[0044] The battery compartment assembly of consumer electronic products must be equipped with a negative spring and a spring cap. The negative spring has a large elastic coefficient, the assembly space of the battery compartment assembly is small, and the spring is generally irregular in shape, making assembly difficult. Most of the work in the industry is done manually, resulting in low assembly efficiency.

[0045] In order to solve the above problems, the present invention provides an assembly device. Figure 1 A three-dimensional schematic diagram of an embodiment of an assembly device provided by the present invention; Figure 2 for Figure 1A three-dimensional schematic diagram of the feeding mechanism; Figure 3 for Figure 2 Enlarged schematic diagram of point A in the middle.

[0046] See also Figures 1 to 3 The assembly device includes a machine base 1, a loading mechanism 2, a feeding mechanism 3 and a first assembly mechanism 4. The machine base 1 is provided with a loading station and a first assembly station; the loading mechanism 2 includes a picking part 21 for picking up the spring, and the picking part 21 is movably arranged and has a movable stroke between the loading station and the assembly station, and the picking part 21 is used to transport the spring at the loading station to the first assembly station; the feeding mechanism 3 includes a feeding device 31 and an adjusting component 32, and the adjusting component 32 is used to pick up the mounting cap provided by the feeding device 31, and adjust the mounting cap to a first preset posture and then place it at the first assembly station; the first assembly mechanism 4 is arranged corresponding to the first assembly station, and the first assembly mechanism 4 includes an extrusion mechanism 41, and the extrusion mechanism 41 is used to extrude the spring into the mounting groove of the mounting cap to form a spring cap.

[0047] In the technical solution provided by the present invention, the spring at the loading station is picked up by the material picking part 21 and placed at the first assembly station. The feeding device 31 provides mounting caps with different postures. The adjustment component 32 adjusts the mounting cap to a first preset posture that is preset for easy assembly, and then places it at the first assembly station. The extrusion mechanism 41 extrude and installs the spring at the first assembly station into the mounting groove of the mounting cap to form a spring cap, so that the special-shaped spring and the spring cap can be combined, and the degree of automation is high to solve the problem of low efficiency of manual assembly.

[0048] It should be noted that the mounting cap is configured as a cylinder with a flange, and a mounting groove is recessed at the end of one end where the flange is located. The spring has a first end and a second end that are arranged opposite to each other. The first end of the spring is a spring coil, and the second end of the spring is a non-circular special-shaped winding, and a negative electrode needle extends axially from the second end of the spring toward the first end of the spring.

[0049] Specifically, in this embodiment, the feeding device 31 includes a vibration plate 311 and a receiving portion 312. The vibration plate 311 is used to carry the mounting caps. The vibration plate 311 can be set to vibrate to adjust the mounting caps to a second preset posture. The vibration plate 311 is provided with a discharge port. The top of the receiving portion 312 is provided with a receiving trough. The receiving trough is provided corresponding to the discharge port and is used to receive the mounting caps output from the discharge port. By providing the vibration plate 311, the accumulated mounting caps are vibrated so that the mounting caps can be broken up and finally adjusted to the second preset posture. In the second preset state, the mounting caps are provided with one end of the flange facing downward. The receiving trough is provided in correspondence with the discharge port. When the vibration plate 311 vibrates, the mounting caps are sequentially extruded from the discharge port and sequentially transported into the receiving trough, and the second preset posture is always maintained.

[0050] Furthermore, in this embodiment, the vibration plate 311 and the material receiving portion 312 are arranged side by side with an interval in the transverse direction; it can be understood that the side of the material receiving trough close to the material discharge port passes through the material receiving portion 312, so that when the material receiving trough is aligned with the material discharge port, the mounting cap can be translated and input into the material receiving trough, so that the mounting cap can also maintain the second preset posture.

[0051] It should be noted that, since the discharge speed of the vibration plate 311 is relatively fast, and the subsequent assembly process takes a long time, in order to make better use of time and improve the material collection and assembly efficiency, in this embodiment, a plurality of material receiving troughs are provided, and the plurality of material receiving troughs are spaced apart in the longitudinal direction, and the material receiving portion 312 is movable along the longitudinal direction. With such a configuration, when the material receiving portion 312 moves along the longitudinal direction, the material receiving troughs on the material receiving portion 312 are aligned and connected with the discharge port one by one, and when each of the material receiving troughs is aligned with the discharge port, a mounting cap is output to the corresponding material receiving trough in the second preset posture, and during the entire longitudinal movement of the material receiving portion 312, each of the material receiving troughs receives and accommodates a mounting cap. With such a configuration, the efficiency of material collection can be improved.

[0052] Specifically, in order to facilitate the assembly of the spring and the mounting cap, the mounting cap needs to be adjusted to the first horizontal preset posture. In the first preset posture, the axial direction of the mounting cap is along the horizontal direction, and the notch of the mounting slot of the mounting cap needs to face the spring. However, on the receiving portion 312, the mounting cap is in the second preset posture, so the mounting cap needs to be further adjusted to the required posture. In this embodiment, the adjustment component 32 includes a mounting seat and an adjustment portion 321, and the mounting seat is fixedly mounted on the machine base 1; the adjustment portion 321 is used to pick up the mounting cap, and the adjustment portion 321 is rotatably mounted on the mounting seat. In this way, as needed, the adjustment portion 321 is controlled to flip 90°, so that the mounting cap picked up by the adjustment portion 321 is flipped and adjusted to the first preset posture, and placed at the first assembly station, so that the mounting cap meets the assembly posture requirements.

[0053] It should be noted that the end of the adjusting portion 321 is provided with a suction nozzle, which is connected to the negative pressure device. The adjusting portion 321 picks up the mounting cap by negative pressure suction. Of course, the method of picking up the mounting cap by the adjusting portion 321 is not limited to the above-mentioned negative pressure suction method, and can also be clamping, clamping, or magnetic suction, etc., which is not limited in the present invention.

[0054] Specifically, in this embodiment, the squeezing mechanism 41 includes two squeezing portions, which are spaced apart in the transverse direction and are respectively provided on either side of the mounting cap and the spring. The two squeezing portions can move relatively close to and away from each other in the transverse direction, and are used to squeeze the spring into the mounting groove of the mounting cap during the movement of approaching each other. It is understood that the two squeezing portions can be both movable, or one of the squeezing portions can move toward the other to squeeze.

[0055] Specifically, when the two extrusion parts are relatively close to each other, the spring will be subjected to axial force and deformed. However, when the spring is of a special shape, the force acting on the spring is not stable along its axial direction. Therefore, the spring may not be installed in the preset horizontal direction during compression, and there is a possibility of flying away. In this embodiment, one of the extrusion parts includes a positioning rod 411, and the other extrusion part includes a slider 412; the positioning rod 411 extends in the horizontal direction and is movable in the horizontal direction. During its horizontal movable travel, the spring is arranged around the periphery of the positioning rod 411. In this way, the positioning rod 411 exerts a radial constraint on the spring, so that the spring can only be compressed in the preset direction during compression. The slider 412 is slidably arranged in the horizontal direction. During its horizontal sliding travel, it is used to abut the mounting cap. By setting the slider 412 to abut the mounting cap and move in the horizontal direction, the mounting cap also has a travel toward the spring, so that the spring is finally squeezed into the mounting groove of the mounting cap. In this way, the spring is positioned by the positioning rod 411 and the assembly is supported by the slider 412, thereby improving assembly quality and efficiency.

[0056] Furthermore, to prevent the spring and mounting cap from rolling in the longitudinal direction when moving laterally, in this embodiment, the first assembly mechanism 4 also includes a bearing portion 42 for supporting the spring and mounting cap. The top of the bearing portion 42 is recessed with a contoured groove extending laterally. The contoured groove includes a first groove section 42a and a second groove section 42b that are connected in the laterally arranged manner. The first groove section 42a is for accommodating the spring, and the second groove section 42b is for accommodating the mounting cap. In this way, the first groove section 42a is adapted to the spring, and the second groove section 42b is adapted to the mounting cap. Through the first groove section 42a and the second groove section 42b, the mounting cap and the spring can be positioned relative to their respective circumferential sides, improving installation accuracy and preventing the spring from having difficulty aligning with the mounting groove.

[0057] Furthermore, to improve assembly efficiency, in this embodiment, a plurality of the profiling grooves, the positioning rods 411, and the sliders 412 are provided, with the plurality of profiling grooves spaced apart in the longitudinal direction. The extrusion mechanism 41 further includes a first drive device 43, a second drive device 45, a first connecting portion 44, and a second connecting portion. The first drive device 43 is fixedly mounted on the base 1 and includes a first drive portion that is movable in the transverse direction. The first connecting portion 44 is fixedly connected to the first drive portion so as to be driven to move in the transverse direction by the first drive portion. The first connecting portion 44 is longitudinally spaced apart and includes a plurality of the positioning rods 411. Thus, the first drive device 43 can simultaneously drive the plurality of positioning rods 411 to move in the transverse direction. The second drive device 45 is fixedly mounted on the base 1 and includes a second drive portion that is movable in the transverse direction. The second connecting portion is fixedly connected to the second drive portion so as to be driven to move in the transverse direction by the second drive portion. The second connecting portion is longitudinally spaced apart and includes a plurality of the sliders 412. In this way, the second driving device 45 can simultaneously drive multiple sliders 412 to move laterally. One positioning rod 411 and one slider 412 correspondingly squeeze one mounting cap and spring. In this way, with only two driving devices, multiple pairs of mounting caps and springs can be assembled, thereby improving the efficiency of the extrusion assembly.

[0058] Specifically, in this embodiment, the loading station and the first assembly station are spaced apart in the longitudinal direction; the assembly device further includes a third drive device 5 and a fourth drive device 6, the third drive device 5 being mounted on the machine base 1 and having a third drive portion that is movable in the longitudinal direction; the fourth drive device 6 being fixedly mounted on the third drive portion and having a fourth drive portion that is movable in the vertical direction, the fourth drive portion being fixedly connected to the material taking portion 21 to drive the material taking portion 21 to move up and down. The present invention does not limit the specific structure of the drive device, which may be a cam drive, a connecting rod drive, a screw structure, etc., and will not be described in detail here.

[0059] The assembly process of the assembly device is as follows:

[0060] First, a plurality of mounting caps are placed on the vibration plate 311, and the vibration plate 311 vibrates during operation to adjust the mounting caps to the second preset posture. The receiving portion 312 moves longitudinally and is in a state of waiting for material to be taken. After the mounting caps in the vibration plate 311 are adjusted to the second preset posture in turn, they are discharged in turn from the discharge port and transported toward the receiving portion 312 located on the side. When the receiving portion 312 moves longitudinally, when the receiving trough and the discharge port are aligned, the mounting caps are transferred to the receiving trough in turn. After the receiving portion 312 completes the material taking, the regulating portion 321 picks up the mounting caps in the second preset posture by negative pressure adsorption, and performs Flip so that the mounting cap is adjusted to the first preset posture, and the mounting cap is placed in the second groove section 42b; at the same time, the material picking part 21 picks up the spring that meets the installation posture from the loading station, and places the spring in the first groove section 42a. At this time, the first driving device 43 and the second driving device 45 are driven to work, so that the positioning rod 411 and the slider 412 move close to each other. When the positioning rod 411 moves, the spring is gradually sleeved on the periphery of the positioning rod 411, and the slider 412 pushes the mounting cap toward the spring until the first end of the spring is completely compressed and installed in the mounting groove of the mounting cap, thereby realizing the assembly of the spring cap.

[0061] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention.
