Description

Technical Field

[0001] The present invention relates to a production structure of a capacitor, in particular to a capacitor PIN foot cutting device. Background Art

[0002] With the development of electronic products, capacitors are widely used in various devices, especially on circuit boards. In the traditional capacitor production process, the shearing operation of PIN feet usually needs to rely on manual labor, with low efficiency and easy to produce errors. Therefore, there is an urgent need in the market for a mechanical device that can automatically perform the automated shearing of PIN feet to improve production efficiency, reduce labor costs, and ensure the stability of product quality.

[0003] To solve the above technical problems, in the prior art, as shown in the patent automatic foot cutting machine (publication number CN207494463U), although it improves the automation degree of PIN cutting, since the products it feeds need to ensure that they are products that have passed inspection and are qualified in other processes, that is, the PIN feet have no defects such as bending. Otherwise, it is still difficult to eliminate the existence of errors during direct shearing. Therefore, the accuracy of the obtained products is also relatively low. Even if the straightening of the PIN feet has been completed in the previous process and the error of PIN foot bending has been eliminated, when re-feeding to this shearing device, bending may still occur, thus affecting the accuracy of the subsequent shearing results. Summary of the Invention

[0004] To solve the above technical problems, the object of the present invention is to provide a capacitor PIN foot cutting device that can continuously complete the operations of straightening, aligning, and shearing the capacitor PIN needles after the capacitor is loaded, so as to eliminate the errors in the pre-shearing standards caused by PIN needle bending, positioning defects, etc., and improve the production accuracy of the capacitor.

[0005] The present invention provides the following technical solutions:

[0006] A capacitor PIN foot cutting device includes an adjustment part and a shearing part. The adjustment part includes four groups of workstations distributed at intervals of 90°. The four groups of workstations are in turn a feeding workstation, a straightening workstation, a detection workstation, and a shearing workstation. And a set of rotating motor drives the rotation of four groups of pneumatic grippers to alternately place them at the four groups of workstations. The pneumatic gripper at the feeding workstation is used to relax the capacitor for the unloading of the capacitor after shearing and receive the loading of a new round of capacitors to be sheared. The pneumatic gripper at the straightening workstation is used to clamp the capacitor to straighten the capacitor PIN feet. The pneumatic gripper at the detection workstation is used to clamp the capacitor to perform the electrical connection detection of the capacitor PIN feet after straightening. The shearing part then shears the capacitor PIN feet that pass the electrical connection detection, so that the lengths of the two PIN feet of the capacitor are the same.

[0007] At this point, when the pneumatic gripper at the feeding station holds the capacitor that has been sheared, it first relaxes to discharge the sheared capacitor, and then a new round of capacitor feeding is carried out. After the capacitor is fed at the feeding station, the operations of straightening, detecting, and shearing can be carried out continuously. Then, after shearing, it rotates to the feeding station again for discharging. The continuous operation can ensure the shearing accuracy, and the operations of straightening and detecting can directly and automatically eliminate the standard errors before shearing caused by PIN foot bending, positioning defects, etc. before shearing, so as to improve the production accuracy of the capacitor.

[0008] Preferably, the adjustment part includes a group of substrates with a rotary motor installed in the middle and a straightening group and a detecting group positioned at the edges of the substrate. The straightening group is located at the straightening station and is used to straighten the PIN feet of the capacitor held by the pneumatic gripper. The detecting group is located at the detecting station and is used to detect the length of the PIN feet of the capacitor held by the pneumatic gripper. The driving end of the rotary motor passes through the substrate to position a group of horizontal cross-shaped positioning plates. Four pneumatic grippers are respectively positioned at the four ends of the cross-shaped positioning plates. The center of the cross-shaped positioning plate also positions a group of rotary joints through an arched frame. The rotary end of the rotary joint is installed on the cross-shaped positioning plate, and the fixed end of the rotary joint is connected above the substrate through a bracket. The rotary end and the fixed end of the rotary joint are connected in a transfer manner, and an air passage cavity is opened in the middle. The periphery of the rotary end is connected to the finger cylinder connection ends of the four pneumatic grippers through four rotary pipe joints, and the periphery of the fixed end is connected to the air source end through fixed pipe joints. At this point, a relatively simple and neatly arranged connection structure is formed, which is also convenient for subsequent personnel maintenance.

[0009] Preferably, the straightening group includes a straightening cylinder installed on the substrate through a straightening mounting plate and a finger gripper installed at the driving end of the straightening cylinder. The clamping center of the finger gripper is aligned directly below the clamping end of the pneumatic gripper rotated to the straightening station. When the pneumatic gripper holds the capacitor and rotates above the finger gripper, the straightening cylinder pushes the finger gripper upward, so that the two clamping ends of the finger gripper are placed on both sides of the PIN foot. Then, the finger gripper clamps the end of the PIN foot and is driven downward by the straightening cylinder so that the PIN foot with a snake-shaped bend can be straightened.

[0010] Preferably, two sets of clamping ends of the finger gripper are respectively connected with a set of spacer plates through a set of horizontal push cylinders. The two sets of spacer plates are arranged oppositely and horizontally placed between the finger gripper and the pneumatic gripper. At the center of the end of one set of spacer plates, there is a partition that spaces between two PIN feet. The connection end of the partition and the corresponding spacer plate is a smooth inclined surface that flares away from the partition. At the center of the end of the other set of spacer plates, there is a slot for the partition to be inserted, and the connection end of the slot and the corresponding spacer plate is a smooth groove surface that flares away from the slot. Thus, after the two clamping ends of the finger gripper rise to both sides of the PIN feet, then drive the horizontal push cylinder to push the spacer plates to move. The flared smooth inclined surface is used to expand the PIN feet that are bent inward to both sides, and the flared smooth groove surface is used to narrow inward the PIN feet that are bent outward. Until the distance between the PIN feet is the same as the distance between the PIN pins and the root of the capacitor connection, then clamp the end of the PIN feet with the clamping ends of the pneumatic finger gripper, and when pulling down with the straightening cylinder, the straightening of the PIN feet can be realized.

[0011] Preferably, the clamping end of the pneumatic gripper is provided with a right-angle groove for receiving and positioning the capacitor housing. At the end of the right-angle groove, there is also a stop bar for blocking the capacitor in place. The two right-angle grooves of the pneumatic gripper form a clamp for holding the capacitor housing.

[0012] Preferably, at the bottom of the clamping end of the pneumatic gripper, there is also a set of positioning clamps driven by an electric push rod. The two pairs of positioning clamps of the pneumatic gripper are arranged oppositely and are used to correspondingly abut against both sides of the root of the PIN pin. Thus, before the straightening operation, the electric push rod can drive the positioning clamps to clamp the root of the PIN pin, and when straightening the PIN feet, the PIN pin will not be easily pulled off from the capacitor.

[0013] Preferably, on the bracket, there is also a set of pressure cylinders connected through a connecting frame extending above the straightening station. The driving end of the pressure cylinder is used to push the capacitor housing to place it in the right-angle groove to prevent a gap between the bottom of the right-angle groove and the capacitor when the pneumatic gripper clamps the capacitor, thereby causing a shearing error during shearing.

[0014] Preferably, the detection group includes a driving cylinder installed on the substrate, two sets of detection cylinders installed on the driving end of the driving cylinder, and two pairs of metal probes installed on the driving of the detection cylinders. The driving cylinder is used to push the detection cylinders so that the two pairs of metal probes rise to both sides of the two PIN pins, and the detection cylinders are used to push the two pairs of metal probes towards each other to contact the PIN feet for electrical connection detection.

[0015] Preferably, the shearing part includes an X-direction cylinder for installing an electric scissors to move in the X direction, a Y-direction cylinder for driving the X-direction cylinder to move in the Y direction, and a Z-direction cylinder for driving the Y-direction cylinder to move in the Z direction. Therefore, after the capacitor PIN pins with qualified electrical connection are moved to the shearing station, the final shearing of the PIN pins can be achieved through the driving of the X-direction cylinder, Y-direction cylinder, and Z-direction cylinder.

[0016] The beneficial effects of the present invention are as follows: A capacitor PIN pin cutting device provided by the present invention can continuously complete the operations of straightening, aligning, and shearing the capacitor PIN pins after the capacitor is loaded, so as to eliminate the errors in the standards before shearing caused by PIN pin bending, positioning defects, etc., and improve the production accuracy of the capacitor.

[0017] During straightening, that is, when the pneumatic gripper grips the capacitor and rotates it to directly above the finger gripper, the straightening cylinder pushes the finger gripper upward, so that the two clamping ends of the finger gripper are placed on both sides of the PIN pin. Then, the finger gripper clamps the end of the PIN pin, and under the drive of the straightening cylinder, it drives downward so that the PIN pin with a serpentine bend can be straightened. In order to further improve the straightening accuracy, spacer plates can be added. After the two clamping ends of the finger gripper rise to both sides of the PIN pin, the horizontal push cylinder is then driven to push the spacer plates to move. The flared smooth inclined surface is used to expand the PIN pins bent inward to both sides, and the flared smooth groove surface is used to narrow the PIN pins bent outward inward until the distance between the PIN pins is the same as the distance between the PIN pins and the root of the capacitor connection. Then, the clamping ends of the pneumatic finger gripper clamp the end of the PIN pin, and when it is pulled down with the straightening cylinder, the straight-line alignment of the PIN pin can be achieved.

[0030] Embodiment 1

[0031] As Figures 1-7 shown, a capacitor PIN foot cutting device, in this embodiment, includes an adjusting part 1 and a shearing part 2. The adjusting part 1 includes four groups of stations distributed at 90° intervals. The four groups of stations are in sequence the feeding station 3, the straightening station 4, the detection station 5, and the shearing station 6. And a group of rotary motors 7 drive four groups of pneumatic grippers 8 to rotate for alternately placing at the four groups of stations. The pneumatic gripper 8 at the feeding station 3 is used to relax the capacitor 9 for the discharging of the sheared capacitor 9 and receiving the feeding of a new round of capacitors 9 to be sheared. The pneumatic gripper 8 at the straightening station 4 is used to clamp the capacitor 9 for straightening the PIN feet 10 of the capacitor 9. The pneumatic gripper 8 at the detection station 5 is used to clamp the capacitor 9 for the electrical connection detection of the PIN feet 10 of the straightened capacitor 9. The shearing part 2 shears the PIN feet 10 of the capacitors 9 that pass the electrical connection detection, so that the lengths of the two PIN feet 10 of the capacitor 9 are the same;

[0032] At this point, when the pneumatic clamp 8 of the feeding station 3 clamps the capacitor 9 that has been sheared, it is first relaxed to unload the capacitor 9 after shearing, and then a new round of loading of the capacitor 9 is carried out. After the capacitor 9 is loaded at the feeding station 3, the straightening, testing and shearing operations can be continuously performed, and then after the shearing is completed, it is rotated to the feeding station 3 again for unloading. The continuous operation can ensure the shearing accuracy, and the straightening and testing operations can also directly and automatically eliminate the standard errors before shearing caused by bending of the PIN foot 10 and positioning defects before shearing, so as to improve the production accuracy of the capacitor 9.

[0033] The adjustment part 1 includes a base plate 11 with a rotating motor 7 installed in the middle, and a straightening group 12 and a detection group 13 positioned at the edge of the base plate 11. The straightening group 12 is located at the straightening station 4 to straighten the pin of the capacitor 9 clamped by the pneumatic clamp 8. The detection group 13 is located at the detection station 5 to detect the length of the PIN pin 10 of the capacitor 9 clamped by the pneumatic clamp 8. The driving end of the rotating motor 7 passes through the base plate 11 to position a group of horizontal cross-shaped positioning plates 14. The four groups of pneumatic clamps 8 are respectively positioned at the four ends of the cross-shaped positioning plate 14. The cross-shaped positioning A group of rotary joints 15 are also positioned in the center of the plate 14 through an arch frame, and the rotating end of the rotary joint 15 is installed on the cross-shaped positioning plate 14, and the fixed end of the rotary joint 15 is connected to the top of the base plate 11 through a bracket 16. The rotating end and the fixed end of the rotary joint 15 are connected by a transfer, and a connecting airway cavity is opened in the middle. The periphery of the rotating end is connected to the finger cylinder connecting ends of the four groups of pneumatic grippers 8 through four groups of rotary pipe joints, and the periphery of the fixed end is connected to the air source end through a fixed pipe joint. At this point, a relatively simple and neatly distributed connection structure is formed, which is also convenient for subsequent personnel maintenance.

[0034] The straightening group 12 includes a straightening cylinder 121 installed on the base plate 11 through a straightening mounting plate and a finger clamp 122 installed on the driving end of the straightening cylinder 121, the clamping center of the finger clamp 122 is located directly below the clamping end of the pneumatic clamp 8 rotated to the straightening station 4, when the pneumatic clamp 8 clamps the capacitor 9 and rotates to directly above the finger clamp 122, the straightening cylinder 121 pushes the finger clamp 122 upward, so that the two clamping ends of the finger clamp 122 are placed on both sides of the PIN pin 10, and then the finger clamp 122 clamps the end of the PIN pin 10, and is driven downward by the straightening cylinder 121 so that the PIN pin 10 with a serpentine bend can be straightened.

[0035] The clamping end of the pneumatic clamp 8 is provided with a right-angle groove 81 for receiving and positioning the shell of the capacitor 9. The end of the right-angle groove 81 is also provided with a blocking bar 82 for blocking the capacitor 9 in place. The two groups of right-angle grooves 81 of the pneumatic clamp 8 form a clamp for embracing the shell of the capacitor 9.

[0036] A set of pressing cylinders 17 are also connected to the bracket 16 through a connecting frame extending above the straightening station 4. The driving end of the pressing cylinder 17 is used to push the shell of the capacitor 9 into the right-angle groove 81, so as to avoid a gap between the bottom of the right-angle groove 81 and the capacitor 9 when the pneumatic gripper 8 grips the capacitor 9, thereby causing a shearing error during shearing.

[0037] The detection group 13 includes a driving cylinder 131 installed on the substrate 11, two sets of detection cylinders 132 installed on the driving end of the driving cylinder 131, and two pairs of metal probes 133 installed on the driving of the detection cylinders 132. The driving cylinder 131 is used to push the detection cylinders 132 so that the two pairs of metal probes 133 rise to both sides of the two sets of PIN pins, and the detection cylinders 132 are used to push the two pairs of metal probes 133 towards each other to contact the PIN feet 10 for electrical connection detection.

[0038] The shearing part 2 includes an X-direction cylinder 22 for installing an electric scissors 21 to move in the X direction, a Y-direction cylinder 23 for driving the X-direction cylinder 22 to move in the Y direction, and a Z-direction cylinder 24 for driving the Y-direction cylinder 23 to move in the Z direction. Therefore, after the PIN feet 10 of the capacitor 9 with qualified electrical connection detection move to the shearing station 6, the final shearing of the PIN feet 10 can be performed by the driving of the X-direction cylinder 22, the Y-direction cylinder 23, and the Z-direction cylinder 24.

[0039] Embodiment 2

[0040] As Figures 8-9As shown in the figure, a capacitance PIN foot trimming device, in this embodiment, is a further limitation based on Embodiment 1. Two sets of clamping ends of the finger gripper 122 are respectively drivingly connected with a set of spaced plates 124 through a set of horizontal push cylinders 123. The two sets of spaced plates 124 are arranged oppositely and horizontally between the finger gripper 122 and the pneumatic gripper 8. At the center of the end of one set of spaced plates 124, there is a partition 125 spaced between two PIN feet 10. The connecting end of the partition 125 and the corresponding spaced plate member is a smooth inclined surface 126 that flares away from the partition 125. At the center of the end of the other set of spaced plates 124, there is a slot 127 for inserting the partition 125, and the connecting end of the slot 127 and the corresponding spaced plate member is a smooth groove surface 128 that flares away from the slot 127. Thus, after the two clamping ends of the finger gripper 122 rise to both sides of the PIN foot 10, then drive the horizontal push cylinder 123 to push the spaced plate 124 to move. The flared smooth inclined surface 126 is used to expand the PIN foot 10 that bends inward to both sides, and the flared smooth groove surface 128 is used to narrow inward the PIN foot 10 that bends outward. Until the distance between the PIN feet 10 is the same as the distance between the connection roots of the PIN needles and the capacitor 9, then the clamping ends of the pneumatic finger gripper 122 clamp the ends of the PIN feet 10, and when pulled down by the straightening cylinder 121, the straightening of the PIN feet 10 can be realized;

[0041] At the bottom of the clamping end of the pneumatic gripper 8, there is also a set of positioning clips 84 driven by an electric push rod 83. The two pairs of positioning clips 84 of the pneumatic gripper 8 are arranged oppositely and are used to correspondingly abut against both sides of the root of the PIN needle. Thus, before the straightening operation, the electric push rod 83 can drive the positioning clips 84 to clamp the root of the PIN needle, and when the PIN foot 10 is straightened, the PIN needle will not be easily pulled off from the capacitor 9.

[0042] The working principle of the present invention is: A capacitance PIN foot trimming device provided by the present invention can continuously complete the operations of straightening, proofreading, and shearing the PIN needles of the capacitor 9 after the capacitor 9 is loaded, so as to eliminate the errors in the standards before shearing caused by the bending and positioning defects of the PIN needles, and improve the production accuracy of the capacitor 9;

[0043] When being straightened, that is, when the pneumatic gripper 8 holds the capacitor 9 and rotates to the position directly above the finger gripper 122, the straightening cylinder 121 pushes the finger gripper 122 upward, so that the two clamping ends of the finger gripper 122 are placed on both sides of the PIN foot 10. Then, the finger gripper 122 clamps the end of the PIN foot 10, and is driven downward by the straightening cylinder 121, so that the PIN foot 10 with a serpentine bend can be straightened. In order to further improve the straightening accuracy, a spacer plate 124 can be added. After the two clamping ends of the finger gripper 122 rise to both sides of the PIN foot 10, the horizontal push cylinder 123 is then driven to push the spacer plate 124 to move. The flared smooth inclined surface 126 is used to expand the PIN foot 10 bent inward to both sides, and the flared smooth groove surface 128 is used to narrow the PIN foot 10 bent outward inward. Until the distance between the PIN feet 10 is the same as the distance between the PIN pins and the connection root of the capacitor 9, then the clamping ends of the pneumatic finger gripper 122 clamp the ends of the PIN feet 10, and when being pulled down by the straightening cylinder 121, the straight-line straightening of the PIN feet 10 can be achieved.

[0044] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
