Description

Technical Field

[0001] This invention relates to the field of power fitting manufacturing technology, specifically to a power fitting assembly device and method. Background Technology

[0002] The bowl-shaped mounting plate requires the installation of W-shaped springs. The bowl end of the mounting plate has a groove, and the bottom of the groove has a locking hole for engaging the spring. The two free ends of the spring engage with the locking hole. The engaging groove of the spring faces outward from the groove and is used to engage with external hardware. The side of the groove has a slot for the external hardware to pass through. Since the initial distance between the two free ends of the W-shaped spring is larger than the size of the locking hole, the spring needs to be squeezed to reduce the distance between the two free ends, insert it into the locking hole, and then spring back to form a locking state. However, this process needs to be completed within the groove with limited space. Currently, slender clamps are often used to clamp and squeeze the spring, and then insert it into the groove and lock it into the locking hole to complete the installation of the spring.

[0003] Chinese patent application (publication number CN102371555A) discloses a spring pin picker for a bowl-shaped hanging plate, which is a manually operated tool and difficult to adapt to the needs of mass production in factories. If the working process of the picker is simulated, when installing the spring using slender clamps, the clamping action requires high positioning accuracy of the spring. In addition, the bowl-shaped hanging plate is a casting, and the precision of its structure is relatively low. When the clamps move the spring to the bowl-shaped hanging plate, it is easy to deviate from the position of the locking hole, resulting in the spring not being installed properly and the assembly efficiency of the spring on the bowl-shaped hanging plate being low. Summary of the Invention

[0004] The purpose of this invention is to address the deficiencies of existing technologies by providing an electrical fitting assembly device and method. This method utilizes a pressing assembly for pre-pressing and secondary pressing, pushing a spring into the retaining hole of the workpiece's cup-end groove. A guide head is used to correct the posture of the pre-pressed spring, ensuring it is in a state conducive to pressing and guaranteeing a horizontal position during the pressing process. This improves pressing accuracy and efficiency, and solves the problem of low assembly efficiency between existing springs and cup-end plates.

[0005] The first objective of this invention is to provide an electrical fitting assembly device, which adopts the following solution:

[0006] include:

[0007] The conveying assembly includes a conveyor belt and positioning blocks installed at intervals on the conveyor belt. The positioning blocks are provided with positioning grooves to accommodate workpieces.

[0008] The correction assembly is equipped with a telescopic push rod, and the end of the push rod is equipped with a spherical guide head, which is used to simultaneously contact both sides of the spring mating groove from the side to correct the horizontal posture of the spring.

[0009] The press assembly includes a press component that reciprocates vertically. The press component is provided with a pressure plate and a press block at intervals. The pressure plate and the press block act on different positioning blocks. In the vertical direction, the gap between the pressure plate and the positioning block is smaller than the gap between the press block and the positioning hole.

[0010] Furthermore, in the direction of movement of the positioning block, the pressure plate is located upstream of the pressing block, and the bottom surface of the pressure plate forms a pre-pressing surface that contacts the spring from above; the bottom surface of the pressing block forms a pressing surface that contacts the spring and the end face of the workpiece from above.

[0011] Furthermore, the bottom surface of the pressure plate and the bottom surface of the pressing block form a stepped structure, and the vertical projections of the bottom surface of the pressure plate and the bottom surface of the pressing block respectively cover the end face of the corresponding workpiece bowl head.

[0012] Furthermore, the end of the push rod is connected to the guide head via a pressure post, the radius of which is larger than the radius of the guide head, so as to form a stepped structure at the position where the pressure post connects to the guide head.

[0013] Furthermore, the correction component is located on the side of the conveyor belt, and the range of motion of the push rod is different from the range of motion of the pressing component.

[0014] Furthermore, it also includes a feeding assembly, which includes a displacement mechanism and a clamp. The clamp has a clamping part that adapts to the opening end of the spring mating groove. The clamp is mounted on the frame through the displacement mechanism.

[0015] Furthermore, the feeding assembly also includes a vibratory feeding mechanism, the output end of the vibratory feeder of the vibratory feeding mechanism is connected to the conveyor rail, and the displacement mechanism drives the clamp to move from the end of the conveyor rail to the top of the positioning block while holding the spring sheet.

[0016] Furthermore, the conveyor belt is a rotary structure, the pressing assembly is mounted above the conveyor belt, and a gap is left between the positioning groove and the side wall of the workpiece being carried to allow the workpiece to sway.

[0017] A second objective of the present invention is to provide a method for operating the power fitting assembly device as described in the first objective, comprising:

[0018] The positioning slot of the positioning block carries the workpiece to be assembled with the spring, and the workpiece moves under the drive of the positioning block and the conveyor belt;

[0019] Upstream of the press assembly, a spring with its free end facing downwards is inserted into the groove at the head end of the workpiece; the pressure plate pre-presses the spring in the groove at the head end, and the press block presses the pre-pressed spring;

[0020] As the conveyor belt runs, the push rod uses the guide head to squeeze the pre-compressed spring from the side, correcting the spring's posture so that the opening of the spring's mating groove faces the pressing block. The pressing block presses the spring so that the free end of the spring is locked into the locking hole at the end of the cup head. The push rod and the pressing block are then retracted.

[0021] The workpiece after pressing the spring is unloaded downstream of the pressing assembly.

[0022] Furthermore, the pressure plate presses down the spring, and after the guide head contacts one side of the spring mating groove, it drives the spring to move until both sides of the spring mating groove simultaneously abut the guide head, so that the opening of the mating groove faces upward for posture and position correction.

[0023] Compared with the prior art, the advantages and positive effects of this invention are:

[0024] (1) To address the problem that the W-shaped springs of the bowl head hanging plate workpiece are inconvenient to assemble, a pressing assembly is used for pre-pressing and secondary pressing. The springs are pushed into the clasp holes of the groove at the bowl head end of the workpiece. The guide head is used to correct the posture of the pre-pressed springs so that the springs are in a state that is easy to press and can ensure the horizontal position during the pressing process, thereby improving the pressing accuracy and pressing efficiency and solving the problem of low assembly efficiency between the existing springs and the bowl head hanging plate.

[0025] (2) By adjusting the vertical position of the spring through the pre-pressing action, the distance of the spring entering the groove is increased, ensuring that the guide head of the push rod can contact at least one side of the spring mating groove in the subsequent pressing process. This avoids the situation where the guide head cannot contact the spring for position and attitude correction due to the spring position being too high, thereby improving the pressing accuracy and efficiency.

[0026] (3) The positioning groove on the positioning block that accommodates the bowl head plate is slightly larger than the outer wall size of the bowl head plate, so that the bowl head plate can swing. During the movement, the spring is vibrated and corrected. At the same time, when the pressure plate is pre-pressed, it can promote the position adjustment of the spring, which helps the pressure plate to be pre-pressed and adjusted, and avoids the spring from getting stuck during pre-pressing, which can cause irreversible deformation.

[0027] (4) A rotary conveyor belt is used. After the conveyor belt drives the positioning block to complete the feeding, spring placement, pre-pressing, pressing and unloading process in sequence, the positioning block is transported to the feeding position through the return section to achieve continuous work and improve assembly efficiency.

[0039] Example 1

[0040] In a typical embodiment of the present invention, such as Figures 1-9 As shown, an electrical fitting assembly device is presented.

[0041] like Figure 1 and Figure 8 As shown, the bowl end 2 of the bowl head plate 1 needs to be fitted with a W-shaped spring 10. If it is installed from the side of the locking hole 4, the spring 10 needs to undergo a large deformation to allow one end of the mating groove 20 to pass through the locking hole 4. However, when the free end 19 of the spring 10 is inserted into the locking hole 4 from the side of the groove 3, the size of the groove 3 at the bowl end 2 makes it inconvenient to operate the spring 10, resulting in low installation efficiency of the spring 10 at the bowl end 2.

[0042] Based on this, this embodiment provides an electrical fitting assembly device, particularly for the workpiece 1, which can stably install the W-shaped spring 10 into the groove 3 of the bowl end 2 of the bowl end 1, and form a stable engagement with the locking hole 4 of the bowl end 2, thus meeting the workpiece assembly requirements. The following is a detailed description in conjunction with the accompanying drawings.

[0043] See Figure 2 The power fitting assembly device includes a conveying assembly 6, a correction assembly 15, and a pressing assembly 12. To meet material feeding requirements, a feeding assembly 9 is also included. Pre-pressing, secondary pressing, and posture correction are employed to improve pressing accuracy and efficiency. The conveying assembly 6 has a conveyor belt and positioning blocks 7 spaced along it. Positioning blocks 7 have positioning grooves 8 for accommodating workpieces. The conveyor belt and positioning blocks 7 in the conveying assembly 6 enable automatic conveying and precise positioning of the workpieces, ensuring a horizontal position during the pressing process. The pressing assembly 12 includes a vertically reciprocating pressing component. Pressure plates 13 and pressing blocks 14 are spaced along the pressing component, acting on opposite positioning blocks 7. Vertically, the gap between the pressure plate 13 and the positioning block 7 is smaller than the gap between the pressing block 14 and the positioning hole. Pre-pressing and secondary pressing using the pressing assembly 12 ensure that the spring 10 can accurately enter the locking hole 4 of the groove 3 at the cup end 2 of the workpiece. The correction assembly 15 is provided with a telescopic push rod 16, and the end of the push rod 16 is provided with a spherical guide head 18, which is used to simultaneously contact both sides of the spring plate 10 mating groove 20 from the side to correct the horizontal posture of the spring plate 10. Through the push rod 16 and the spherical guide head 18 in the correction assembly 15, the spring plate 10 is simultaneously contacted from the side to correct the horizontal posture of the spring plate 10, so that it is in a state that is easy to press-fit.

[0044] By employing posture correction and precise positioning, the position and posture of the reed 10 during the pressing process can be ensured to be accurate, thereby improving pressing precision. Automated conveying and positioning, along with an optimized pressing process, can significantly improve the assembly efficiency between the reed 10 and the bowl head plate 1, effectively solving existing problems.

[0045] In this embodiment, as Figure 2 As shown, the conveyor belt has a rotary structure, the pressing assembly 12 is mounted above the conveyor belt, and there is a gap between the positioning groove 8 and the side wall of the workpiece being carried, so that the workpiece can swing.

[0046] It should be noted that the positioning groove 8 on the positioning block 7 that accommodates the bowl head hanging plate 1 is slightly larger than the outer wall size of the bowl head hanging plate 1, so that the bowl head hanging plate 1 can swing. During the movement, the spring 10 is vibrated and corrected. At the same time, when the pressure plate 13 is pre-pressed, it can promote the position adjustment of the spring 10, which helps the pressure plate 13 to be pre-pressed and adjusted, and avoids the spring 10 from getting stuck during pre-pressing, which would cause irreversible deformation.

[0047] Among them, such as Figure 5 As shown, the conveyor belt of the conveyor assembly 6 is a rotary conveyor belt, and the positioning block 7 rotates and runs in a cycle following the conveyor belt. The upper part of the conveyor belt is the working section, and the lower part of the conveyor belt is the return section. At one end of the working section is the loading station, where the workpiece without spring 10 is placed in the positioning groove 8 of the positioning block 7. The spring 10 to be installed is conveyed to the cup end 2 of the workpiece in the positioning groove 8. The middle part of the working section is the pre-pressing station and the pressing station. The pre-pressing station is located upstream of the pressing station. The pressure plate 13 pre-presses and adjusts the position and posture of the spring 10 at the pre-pressing station, and the pressing block 14 presses the spring 10 at the pressing station so that the spring 10 is inserted into the locking hole 4. The other end of the working section is the unloading station. After the spring 10 is pressed, the workpiece is removed from the positioning groove 8 to complete the unloading. The positioning block 7 moves back to the loading station under the drive of the return section.

[0048] like Figure 4 As shown, in the moving direction of the positioning block 7, the pressure plate 13 is located upstream of the pressing block 14, and the bottom surface of the pressure plate 13 forms a pre-pressing surface that contacts the spring 10 from above; the bottom surface of the pressing block 14 forms a pressing surface that contacts the spring 10 and the end face of the workpiece from above.

[0049] The main structure of the pressing assembly 12 that acts on the workpiece and the spring 10 is the pressing component. The pressing component performs the pressing action through vertical reciprocating motion. The reciprocating motion of the pressing component can be achieved by configuring a linear reciprocating motion mechanism such as a cylinder or an electric cylinder. In this embodiment, a cylinder is used as an example. One end of the cylinder is mounted on the frame, and the other end is connected to the pressing component, so that the pressing component is suspended below the cylinder. The cylinder extends and retracts in the vertical direction to perform the vertical reciprocating motion required by the pressing component. Of course, when using an electric cylinder, the output end of the electric cylinder can also be connected to the pressing component to drive the pressing component to reciprocate in the vertical direction.

[0050] The bottom surfaces of the pressure plate 13 and the pressing block 14 form a stepped structure, and their vertical projections cover the end faces of the corresponding workpiece bowl end 2. The gap between the pressure plate 13 and the positioning block 7 is smaller than the gap between the pressing block 14 and the positioning hole, ensuring that the pre-pressing distance of the pressure plate 13 on the spring 10 is less than the pressing distance of the pressing block 14 on the spring 10. This achieves the function of pre-pressing and adjusting while avoiding damage to the spring 10 caused by excessive advancement.

[0051] The pressing component is equipped with a pressure plate 13 and a pressing block 14, which correspond to the actions of two different positioning blocks 7. The pressure plate 13 corresponds to the positioning block 7 located upstream, and can squeeze the spring 10 in the bowl head hanging plate 1 on the positioning block 7, adjust the vertical position of the spring 10 in the groove 3 of the bowl head hanging plate 1, and complete the pre-pressing action of the spring 10.

[0052] It should be noted that the pressure plate 13 and the pressure block 14 on the pressing component simultaneously perform vertical reciprocating motion. The pressure plate 13 performs a pre-pressing action, the purpose of which is to adjust the vertical position of the spring 10 in the groove 3 of the cup head hanging plate 1, preventing the spring 10 from being positioned too high, thus avoiding problems with correction and positioning in the subsequent pressing process. After adjusting the vertical position of the spring 10, the distance that the spring 10 enters the groove 3 is increased, ensuring that in the subsequent pressing process, the guide head 18 of the push rod 16 can contact at least one side of the spring 10 mating groove 20, avoiding the situation where the spring 10 is positioned too high, preventing the guide head 18 from contacting the spring 10 for position and attitude correction, thereby improving pressing accuracy and efficiency.

[0053] The purpose of pre-pressing the spring 10 by the pressure plate 13 is to adjust the position of the spring 10 so that the spring 10 initially enters the groove 3 of the bowl head hanging plate 1, so that the end of the push rod 16 can contact the spring 10. If the spring 10 is not pre-pressed, the position of the spring 10 will be higher than the position after pre-pressing, and the end of the push rod 16 will be below the spring 10 and cannot contact the spring 10. If the height of the push rod 16 is directly increased, the push rod 16 will interfere with the pressing block 14. The pressing block 14 will apply a radial force to the push rod 16, causing the push rod 16 to deform and damage the push rod 16.

[0054] The distance between the two free ends 19 is greater than the diameter of the locking hole 4, which makes it impossible for them to lock together on their own. Both free ends 19 need to be squeezed by the inner wall of the groove 3 to undergo elastic deformation, so that the two free ends 19 shrink and the distance between them can be reduced before entering the locking hole 4. This requires that the W-shaped spring 10, when pressed, needs to contact the pressing block 14 on both sides of the mating groove 20 at the same time. The opening of the mating groove 20 of the spring 10 needs to face directly upward, and the protrusions 21 on both sides of the mating groove 20 need to be at the same height so that they can contact the pressing block 14 at the same time. In this embodiment, after the spring 10 is placed into the groove 3 of the bowl end 2 of the bowl head plate 1, the spring 10 is often in an inclined position, the opening of the mating groove 20 is not fixed, and the protrusions 21 on both sides of the mating groove 20 are also in non-equal height positions, which causes the pressing block 14 to form an unbalanced squeeze on the spring 10, expanding the unbalanced position of the spring 10. After one free end 19 of the spring 10 enters the card hole 4, the other free end 19 cannot smoothly enter the card hole 4, making it difficult to achieve precise pressing.

[0055] In order to ensure that the spring 10 is accurately inserted into the card hole 4 by the action of the pressing block 14, in this embodiment, the correction component 15 is used to straighten the pre-pressed spring 10, ensuring that the spring 10 is in the state where the opening of the mating groove 20 is facing upward. The protrusions 21 on both sides of the mating groove 20 can simultaneously receive the squeezing action of the pressing block 14, reducing the offset during the pressing process and improving the pressing accuracy and pressing efficiency.

[0056] like Figure 5 , Figure 6 and Figure 7 As shown, the end of the push rod 16 is connected to the guide head 18 via a pressure post 17. The radius of the pressure post 17 is larger than the radius of the guide head 18, forming a stepped structure at the connection point. The push rod 16 passes through the slot 5 of the bowl-shaped hanging plate 1 and extends into the groove 3, causing the guide head 18 to contact the spring 10. Wherein, as... Figure 9 As shown, the end of the push rod 16 is a correction head, which includes a guide head 18 and a pressure post 17 continuously distributed along the axial direction of the push rod 16. The guide head 18 is a spherical crown-shaped protrusion, corresponding to the V-shaped cross section of the mating groove 20. The guide head 18 has a smooth structure. When the guide head 18 offsets and contacts the edge of the mating groove 20, the mating groove 20 is offset and subjected to force after one side contacts the guide head 18, causing the other side of the mating groove 20 to also approach and contact the guide head 18. The spherical crown-shaped smooth curved surface on the guide head 18 can push the mating groove 20 to move under the squeezing force of the push rod 16, so that the center line of the mating groove 20 approaches the axis of the guide head 18, thereby achieving the alignment of the spring 10 and the push rod 16. The guide head 18 is installed on the push rod 16 through the pressure post 17. The diameter of the pressure post 17 is larger than the diameter of the guide head 18, which is used to limit the axial position of the guide head 18 to prevent the guide head 18 from getting stuck in the mating groove 20.

[0057] The correction assembly 15 is located on the side of the conveyor belt, and the movement range of the push rod 16 is separate from that of the pressing assembly 12, to prevent the pressing block 14 of the pressing assembly 12 from damaging the correction assembly 15. It is understood that the push rod 16 can be driven by a cylinder, electric cylinder, etc. Taking a cylinder as an example, the end of the cylinder rod is connected to the guide head 18 and the pressure column 17. The guide head 18 is a hemispherical surface, and the diameter of the hemispherical surface is larger than the distance between the two sides of the mating groove 20, that is, larger than the width of the mating groove 20.

[0058] It should be noted that the spring 10 is pre-pressed by the pressure plate 13 to achieve the initial adjustment of the spring 10 in the vertical position; the spring 10 is pushed from the horizontal direction by the push rod 16 and positioned in the horizontal direction by the inner wall of the groove 3 to achieve the horizontal position correction, thereby correcting the vertical and horizontal posture of the spring 10 before the pressing action and ensuring the smooth progress of the pressing process.

[0059] like Figure 1 As shown, it also includes a feeding assembly 9, which includes a displacement mechanism 11 and a clamp. The clamp has a clamping part that adapts to the opening end of the groove 20 of the spring 10. The clamp is mounted on the frame via the displacement mechanism 11. The feeding assembly 9 also includes a vibratory feeding mechanism. The output end of the vibratory feeder of the vibratory feeding mechanism is connected to the conveyor rail 22. The displacement mechanism 11 drives the clamp to move from the end of the conveyor rail 22, clamping the spring 10, to above the positioning block 7. Figure 3 As shown, the vibratory feeder can use existing finished equipment. There are two conveying rails 22, which are placed in the guide grooves 23 on both sides of the spring plate 10 mating groove 20 to facilitate the stable conveying of the spring plate 10.

[0060] The displacement component can be a three-axis robotic arm, and the clamp can be a pneumatic gripper. The gripper is driven by a cylinder and has a groove to engage the end of the spring 10, thus forming a stable clamp on the spring 10.

[0061] Example 2

[0062] In another typical embodiment of the present invention, such as Figures 1-9 As shown, a working method for an electrical fitting assembly device is presented.

[0063] Using the electrical fitting assembly device as described in Example 1, the following steps are included:

[0064] The positioning groove 8 of the positioning block 7 carries the workpiece to be assembled into the spring 10, and the workpiece moves under the drive of the positioning block 7 and the conveyor belt.

[0065] Upstream of the pressing assembly 12, a spring 10 with its free end 19 facing downward is inserted into the groove 3 of the bowl end 2 of the workpiece; the pressure plate 13 pre-presses the spring 10 in the groove 3 of the bowl end 2, and the pressing block 14 presses the pre-pressed spring 10.

[0066] As the conveyor belt runs, the push rod 16 uses the guide head 18 to squeeze the pre-compressed spring 10 from the side, correcting the posture of the spring 10 so that the opening of the spring 10 mating groove 20 faces the pressing block 14. The pressing block 14 presses the spring 10 so that the free end 19 of the spring 10 is inserted into the locking hole 4 of the cup end 2. The push rod 16 and the pressing block 14 are then withdrawn.

[0067] The workpiece after pressing the spring 10 is unloaded downstream of the pressing assembly 12.

[0068] In addition, the pressure plate 13 presses down the spring 10, and the guide head 18 contacts one side of the spring 10 mating groove 20 and drives the spring 10 to move until both sides of the spring 10 mating groove 20 simultaneously abut the guide head 18, so that the opening of the mating groove 20 faces upward for posture and position correction.

[0069] In this embodiment, during the correction process of the correction component 15 on the spring 10, the guide head 18 is a spherical protrusion corresponding to the V-shaped cross-section of the mating groove 20. The guide head 18 has a smooth structure. The push rod 16 passes through the slot 5 of the bowl-shaped hanging plate 1 and enters the groove 3, so that the guide head 18 contacts the spring 10. When the guide head 18 deviates and contacts the edge of the mating groove 20, the mating groove 20 is offset after one side contacts the guide head 18, causing the other side of the mating groove 20 to also approach and contact the guide head 18. The spherical protrusion on the smooth curved surface of the guide head 18 can push the mating groove 20 to move under the squeezing force of the push rod 16, so that the center line of the mating groove 20 is close to the axis of the guide head 18, thereby achieving the centering of the spring 10 and the push rod 16. The guide head 18 is installed on the push rod 16 through the pressure column 17. The diameter of the pressure column 17 is larger than the diameter of the guide head 18, which is used to limit the axial position of the guide head 18 to prevent the guide head 18 from getting stuck in the mating groove 20.

[0070] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

7. The power fitting assembly device as described in claim 1, characterized in that, The conveyor belt is a rotary structure, and the pressing assembly is mounted above the conveyor belt. A gap is left between the positioning groove and the side wall of the workpiece being carried to allow the workpiece to sway.

8. A method for operating the power fitting assembly device as described in any one of claims 1-7, characterized in that, include: The positioning slot of the positioning block carries the workpiece to be assembled with the spring, and the workpiece moves under the drive of the positioning block and the conveyor belt; Upstream of the press assembly, a spring with its free end facing downwards is inserted into the groove at the head end of the workpiece; the pressure plate pre-presses the spring in the groove at the head end, and the press block presses the pre-pressed spring; As the conveyor belt runs, the push rod uses the guide head to squeeze the pre-compressed spring from the side, correcting the spring's posture so that the opening of the spring's mating groove faces the pressing block. The pressing block presses the spring so that the free end of the spring is locked into the locking hole at the end of the cup head. The push rod and the pressing block are then retracted. The workpiece after pressing the spring is unloaded downstream of the pressing assembly.

9. The working method of the power fitting assembly device as described in claim 8, characterized in that, The pressure plate presses down the spring, and after the guide head contacts one side of the spring mating groove, it drives the spring to move until both sides of the spring mating groove simultaneously abut the guide head, so that the opening of the mating groove faces upward for posture and position correction.
