Description

Technical Field

[0001] The invention relates to the technical field of electric energy meter manufacturing, and in particular to a terminal box shaping and assembling device and an electric energy meter assembly line. Background Art

[0002] Single-phase electric energy meters are assembled with many parts. In the actual assembly process, many assembly processes need to be manually assembled by workers. For example, in the assembly of the terminal box (a component that carries the current copper bar and the voltage copper bar, and the current copper bar is welded with the metering device) and the bottom shell, during the operation, the worker needs to first put the terminal box into the bottom shell, and then knock it to make the protrusions on both sides of the terminal box match the slots on the terminal box. After a long period of assembly operation, the workers will become fatigued, which will not only reduce the assembly efficiency, but also easily damage the sampling pins on the terminal box or the bottom shell.

[0003] At the same time, the terminal box is equipped with pins for connecting to the PCB board of the metering device. During the hard connection process, the positioning accuracy of the pins is required. If they deviate a little, they may not be inserted smoothly into the PCB board. In the assembly process, from incoming materials to spot welding to terminal box assembly, many processes will affect the exposed pins, and some pins will deviate from the required size. This requires the operator to manually straighten them to ensure that the pins can be smoothly inserted into the PCB board. This manual straightening is inefficient and requires a high level of work experience from the operator during the straightening process, otherwise the pins are easily completely damaged.

[0004] In view of the above problems, it is urgently necessary to propose a device that can automatically press the terminal button box into the bottom shell and can automatically correct the pins on the terminal button box. Summary of the invention

[0011] In some specific embodiments, the terminal button box shaping assembly device also includes at least one buffer, which is installed on the press-fitting part, and the bottom end of the buffer is located below the press-fitting plane; wherein: when the press-fitting part moves downward under the drive of the press-fitting driving part, the buffer first contacts the terminal button box.

[0012] In some specific embodiments, the press-fitting part has a press-fitting protrusion, the lower surface of the press-fitting protrusion constitutes the press-fitting plane, and the press-fitting protrusion can stop at two pairs of sides of the terminal button box.

[0013] In some more specific embodiments, the press-fitting protrusion includes two first ribs spaced apart and a second rib connected between the two first ribs, and the two first ribs can stop at two opposite ends of the terminal box.

[0014] In some embodiments, the end button box shaping and assembly device is arranged in parallel with the transport line for transporting the bottom shell; the end button box shaping and assembly device also includes a stop mechanism and a position detection mechanism, the position detection mechanism is used to detect the position of the bottom shell, and the stop mechanism is configured to stop the bottom shell after the position detection mechanism detects the bottom shell.

[0015] In some more specific embodiments, the stop mechanism includes: a stop bracket, which is arranged in parallel with the transport line and connected to the fixed bracket; a stop cylinder, which is installed on the stop bracket, and after the position detection mechanism detects the bottom shell, the piston of the stop cylinder extends out and stops at the bottom shell.

[0016] In some more specific embodiments, the position detection mechanism includes: a detection bracket, one end of which is connected to the fixed bracket, and the other end of which extends vertically downward; a sensor, which is installed at the other end of the detection bracket, and in the transportation direction of the bottom shell, the sensor is located downstream of the stop mechanism.

When the bottom shell moves to the bottom of the press-fitting part under the drive of the transport line, the press-fitting driving part drives the press-fitting part to descend, and the press-fitting part can press the terminal button box into the bottom shell, and the correction hole can cooperate with the pins on the terminal button box to correct the pins. Since the more strenuous pressing process is automatically completed by the press-fitting part driven by the press-fitting driving part, the operating speed of the operator for a single product becomes faster, the production capacity is significantly improved, and the press-fitting part will not damage the pins on the terminal button box or the bottom shell when pressing the terminal button box, and the product quality is improved. In addition, since the additional correction part can correct the pins, the defective rate of the skewed pins is greatly reduced, the correction time for defective products is reduced, and the qualified rate of the pins is also significantly improved.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0034] The present invention discloses a terminal box shaping and assembling device, referring to Figure 1 and Figure 2 As shown, the terminal button box shaping assembly device includes a fixed bracket 10, a press-fitting driving member 11, a press-fitting member 12 and a correcting member 13. The press-fitting driving member 11 is installed on the fixed bracket 10, the press-fitting member 12 is connected to the press-fitting driving member 11, and can be lifted and lowered in the vertical direction under the drive of the press-fitting driving member 11. The correcting member 13 is connected to the press-fitting member 12, and the correcting member 13 has a plurality of correction holes 131 (such as Figure 5As shown). When the press-fitting driving member 11 drives the press-fitting member 12 to descend, the press-fitting member 12 can press the terminal button box into the bottom shell, and the correction hole 131 can cooperate with the pins on the terminal button box to correct the pins. First of all, it should be explained that in the actual assembly process, after the terminal button box is pre-installed into the bottom shell, the pre-installation method can be manually placing the terminal button box on the bottom shell transported by the transport line, or placing the terminal button box on the bottom shell transported by the transport line by a robot. It can be understood that when the bottom shell moves to the bottom of the press-fitting member 12, the press-fitting driving member 11 drives the press-fitting member 12 to descend, and the press-fitting member 12 can press the terminal button box into the bottom shell, and the correction hole 131 can cooperate with the pins on the terminal button box to correct the pins. Since the strenuous pressing process is automatically completed by the press-fitting part 12 driven by the press-fitting driving part 11, the operator's operation speed for a single product becomes faster, the production capacity is significantly improved, and the press-fitting part 12 will not damage the pins or the bottom shell on the terminal box when pressing the terminal box, so the product quality is improved. In addition, since the additional correction part 13 can correct the pins, the defective rate of crooked pins is greatly reduced, the correction time for defective products is reduced, and the qualified rate of pins is also significantly improved.

[0035] Optional, reference Figure 2-Figure 3 As shown, the press-fitting drive member 11 is a press-fitting cylinder, and the press-fitting member 12 is connected to the piston rod of the press-fitting cylinder through a first connecting member 17. Selecting a cylinder as the press-fitting drive member 11 can facilitate control and reduce costs. The connection between the press-fitting member 12 and the piston rod is achieved through the first connecting member 17, which can facilitate the connection and improve the installation stability of the press-fitting member 12, thereby ensuring that the press-fitting member 12 can stably press-fit the terminal box during actual work. The first connecting member 17 can be a bolt or a fixing pin, which can be selected according to actual needs. Further, refer to Figure 7 As shown, the terminal box shaping assembly device also includes a control box 22, which has a control module 23 for controlling the press-fitting cylinder and a time relay 24. The control module 23 can adjust the airflow size and control the movement speed of the press-fitting cylinder, and the time relay 24 controls and adjusts the time for the press-fitting cylinder to move back and forth, thereby achieving accurate press-fitting.

[0036] refer to Figure 3-Figure 4 As shown, the press-fitting part 12 has a mounting plane 121 and a press-fitting plane 122, and the press-fitting plane 122 is located below the mounting plane 121; the press-fitting plane 122 is used to press the terminal box, and the mounting plane 121 is used to install the correcting part 13. It can be understood that in the actual working process, when the press-fitting driving part 11 drives the press-fitting part 12 to descend, the correcting part 13 will contact the pins only after the press-fitting plane 122 contacts the terminal box, so that the press-fitting plane 122 first contacts the terminal box to press it into the bottom shell and then corrects the pins. The method of pressing first and then correcting is conducive to ensuring the correction accuracy, thereby reducing the defective rate of skewed pins.

[0037] Optional, reference Figure 3 As shown, the correcting piece 13 is fixed on the mounting plane 121 by the second connecting piece 18. The second connecting piece 18 is used to fix the correcting piece 13 on the mounting plane 121. On the one hand, it is convenient to install and remove the correcting piece 13, so that the correcting piece 13 can be easily replaced according to the correction needs. On the other hand, it can improve the installation stability of the correcting piece 13, thereby ensuring that the correcting piece 13 can stably correct the pins. The second connecting piece 18 can be a bolt or a fixing pin, which can be selected according to actual needs.

[0038] Optional, reference Figure 3-Figure 4 As shown, the terminal button box shaping assembly device also includes at least one buffer 14, and the buffer 14 is installed on the press-fitting part 12, and the bottom end of the buffer 14 is located below the press-fitting plane 122. When the press-fitting part 12 moves downward under the drive of the press-fitting drive part 11, the buffer 14 first contacts the terminal button box. It can be understood that the added buffer 14, on the one hand, buffers the downward pressure path of the press-fitting part 12 to protect the terminal button box and the bottom shell, and on the other hand, can separate the pins and the corrective part 13 more quickly during the rising process of the corrective part 13. The buffer 14 can be a hydraulic buffer device or a spring buffer device, and the specific type can be selected according to actual needs. In this embodiment, in order to ensure the buffering effect, the number of buffers 14 is two. In other embodiments of the present invention, the number of buffers 14 can be adjusted according to actual needs.

[0039] Optional, reference Figure 4 As shown, the press-fitting member 12 has a press-fitting protrusion 123, the lower surface of which constitutes a press-fitting plane 122, and the press-fitting protrusion 123 can stop against the two pairs of sides of the terminal button box. It can be understood that the clamping protrusions on the terminal button box are usually arranged on the two opposite sides of the terminal button box, and the press-fitting protrusions 123 can stop against the two pairs of sides of the terminal button box, so that the clamping protrusions on the terminal button box can be stably pressed into the clamping groove on the bottom shell during the pressing process of the press-fitting member 12, thereby ensuring that the terminal button box can be pressed into place.

[0040] Further optional, refer to Figure 4 As shown, the press-fitting protrusion 123 includes two first convex ribs 1231 spaced apart and a second convex rib 1232 connected between the two first convex ribs 1231, and the two first convex ribs 1231 can stop at two opposite ends of the terminal box. It can be understood that the U-shaped press-fitting protrusion 123 can make the pressure of the press-fitting protrusion 123 on the terminal box more uniform, thereby ensuring that the terminal box can be stably pressed into place, which is conducive to improving the assembly yield.

[0041] refer to Figure 6As shown, the correction hole 131 includes a tapered section 1311 and a straight section 1312, the straight section 1312 is connected to the small end of the tapered section 1311, and the large end of the tapered section 1311 is formed as an opening for the pin to be inserted. It can be understood that the large end of the tapered section 1311 is formed as an opening for the pin to be inserted, and the skewed pin will be guided into the correct position through the opening formed as a bell mouth, which is conducive to achieving correct correction of the pin.

[0042] refer to Figure 1 and Figure 2 As shown, the shaping and assembly device of the terminal button box is arranged in parallel with the transportation line for transporting the bottom shell; the shaping and assembly device of the terminal button box also includes a stop mechanism 15 and a position detection mechanism 16, the position detection mechanism 16 is used to detect the position of the bottom shell, and the stop mechanism 15 is configured to block the bottom shell after the position detection mechanism 16 detects the bottom shell. It can be understood that in the actual working process, during the transportation of the bottom shell on the transportation line, the operator or the manipulator can install the terminal button box on the bottom shell, and when the transportation line transports the bottom shell to the specified position, the position detection mechanism 16 can detect the bottom shell, and the position detection mechanism 16 can send a detection signal to the stop mechanism 15, and the stop mechanism 15 can block the bottom shell to keep it temporarily stationary. At this time, the pressing driving member 11 drives the pressing member 12 to descend, and the pressing member 12 can press the terminal button box into the bottom shell, and the correction hole 131 can cooperate with the pins on the terminal button box to correct the pins. In this way, the bottom shell is prevented from pressing and correcting the terminal button box during movement, which is conducive to improving the pressing and correction yield.

[0043] Optional, reference Figure 1-Figure 2 As shown, the position detection mechanism 16 includes a detection bracket 161 and a sensor 162. One end of the detection bracket 161 is connected to the fixed bracket 10, and the other end is vertically extended downward. The sensor 162 is installed at the other end of the detection bracket 161, and in the transportation direction of the bottom shell, the sensor 162 is located downstream of the stop mechanism 15. It can be understood that by installing the sensor 162 on the detection bracket 161, it can ensure that the sensor 162 is in a lower position, which is conducive to ensuring the detection accuracy of the sensor 162 and reducing the probability of misdetection of the sensor 162. Further optionally, one end of the detection bracket 161 has a bending portion, and the bending portion is connected to the fixed bracket 10 through the third connecting member 19, which facilitates the connection between the detection bracket 161 and the fixed bracket 10 on the one hand, and is conducive to improving the connection stability between the detection bracket 161 and the fixed bracket 10 on the other hand. The third connecting member 19 can be a bolt or a fixing pin, which can be selected according to actual needs. The sensor 162 can select an infrared sensor device or a photoelectric switch according to actual needs, and the specific type of the sensor 162 is not limited here.

[0044] Optional, reference Figure 1-Figure 2As shown, the stop mechanism 15 includes a stop bracket 151 and a stop cylinder 152. The stop bracket 151 is arranged in parallel with the transport line and is connected to the fixed bracket 10. The stop cylinder 152 is installed on the stop bracket 151. After the position detection mechanism 16 detects the bottom shell, the piston of the stop cylinder 152 extends and stops at the bottom shell. It can be understood that the stop bracket 151 can not only stop the cylinder 152, but also guide the bottom shell coming from the transport line to remain straight and not crooked, thereby facilitating the press-fitting of the press-fitted part 12. Further optional, refer to Figure 7 As shown, the terminal box shaping assembly device also includes a control box 22, which has a control module 23 and a time relay 24 for controlling the stop cylinder 152. The control module 23 can adjust the airflow size and control the movement speed of the stop cylinder 152. The time relay 24 controls and adjusts the time for the stop cylinder 152 to move back and forth. Thereby, accurate stopping is achieved. Of course, in other embodiments of the present invention, the stop mechanism 15 can also use an electric push rod, a motor-driven gear rack assembly, or a motor-driven ball screw to replace the stop cylinder 152.

[0045] Further optional, refer to Figure 2 As shown, the stop bracket 151 is connected to the fixed bracket 10 through an L-shaped connecting plate 154, and the connecting plate 154 includes a horizontal portion and a vertical portion, and the horizontal portion and the vertical portion are respectively connected to the fixed bracket 10 and the stop bracket 151 through the fourth connecting member 20. It can be understood that the connection between the stop bracket 151 and the fixed bracket 10 is achieved through the L-shaped connecting plate 154 and the fourth connecting member 20, which is conducive to ensuring the stability of the stop bracket 151, thereby ensuring the stability of the stop cylinder 152, and can also facilitate the assembly of the stop bracket 151. The fourth connecting member 20 can be a bolt or a fixing pin, which can be selected according to actual needs.

[0046] Further optional, refer to Figure 1 As shown, the stop cylinder 152 is connected to the stop bracket 151 through an L-shaped mounting plate 153, and the mounting plate 153 includes a first vertical plate and a second vertical plate, and the first vertical plate and the second vertical plate are respectively connected to the fixing bracket 10 and the stop bracket 151 through a third connecting member 19. The connection between the stop cylinder 152 and the stop bracket 151 is achieved through the L-shaped mounting plate 153 in conjunction with the fifth connecting member 21, which is conducive to ensuring the stability of the stop cylinder 152 and can also facilitate the installation and removal of the stop cylinder 152. The fifth connecting member 21 can be a bolt or a fixing pin, which can be selected according to actual needs.

[0047] The present invention also discloses an electric energy meter assembly line, including a transport line and the aforementioned terminal box shaping assembly device, wherein the transport line is used to transport the bottom shell, and the terminal box is placed on the bottom shell transported by the transport line manually or by a robot. It is understandable that in the actual assembly process, after the terminal box is pre-installed into the bottom shell, the pre-installation method can be to manually place the terminal box on the bottom shell transported by the transport line, or to place the terminal box on the bottom shell transported by the transport line by a manipulator, and when the bottom shell moves to the bottom of the press-fitting part 12 under the drive of the transport line, the press-fitting driving part 11 drives the press-fitting part 12 to descend, and the press-fitting part 12 can press the terminal box into the bottom shell, and the correction hole 131 can cooperate with the pins on the terminal box to correct the pins. Since the strenuous pressing process is automatically completed by the press-fitting part 12 driven by the press-fitting driving part 11, the operator's operation speed for a single product becomes faster, the production capacity is significantly improved, and the press-fitting part 12 will not damage the pins or the bottom shell on the terminal box when pressing the terminal box, so the product quality is improved. In addition, since the additional correction part 13 can correct the pins, the defective rate of crooked pins is greatly reduced, the correction time for defective products is reduced, and the qualified rate of pins is also significantly improved.
