They primarily consist of a housing, terminal blocks, and circuit boards. The terminal block has raised or recessed terminals that are used for mating and electrical connection with other components. To accurately assemble the terminal block into the housing, the assembly method typically involves first fixing the housing, then sequentially inserting the terminal blocks into it. Specifically, this involves clamping the terminal blocks, moving them above the housing, and then pressing them down and placing them onto the housing.

[0029] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0030] In the description of this invention, it should be understood that the terms "top", "bottom", "inner", "outer", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] like Figures 1 to 7As shown, an assembly machine of the present invention includes a base 1, a fixing frame 2, a loading box 3, and a pressing assembly 4. The loading box 3 includes a box body 31 and a cover plate 32. The box body 31 is disposed on the top surface of the base 1 and has a receiving cavity inside for placing the housing of an electrical box. The top surface of the box body 31 has a top hole extending through the receiving cavity. The cover plate 32 is disposed on the top surface of the box body 31 and has a set of pressing holes 321 extending vertically. The pressing holes 321 are downwardly connected to the top hole and are used to engage terminal blocks. The fixing frame 2 includes fixing plates 21, which are spaced apart from the loading box. Above 3, the pressing assembly 4 includes a pressing driver 41, a pressing frame 42, and a plurality of pressing pins 43. The pressing frame 42 is slidably disposed on the fixing plate 21 in a vertical direction. The plurality of pressing pins 43 are vertically disposed on the pressing frame 42. Each pressing hole 321 corresponds to at least one pressing pin 43. The pressing driver 41 is disposed on the fixing plate 21 and connected to the pressing frame 42. The pressing driver 41 is used to drive the pressing frame 42 to move downward, so that the pressing pin 43 is inserted into the corresponding pressing hole 321, thereby causing the pressing pin 43 to press the terminal block in the corresponding pressing hole 321 downward into the housing of the electrical box.

[0033] In the above technical solution, the receiving cavity of the box body 31 is used to place the housing of the electrical box, and the cover plate 32 is provided on the top of the box body 31 of the electrical box, and is provided with a plurality of pressing holes 321 for snapping on the terminal board; further, the fixing plate 21 of the fixing frame 2 is spaced above the loading box 3, and is used to set the pressing assembly 4. Specifically, the pressing frame 42 of the pressing assembly 4 is movably arranged on the fixing plate 21 in the vertical direction, and a plurality of pressing pins 43 of the pressing assembly 4 are provided on the pressing frame 42, wherein one pressing hole 321 corresponds to at least one pressing pin 43, and the pressing of the pressing assembly 4 is... The driver 41 is connected to the pressing frame 42. The pressing driver 41 can drive the pressing frame 42 to move downward, so that the pressing pin 43 is inserted into the corresponding pressing hole 321, and then the pressing pin 43 presses the terminal board in the corresponding pressing hole 321 downward into the housing of the electrical box, realizing the function of assembling multiple terminal boards into the housing of the electrical box in one pressing operation. In summary, the present invention can assemble multiple terminal boards in one pressing operation, with high assembly efficiency and suitable for mass production. The terminal board can be locked in the pressing hole 321 by mating relationship and a certain degree of bending.

[0034] Furthermore, a set of pressure holes 321 includes a type of hole 3211, which is an elongated hole extending horizontally. The loading box 3 also includes a glass bead assembly 33. Each type of hole 3211 corresponds to at least one glass bead assembly 33. The glass bead assembly 33 includes a mounting spring and a contact glass bead 331. The hole wall of the type of hole 3211 is provided with a horizontal hole, which corresponds one-to-one with the glass bead assembly 33. The mounting spring is disposed in the horizontal hole, and its two ends are respectively connected to the bottom of the horizontal hole and the contact glass bead 331. The contact glass bead 331 protrudes from the wall of the first type of hole 3211 and is used to abut against the terminal plate. The first type of hole 3211 corresponds to the snap-fit ​​of the elongated terminal plate. This terminal plate has no bending part and is difficult to snap-fit ​​into the first type of hole 3211 by mating. Therefore, it is necessary to press and fix the terminal plate into the first type of hole 3211 by assembling a spring and the contact glass bead 331. Moreover, this fixing method puts less pressure on the terminal plate and will not cause too much resistance to the pressing operation of the pressing pin 43.

[0035] Furthermore, a set of pressure holes 321 includes two types of holes 3212, each type of hole 3212 including multiple branch holes extending in the horizontal direction, each branch hole being connected in sequence, and the extension directions of the connected branch holes having an angle between them; wherein, the type of holes 3212 are corresponding to the terminal plate with a bent portion, and the terminal plate can be directly engaged with the type of holes 3212 through its elastic deformation after bending; in addition, the glass bead assembly 33 can also be provided in the type of holes 3212 to more stably engage the terminal plate.

[0036] Furthermore, the minimum distance between adjacent pressure holes 321 is greater than 1.6mm. Although this may require the assembly of the terminal board to be divided into multiple steps, it can prevent the cover plate 32 from being too weak and causing it to break.

[0037] Furthermore, to prevent press-fitting when terminal blocks are already installed inside the electrical box housing, it is necessary to inspect the condition inside the electrical box housing before press-fitting. Since the terminal blocks will protrude from the electrical box housing through exposure holes on the side of the housing after press-fitting, it is possible to determine whether a terminal block is already installed inside the electrical box housing by detecting whether it passes through the exposure holes. The specific structure for this inspection is as follows: the side of the box body 31 has a detection hole extending into the receiving cavity. The assembly machine also includes a mistake-proofing detector, which includes a detection driver 91, a mounting block 92, a detection rod 93, a detection spring 95, and a first pressure sensor. The first pressure sensor is located on the detection driver 91, which is fixedly mounted on the box body 31. The detection driver 91 is connected to the mounting block 92, and the mounting block 92 is slidably connected to the detection rod 93. The outer wall of the detection rod 93 is provided with a boss 94. The detection spring 95 is sleeved on the outside of the detection rod 93. The two ends of the detection spring 95 abut against the mounting block 92 and the boss 94, respectively. The detection driver 91 is used to drive the mounting block 92 to move towards the receiving cavity, so that the detection rod 93 passes through the detection hole and is inserted into the receiving cavity. The positions of the detection hole and the exposed hole are corresponding. When a terminal plate passes through the exposed hole and the detection rod 93 is inserted into the receiving cavity to a specified depth, the detection rod 93 abuts against the side of the terminal plate, the detection spring 95 is compressed, the first pressure sensor detects the pressure, and it is determined that a terminal plate has been installed in the housing of the electrical box. The device alarms and stops the subsequent process. When the detection rod 93 is inserted into the receiving cavity to a specified depth, the detection rod 93 does not abut against any object, the detection spring 95 does not change, the first pressure sensor does not detect the pressure, it is determined that no terminal plate has been installed in the housing of the electrical box, and the process continues.

[0038] Furthermore, it also includes a slide rail 5 and a motion driver 6. The slide rail 5 extends in the front-back direction and is disposed on the bottom surface of the base 1. The loading box 3 also includes a slider 34, which is disposed on the bottom surface of the box body 31 and is slidably connected to the slide rail 5, allowing the loading box 3 to move in the front-back direction. The motion driver 6 is disposed on the base 1 and connected to the loading box 3. The motion driver 6 is used to drive the loading box 3 to move in the front-back direction to facilitate the replacement of the electrical box housing. The specific process is as follows: the moving driver 6 drives the loading box 3 to move out from under the pressing component 4, and the cover 32 with the empty pressing hole 321 and the assembled electrical box housing are taken out in sequence. Then, the electrical box housing without the terminal plate is placed in the receiving cavity, and the cover 32 with the terminal plate in the pressing hole 321 is placed on the box body 31. The moving driver 6 drives the loading box 3 to move to under the pressing component 4 and then performs the pressing operation. The moving driver 6 can be an electric slide rail 5.

[0039] Furthermore, it also includes a plate mounting detector 7, which is disposed downward on the side of the fixed plate 21 relative to the front-rear direction. When the loading box 3 is located below the plate mounting detector 7, the plate mounting detector 7 is used to detect whether each of the pressing holes 321 is equipped with a corresponding terminal plate. After the cover plate 32 with the terminal plate in the pressing hole 321 is placed on the box body 31, the plate mounting detector 7 checks once whether each pressing hole 321 on the cover plate 32 is equipped with a terminal plate. If each pressing hole 321 is equipped with a terminal plate, the operation continues; if any pressing hole 321 is missing a terminal plate, an alarm is triggered, and the assembly machine stops subsequent operations.

[0040] Furthermore, the box body 31 has multiple side holes extending into the receiving cavity. The assembly machine also includes multiple positioning actuators 8 corresponding to the side holes. Each positioning actuator 8 includes a positioning cylinder and a positioning rod. The positioning cylinder is fixedly mounted on the box body 31. The positioning cylinder can drive the positioning rod to move in the direction of the corresponding side hole, so that the positioning rod passes through the side hole and is inserted into the receiving cavity, thereby abutting against the housing of the electrical box. The positioning rods of the multiple positioning actuators 8 are used to abut against the housing of the electrical box from multiple directions. Specifically, two positioning rods can abut against the housing of the electrical box from two directions, so that the housing of the electrical box is pressed against the two cavity surfaces of the receiving cavity, thereby achieving the positioning and fixing of the housing of the electrical box.

[0041] Furthermore, the pressing driver 41 includes a pressing rod 411 and a pressing cylinder 412. The pressing cylinder 412 is fixedly disposed on the top surface of the fixing plate 21 and connected to the pressing rod 411. The pressing cylinder 412 is used to drive the pressing rod 411 to move vertically. The fixing plate 21 has a through hole in the vertical direction, through which the pressing rod 411 passes. The bottom end of the pressing rod 411 is connected to the pressing frame 42. The pressing assembly Component 4 also includes a plurality of slide rods 44, which are arranged around the press-in rod 411. The slide rods 44 are slidably connected to the fixed plate 21 in the vertical direction, and the bottom end of the slide rods 44 is connected to the first pressure plate 421 so that the press-in actuator 41 can stably and smoothly apply uniform pressure to the press-in frame 42. The press-in actuator 41 may be a piston cylinder. In addition, the top ends of each slide rod 44 may be connected to each other to enhance the stability of its structure and sliding action.

[0042] Furthermore, the pressing frame 42 includes a first pressing plate 421, a second pressing plate 422, and a third pressing plate 423 arranged sequentially from top to bottom. The first pressing plate 421, the second pressing plate 422, and the third pressing plate 423 are fixedly connected to each other. The pressing driver 41 is connected to the first pressing plate 421. The pressing assembly 4 also includes a pressing assembly 45 corresponding to the pressing needle 43. The pressing assembly 45 is disposed above the pressing needle 43. The pressing assembly 45 includes a pressing post 451 and a pressing spring 452. The pressing post 451 includes a post head 4511, a first post rod 4512, and a second post rod 4513 arranged sequentially from bottom to top. Plate 422 has multiple vertically penetrating lower column holes. The column head 4511 is located below the second pressure plate 422. The first column rod 4512 passes through the lower column holes. The compression spring 452 is sleeved on the outside of the first column rod 4512. The two ends of the compression spring 452 abut against the top surface of the column head 4511 and the bottom surface of the second pressure plate 422, respectively. The bottom surface of the second column rod 4513 abuts against the top surface of the second pressure plate 422. The press-in needle 43 includes a needle head 431 and a needle body 432 arranged sequentially from top to bottom. The third pressure plate 423 has multiple vertically penetrating needle holes. The needle body 432 passes through the needle holes. The needle head 431 is located below the second pressure plate 422. Above the third pressure plate 423, the bottom surface of the needle 431 is used to abut against the top surface of the third pressure plate 423; when the bottom end of the needle body 432 presses against the terminal plate, the bottom end of the column head 4511 presses against the top surface of the needle 431 to provide downward pressure on the needle body 432; wherein, during the process of the pressing driver 41 driving the pressing frame 42 to move downward, the pressing needle 43, the pressing assembly 45 and the terminal plate will perform the following actions in sequence: S1, the bottom end of the needle body 432 touches the top surface of the corresponding terminal plate; S2, the pressing needle 43 moves upward relative to the pressing frame 42; S3, the bottom surface of the column head 4511 contacts the top surface of the needle 431; S4, the pressing column 451 and the pressing needle 43 move upward relative to the pressing frame. 42 moves upward. During this process, the pressure spring 452 is compressed, and the pressure applied by the column head 4511 to the needle head 431 gradually increases. S5: When the pressure applied by the column head 4511 to the needle head 431 is large enough, the pressing needle 43 presses the terminal plate downward until it moves. The pressure column 451, the pressing needle 43, the pressing frame 42, and the terminal plate move downward together relatively fixedly. S6: When the terminal plate is pressed into place, the pressing driver 41 stops driving, and the pressure column 451, the pressing needle 43, the pressing frame 42, and the terminal plate all come to rest. In addition, when the pressing operation is completed, the pressing driver 41 drives the pressing frame 42 to move upward, and all components return to their positions. Furthermore, the needle head 431 is used to prevent the pressing needle 43 from disengaging downward from the needle hole.

[0043] Furthermore, the pressing frame 42 also includes an intermediate plate 424, which is disposed between the first pressure plate 421 and the second pressure plate 422. The intermediate plate 424 is fixedly connected to the second pressure plate 422. The pressing column 451 also includes a third column 4514 disposed at the top of the second column 4513. The intermediate plate 424 has a plurality of vertically penetrating upper column holes, and the third column 4514 is inserted into the corresponding upper column holes. The pressing assembly 45 also includes a positioning detector disposed on the top surface of the intermediate plate 424. The positioning detector is used to detect the position of the top of the third column 4514 to determine whether the corresponding pressing column 451 is pressed in place and whether sufficient pressure is provided. Specifically, the positioning detector can detect whether the third column 4514 protrudes beyond the specified position. The top surface of the intermediate plate 424 is used for judgment. When the third column 4514 protrudes from the top surface of the intermediate plate 424, it is judged that the pressing is in place. The position detector can also detect the distance of the third column 4514 protruding from the top surface of the intermediate plate 424 for judgment. When the distance of the third column 4514 protruding from the top surface of the intermediate plate 424 is within a certain distance range, it is judged that the pressing is in place. Furthermore, the pressing assembly 4 also includes a second pressure sensor. The second pressure sensor is located on the pressing driver 41. The second pressure sensor is used to detect the actual pressure of the pressing driver 41 on the pressing frame 42 to determine whether there is any abnormality in the component performing the pressing action. When the second pressure sensor detects that the actual pressure is greater than a certain value, the device alarms and the pressing driver 41 stops working until the inspection is completed before it resumes work.

[0044] Furthermore, the fixing frame 2 also includes a plurality of support columns 22, the two ends of which are respectively connected to the top surface of the base 1 and the bottom surface of the fixing plate 21.

[0045] Furthermore, the specific connection methods of fixed setting and fixed connection refer to the methods that can fix the relative positional relationship of two connected components, including fixing by connectors, fixing by welding, fixing by adhesive, fixing by integral molding, and fixing by snap-fit ​​connection.

[0046] Furthermore, a sliding connection refers to a connection between two components, where one component can slide along a fixed trajectory on the other component, including connection by sliding the slider 34 into a groove, or connection by inserting the slider 44 into a hole whose size and profile match the slider 44.
