above specific embodiment, the setting of multiple independent hoppers increases the storage capacity of the guide rail, and each independent hopper can achieve individual material supply. Preferably, there can be three hoppers: hopper one can hold 16 pieces of material; hopper two can hold 16 pieces of material; and hopper three can hold 16 pieces of material, bringing the total storage capacity to more than 45 pieces. The guide rail slots can be made of sheet metal, with a width slightly wider than the width of the guide rail and a height slightly higher than the height of the TS35 high rail. Each guide rail slot can hold both TS35 high rails and TS35 low rails. The servo motor is used for the vertical linear motion of the guide rail, the tenth drive cylinder is used for the horizontal left and right movement of the guide rail, and the rodless cylinder is used to facilitate the push rod to push the guide rail in the guide rail slot to move forward and backward. Therefore, the guide rail hopper can realize the vertical, horizontal, left and right, forward and backward movement of the guide rail material in space, completing the automatic feeding of the guide rail. In specific settings, it is also possible to use sensor 9 and CCD camera to identify the guide rail model and length. These devices can all use existing technologies, and the embodiments of the present invention will not be specifically limited. Regarding the lateral movement of the control frame, a mid-position stop cylinder 460 can be added to stop the frame 430. Specifically, the tenth drive cylinder and the mid-position stop cylinder 460 are mounted on a bottom frame 470, and the frame 430 is mounted above the bottom frame 470 and connected to the piston rod of the tenth drive cylinder 450. The specific mounting method is not limited in this invention, as long as the function can be achieved.

[0037] In practice, the guide rail hopper can be replaced with another guide rail feeding device, such as... Figure 12 As shown. The guide rail feeding device 10 includes a second servo motor 1010, which drives the linear module to move; a linear module 1020, which drives the push block to move back and forth; a guide rail push block 1030, which pushes the guide rail forward; a front stop block 1040, which blocks the guide rail on the belt and plays a role in lateral alignment. The stop block has a groove so that the edge of the guide rail is embedded in the groove to prevent the guide rail from tipping over during belt rotation; a conveyor belt 1050, which transports the guide rail; and a side stop block 1060, which is used to align the front end of the guide rail. The implementation is as follows: the guide rail is placed with its front end against the edge of the side stop block; the belt rotates, and the side wall and edge of the guide rail come into contact with the front stop block and then stop; the second servo motor drives the linear module and the guide rail push block to move, and the guide rail push block pushes the guide rail out.

[0038] Another embodiment of the present invention provides a method for mounting electrical components in an automatic mounting machine, applied to the aforementioned automatic mounting machine, comprising: Step 1, Guide rail loading: The servo motor drives the guide rail groove to move up and down in a linear motion, and the tenth drive cylinder drives the frame to move left and right, so that the guide rail groove of the guide rail to be clamped is located at the position of the guide rail slide table 110. The guide rail push rod assembly pushes the guide rail onto the guide rail slide table 110, and the guide rail fixing device is used to fix the guide rail.

[0039] Step 2, Installing Electrical Components: The gripper device 3 installs the electrical components on the magazine 7 onto the guide rail. The clamping detection tongue 120 is used to detect whether the electrical components are successfully installed. If the installation is successful, the guide rail does not move. The gap-removing push block 130 pushes the electrical components to the predetermined position. Then, the third drive cylinder 141 drives the guide rail pressure block 140 and the guide rail pressure tongue to rise. The guide rail push rod assembly pushes the guide rail forward by the thickness of the electrical component to be installed. The third drive cylinder 141 drives the guide rail pressure block 140 and the guide rail pressure tongue to fall down to fix the guide rail and continue to install the next electrical component. If the installation is unsuccessful, the gripper device 3 re-installs the components.

[0040] It should be noted that, due to the relatively long guide rail, the guide rail push rod assembly can initially only push a portion of the guide rail onto the guide rail slide table 110. After an electrical component is installed and pushed to the predetermined position, the guide rail push rod assembly pushes the guide rail forward by the thickness of the electrical component to be installed, and then continues to install the next electrical component.

[0041] Step 3: If the electrical component is a spliced ​​electrical component 5, the splitting mechanism 2 is used to separate the front and rear components of the spliced ​​electrical component 5. The gripper device 3 first clamps the front component onto the guide rail, and then uses the seam-removing push block 130 to push the front component to the position of the first fixed gripper 150, so that the first fixed gripper 150 clamps the front component. Then the gripper device 3 clamps the rear component onto the guide rail, and uses the seam-removing push block 130 to push the rear component to the position of the front component, so that the front and rear components are spliced ​​together.

[0042] Step 4: After the card is installed, move the guide rail to the receiving platform.

[0043] It should be noted that the guide rail hopper 4, clamping table 1, magazine 7, splitting mechanism 2, gripper device 3, three-dimensional moving device 11, and unloading assembly 13 are all rationally integrated into a large frame 12, such as... Figures 12 to 15 As shown, all the drive cylinders and servo motors involved in this embodiment of the invention are connected to a PLC control system, forming a complete electrical component loading machine, realizing the automatic loading of electrical components.

[0044] It should also be noted that, in the embodiments of the present invention, the driving cylinder used can also be implemented using other driving mechanisms, such as driving motors, cams, etc. Any driving mechanism that can achieve the driving function in the embodiments of the present invention is within the scope of protection of the embodiments of the present invention.

[0046] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
