Description

Technical Field

[0001] This invention relates to the field of electrical instrument manufacturing technology, and in particular to rapid packaging equipment and methods for the assembly and production of electrical instruments. Background Technology

[0002] Electrical instruments refer to various devices used to measure and monitor the parameters and operating status of power systems. They are an important component of power systems and are widely used in power generation, transmission and distribution, and power consumption. They play an indispensable role in ensuring the safe and stable operation of the power grid and the effective utilization of energy.

[0003] During the production process, electrical instruments require the connection of their housing and back cover. If gaps appear between the housing and back cover during the connection, the sealing performance of the electrical instrument will decrease, allowing external moisture to enter the instrument through the gaps, damaging the internal electronic components, and causing the instrument to malfunction or malfunction.

[0004] For example, in the prior art, there is an electrical instrument packaging structure and packaging equipment disclosed in CN118175783A. Although the packaging equipment uses glue and bolt connection to achieve the sealing connection of the electrical instrument housing, the lack of corresponding feeding and positioning structure during the packaging process makes it difficult to achieve automatic feeding and unloading before and after packaging. In addition, the packaging equipment cannot achieve multi-level positioning and fixing effect on the housing during the packaging process. As a result, the accuracy and efficiency of glue application and pressing operations need to be improved, which affects the overall expected packaging efficiency and quality. To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide rapid packaging equipment and methods for the assembly and production of electrical instruments, in order to solve the aforementioned technical defects.

[0006] The objective of this invention can be achieved through the following technical solution: a rapid packaging equipment for electrical instrument assembly production, including a base, on the top two sides of the base respectively, a housing conveying platform and a capping conveying platform are respectively installed, and a conveyor belt is rotatably connected to both the housing conveying platform and the capping conveying platform, and a positioning component is installed, and a feeding pressing component is provided on the base in conjunction with the positioning component; The positioning component includes a rotating seat, on which a stop rod and an auxiliary rod are fixedly connected. A push plate is slidably connected between the stop rod and the auxiliary rod. A positioning clamping plate is hinged to the push plate via a second spring telescopic rod. The feeding pressing component includes a lifting plate, on which negative pressure suction cups are connected to the bottom sides via support rods.

[0007] Preferably, a glue-applying robot and a screw-tightening robot are installed on the top of the base on the side of the housing conveyor away from the capping conveyor.

[0008] Preferably, both the housing conveying platform and the capping conveying platform are fixedly connected to a fixed seat, and a rotating rod that rotates with the corresponding rotating seat is rotatably installed on the fixed seat. A torsion spring is installed between the rotating seat and the fixed seat. Three sets of positioning components are provided on the housing conveying platform, and two adjacent rotating rods are fixedly connected.

[0009] Preferably, a gear and a winding wheel are fixedly connected to the rotating rod, and a convex groove is provided on the fixed seat, and a toothed plate that meshes with the gear is slidably connected in the convex groove.

[0011] Preferably, a plurality of guide blocks 1 are fixedly connected to the push plate, and a number of guide blocks 2 equal to the number of guide blocks 1 are fixedly connected to the positioning clamp plate, and the guide blocks 2 slide relative to the inclined surfaces of the guide blocks 1.

[0012] Preferably, a fixed cylinder is fixedly connected to the top of the base, and a hollow column that is fixedly connected to the lifting plate is slidably connected inside the fixed cylinder. A drive block is rotatably installed at the bottom of the hollow column, and a lead screw that is threadedly connected to the drive block is rotatably connected to the fixed cylinder. A motor for driving the lead screw to rotate is bolted on the base.

[0013] Preferably, the two outer walls of the drive block are connected to a linkage seat via a connecting block, and the linkage seat is provided with a clearance groove. The two inner walls of the clearance groove are provided with Z-shaped linkage grooves, and the toothed plate is equipped with a guide pin that cooperates with the Z-shaped linkage groove.

[0014] Preferably, vertical guide grooves are symmetrically provided on the inner walls of both sides of the fixed cylinder, and oblique guide grooves are provided between the vertical guide grooves. A guide protrusion is connected in the vertical guide groove and above the bottom of the oblique guide groove. A spring pin that cooperates with the vertical guide groove is installed on the hollow column.

[0015] This invention also proposes a rapid packaging method for the assembly and production of electrical instruments, which includes: conveyor-type preliminary positioning, positioning and clamping of the electrical instrument housing and cover, positioning and adhesive application, pressing and screw connection.

[0016] The beneficial effects of this invention are as follows: (1) In this invention, several electrical instrument housings and covers are first conveyed at the same speed and distance by the conveyor table.

Combined with the first spring telescopic rod, the stop rod is first made to change from a vertical state to a horizontal state, and the electrical instrument housing and cover are initially positioned. Then the push plate is made to move the positioning clamping plate to realize the secondary elastic clamping of electrical instrument housings of different sizes and models and the matching cover, thereby achieving the positioning treatment before gluing, pressing and screw connection. In addition, during the clamping process, the positioning clamping plate is driven to move closer to the stop rod, thereby assisting the electrical instrument housing or cover to contact the stop rod for further contact and further improve the positioning effect.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1-8 As shown, the following solutions can be used to address the problems in existing technologies, such as the difficulty in achieving automatic feeding and unloading before and after packaging, the inability to perform multi-process synchronous processing, and the resulting reduction in packaging efficiency. The rapid packaging equipment for electrical instrument assembly production in this embodiment includes a base 1. A housing conveying platform 11 and a cover conveying platform 12 are respectively installed on the top two sides of the base 1. The cover conveying platform 12 and the base 1 can be connected by multiple electric telescopic rods to adjust the height of the cover conveying platform 12, so as to facilitate the packaging of electrical instrument housings of different heights. Conveyor belts 13 are rotatably connected to both the housing conveying platform 11 and the cover conveying platform 12. The housing conveyor 11 and the cap conveyor 12 respectively convey several electrical instrument housings and caps at the same speed and at equal distances, realizing automatic feeding of electrical instrument housings and caps before packaging, and automatic conveying and unloading of housings after packaging. By simplifying the processing steps before and after packaging, the packaging efficiency is further improved. A positioning component 2 is installed to fix the electrical instrument housings and caps during the packaging process. A feeding and pressing component 3 linked with the positioning component 2 is set on the base 1 to realize the feeding and transfer of the caps and drive the caps to descend to complete the pressing process. The positioning component 2 includes a rotating seat 21, and a stop bar 22 and an auxiliary bar 23 are fixedly connected to the rotating seat 21. When the stop bar 22 is in a horizontal state, it can block and restrict the forward movement of the electrical instrument housing or cover during the movement process, and complete the initial positioning process. When the stop bar 22 is in a vertical state, it can cause multiple electrical instrument housings or covers to continue to move with the rotation of the conveyor belt 13, and complete the subsequent packaging and unloading process. A push plate 24 is slidably connected between the stop bar 22 and the auxiliary rod 23. A positioning clamp 26 is hinged to the push plate 24 via a second spring telescopic rod 25. The push plate 24, in conjunction with the second spring telescopic rod 25, carries the positioning clamp 26 to move and contact the electrical instrument housing or cover. Combined with the inner sidewalls of the housing conveying platform 11 and the cover conveying platform 12, the secondary positioning of the electrical instrument housing and the cover is completed. The feeding pressing assembly 3 includes a lifting plate 31, and the bottom sides of the lifting plate 31 are connected to negative pressure suction cups 32 by support rods. By rotating and lifting the lifting plate 31, the two sets of negative pressure suction cups 32 alternately grab the caps while simultaneously performing the pressing process of the previous cap.

[0021] On the top of the base 1, on the side of the housing conveying platform 11 away from the capping conveying platform 12, there is a glue-applying robot 14 and a screw-tightening robot 15. The glue-applying robot 14 is set up to automatically complete the glue-applying process of the glue tank of different models of electrical instrument housings through an external control system. The screw-tightening robot 15 is set up to install screws with multiple threaded holes on the pressed housing through an external control system, and can adapt to screw connections in different positions, further improving the packaging range.

[0022] Both the housing conveying platform 11 and the cap conveying platform 12 are fixedly connected to a fixed seat 27, and a rotating rod that rotates with the corresponding rotating seat 21 is rotatably installed on the fixed seat 27. A torsion spring 28 is installed between the rotating seat 21 and the fixed seat 27. Three sets of positioning components 2 are provided on the housing conveying platform 11. A set of positioning components 2 is provided on the capping conveyor 12, and the positioning components 2 and the positioning components 2 located in the middle of the housing conveyor 11 are on the same horizontal line. Through the cooperation of the four sets of positioning components 2, the electrical instrument housing before glue application, the electrical instrument housing after glue application, the electrical instrument housing after pressing, and the cap can be clamped and fixed simultaneously. The housing conveying platform 11 and the cap conveying platform 12 respectively convey several electrical instrument housings and caps at the same speed and at equal distances. The first electrical instrument housing and the second cap are conveyed at the same level, so that when the first cap is picked up in the early stage of operation, the first electrical instrument housing is simultaneously coated with glue, avoiding the problem of not being able to complete the sealing of the first electrical instrument housing. Furthermore, the two adjacent rotating rods are fixedly connected.

[0023] A fixed cylinder 33 is fixedly connected to the top of the base 1, and a hollow column 34 fixedly connected to the lifting plate 31 is slidably connected inside the fixed cylinder 33. A drive block 35 is rotatably installed at the bottom of the hollow column 34. A lead screw 36 threadedly connected to the drive block 35 is rotatably connected to the fixed cylinder 33. A motor 37 for driving the lead screw 36 to rotate is bolted on the base 1. The motor 37 drives the lead screw 36 to rotate. During the process of the lead screw 36 driving the drive block 35 to descend through the hollow column 34 and carrying the lifting plate 31, a negative pressure suction cup 32 on one side precisely adsorbs and grasps the cover, and the cover grasped by the negative pressure suction cup 32 on the other side contacts the electrical instrument housing directly below to complete the pressing process.

[0024] The two outer walls of the drive block 35 are connected to the linkage seat 38 through the connecting block. The fixed cylinder 33 is provided with a sliding groove that passes through the corresponding connecting block. The connecting block can prevent the drive block 35 from rotating with the screw 36 and restrict the drive block 35 to only perform lifting and lowering movements. The linkage seat 38 is provided with a clearance groove. The inner walls of the clearance groove are provided with Z-shaped linkage grooves 39. The toothed plate 211 is equipped with a guide pin 217 that cooperates with the Z-shaped linkage groove 39.

[0025] Vertical guide grooves 310 are symmetrically provided on the inner walls of both sides of the fixed cylinder 33, and oblique guide grooves 311 are provided between the vertical guide grooves 310. A guide protrusion 312 is connected in the vertical guide groove 310 and above the bottom of the oblique guide groove 311. A spring pin 313 that cooperates with the vertical guide groove 310 is installed on the hollow column 34. During the process of the driving block 35 carrying the lifting plate 31 down through the hollow column 34, the spring pin 313 on the hollow column 34 slides in the vertical guide groove 310, which restricts the rotation of the lifting plate 31. During the process of the negative pressure suction cup 32 descending to grab the cap, the glue-applying robot 14 simultaneously injects sealant into the first fixed electrical instrument housing glue-applying tank. Then, when the hollow column 34 is carried upward by the drive block 35, the spring pin 313 is guided by the guide protrusion 312, causing the spring pin 313 to enter the inclined guide groove 311, which in turn drives the lifting plate 31 to rotate 180°, so that the grabbed cap is moved to the top of the housing conveyor table 11, automatically completing the alternating use of the negative pressure suction cup 32. Following the subsequent descent of the lifting plate 31, while applying glue, the cover and the glued electrical instrument housing are pressed together. Simultaneously, the negative pressure suction cup 32 on the other side grips the cover. After pressing, the electrical instrument housing before glue application, the electrical instrument housing after glue application, the electrical instrument housing after pressing, and the cover are fixed in sync. During the pressing process, the glue application robot 14 and the screw tightening robot 15 simultaneously perform the glue application before pressing and the screw installation after pressing of the electrical instrument housing, thereby achieving simultaneous processing of multiple processes and improving packaging efficiency.

[0026] Example 2: Please refer to Figures 3-6 As shown, the following solutions can be used to address the problem that the inability to provide multi-level positioning and fixation of the outer shell results in a need to improve the accuracy and efficiency of the gluing and pressing operations. In this embodiment, both the housing conveying platform 11 and the cap conveying platform 12 are fixedly connected to a fixed seat 27, and a rotating rod that rotates with the corresponding rotating seat 21 is rotatably mounted on the fixed seat 27. A torsion spring 28 is installed between the rotating seat 21 and the fixed seat 27, which is used to cause the rotating seat 21 to reset and flip when the stop rod 22 is in a horizontal state and the force is released. Three sets of positioning components 2 are provided on the housing conveying platform 11, and two adjacent rotating rods are fixedly connected. There is no need to set corresponding toothed plates 211 and gears 29 on the fixed seats 27 on both sides of the housing conveying platform 11. The synchronous rotation effect of multiple rotating seats 21 can be achieved by the interconnection between multiple rotating rods.

[0027] A gear 29 and a take-up wheel 210 are fixedly connected to the rotating rod. A convex groove is provided on the fixed base 27 for the stable and anti-slip connection of the toothed plate 211. The toothed plate 211, which meshes with the gear 29, is slidably connected in the convex groove. By moving the toothed plate 211 away from the conveyor table, the meshing gear 29 drives the rotating rod and the take-up wheel 210 to rotate.

[0028] A first spring telescopic rod 212 is connected between the end of the push plate 24 and the stop rod 22 to increase the resistance of the push plate 24 moving on the stop rod 22. The elastic resistance is greater than the torsional deformation force of the torsion spring 28. A through groove is provided on the stop rod 22, and a guide wheel 213 is rotatably connected inside the through groove. A pull rope 214 that is connected to the guide wheel 213 is connected between the push plate 24 and the winding wheel 210. The meshing gear 29 carries the rotating rod and the winding wheel 210 to rotate. Under the elastic resistance of the first spring telescopic rod 212, the rotating rod causes the winding wheel 210 to wind up the rope 214. The force exerted on the rope 214 is greater than the force exerted by the torsion deformation of the torsion spring 28, forcing the rotating seat 21 to rotate 90°. This causes the limiting block installed on the rotating seat 21 to contact the fixed seat 27, causing the vertical stop bar 22 to become horizontal. This completes the initial positioning of the electrical instrument housing conveyed on the housing conveying table 11 and the cap conveyed on the cap conveying table 12. After the deflected rotating seat 21 contacts the fixed seat 27, the rotating rod continues to rotate. At this time, the winding wheel 210 on the rotating rod winds up the pull rope 214, causing the push plate 24 to overcome the elastic resistance of the first spring telescopic rod 212 and carry the positioning clamp 26 to move and contact the electrical instrument housing or cover. Combined with the inner sidewalls of the housing conveying platform 11 and the cover conveying platform 12, the secondary positioning of the electrical instrument housing and the cover is completed.

[0029] Multiple guide blocks 215 are fixedly connected to the push plate 24, and guide blocks 216 of the same number as guide blocks 215 are fixedly connected to the positioning clamp plate 26, and guide blocks 216 slide relative to the inclined surfaces of guide blocks 215. When the positioning clamp 26 contacts the electrical instrument housing or cover, the continuous movement of the push plate 24 compresses the second spring telescopic rod 25. Combined with the relative sliding of the inclined surfaces of the guide block 216 and the guide block 215, the positioning clamp 26 moves towards the stop rod 22, thereby assisting the electrical instrument housing or cover to further fit with the stop rod 22, improving the initial positioning effect, and completing the positioning and clamping of the electrical instrument housing and cover.

[0030] The two outer walls of the drive block 35 are connected to the linkage seat 38 through the connecting block, and the linkage seat 38 is provided with a clearance groove. The two inner walls of the clearance groove are provided with Z-shaped linkage grooves 39. The tooth plate 211 is equipped with a guide pin 217 that cooperates with the Z-shaped linkage groove 39. The screw 36 drives the drive block 35 to move downward with the two linkage seats 38. The guide pin 217 on the tooth plate 211 enters the inclined section from the lower vertical section of the Z-shaped linkage groove 39, thereby driving the tooth plate 211 to move away from the fixed seat 27, causing the meshing gear 29 to rotate with the rotating rod. After the deflected rotating seat 21 contacts the fixed seat 27, as the drive block 35 carries the two side linkage seats 38 in a continuous downward movement, the guide pin 217 on the toothed plate 211 continues to slide in the inclined section of the Z-shaped linkage groove 39, causing the rotating rod to continue to rotate, thus completing the movement of the push plate 24 carrying the positioning clamp 26. As the drive block 35 moves downward, the guide pin 217 on the toothed plate 211 enters the vertical section above from the inclined section of the Z-shaped linkage groove 39 to maintain the positioning and clamping effect. After the electrical instrument housing and the cover are positioned and clamped, the negative pressure suction cup 32 on one side performs precise adsorption and gripping of the cover, while the negative pressure suction cup 32 on the other side drives the cover and the electrical instrument housing to perform precise docking and pressing. The drive block 35 carries the lifting plate 31 to move upward. The guide pin 217 is guided by the Z-shaped linkage groove 39, which causes the toothed plate 211 to move back to its original position. The positioning clamp 26 and the push plate 24 are reset in sequence. Under the torsional elastic force of the torsion spring 28, the rotating seat 21 carries the stop bar 22 back to its original position. The housing conveying platform 11 and the cover conveying platform 12 continue to transport several electrical instrument housings and covers at equal distances.

[0031] Example 3: Please refer to Figures 1-8 As shown, the present invention also proposes a rapid packaging method for electrical instrument assembly and production, comprising the following steps: Step 1: Preliminary positioning by conveyor, specifically including the following process: The housing conveyor 11 and the cover conveyor 12 respectively convey several electrical instrument housings and covers at the same speed and at equal distances, with the first electrical instrument housing and the second cover being conveyed at the same level. The motor 37 drives the lead screw 36 to rotate, and the lead screw 36 drives the drive block 35 to carry the linkage seats 38 on both sides to move downward. The guide pin 217 on the toothed plate 211 enters the inclined section from the vertical section below the Z-shaped linkage groove 39, thereby driving the toothed plate 211 to move away from the fixed seat 27, causing the meshing gear 29 to carry the rotating rod to rotate. Under the elastic resistance of the first spring telescopic rod 212, the rotating rod forces the rotating seat 21 to rotate 90°, and drives the torsion spring 28 to twist and deform, so that the vertical stop bar 22 becomes horizontal, and performs preliminary positioning of the electrical instrument housing conveyed on the housing conveyor 11 and the cover conveyed on the cover conveyor 12. Step 2: Positioning and clamping of the electrical instrument housing and cover, specifically including the following process: After the deflected rotating seat 21 contacts the fixed seat 27, as the drive block 35 carries the continuous downward movement of the linkage seats 38 on both sides, the guide pin 217 on the toothed plate 211 continues to slide in the inclined section of the Z-shaped linkage groove 39, causing the rotating rod to continue to rotate. At this time, the winding wheel 210 on the rotating rod winds up the pull rope 214, causing the push plate 24 to overcome the elastic resistance of the first spring telescopic rod 212 and carry the positioning clamp 26 to move and contact the electrical instrument housing or cover. Combined with the inner sidewalls of the housing conveying table 11 and the cover conveying table 12, the secondary positioning of the electrical instrument housing and cover is completed. And after the positioning clamp 26 contacts the electrical instrument housing or cover, the continuous movement of the push plate 24 compresses the second spring telescopic rod 25, and combined with the relative sliding of the inclined surfaces of the guide block 216 and the guide block 215, the positioning clamp 26 moves closer to the stop rod 22, thereby assisting the electrical instrument housing or cover to further fit with the stop rod 22, improving the initial positioning effect, and completing the positioning and clamping of the electrical instrument housing and cover; Step 3: Positioning and gluing treatment, specifically including the following process: During the initial descent of the lifting plate 31 carried by the hollow column 34, the spring pin 313 on the hollow column 34 slides in the vertical guide groove 310, restricting the rotation of the lifting plate 31. The guide pin 217 on the toothed plate 211 enters the upper vertical section from the inclined section of the Z-shaped linkage groove 39 to maintain the positioning and clamping effect. After the electrical instrument housing and the cover are positioned and clamped, the negative pressure suction cup 32 on one side performs precise adsorption and gripping of the cover. The glue-applying robot 14 injects sealant into the glue-applying tank of the electrical instrument housing, and then the lifting plate 31 is raised by the drive block 35. The guide pin 217 is guided by the Z-shaped linkage groove 39, which causes the toothed plate 211 to reset. The positioning clamp 26 and the push plate 24 are reset in sequence. The rotating seat 21 is reset by the torsional elastic force of the torsion spring 28, and the stop bar 22 is reset. The housing conveying table 11 and the cover conveying table 12 continue to transport several electrical instrument housings and covers at equal distances. Step 4: Pressing process, which includes the following steps: During the upward movement of the hollow column 34, the spring pin 313 is guided by the guide protrusion 312, causing the spring pin 313 to enter the inclined guide groove 311, thereby driving the lifting plate 31 to rotate 180°, so that the gripped cover moves to the top of the housing conveyor table 11. The above process is repeated to position and clamp the electrical instrument housing and the cover again, and simultaneously position and clamp the electrical instrument housing after applying glue. As the lifting plate 31 moves downward, the cover and the electrical instrument housing after applying glue are pressed together while applying glue. Step 5: Screw connection, specifically including the following process: After pressing, repeat the above operation to simultaneously position and clamp the electrical instrument housing before glue application, the electrical instrument housing after glue application, the electrical instrument housing after pressing, and the cover. During the pressing process, the glue application robot 14 and the screw tightening robot 15 simultaneously perform the steps of applying glue to the electrical instrument housing before pressing and installing screws after pressing.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
