Description

Technical Field

[0001] This invention relates to the field of electronic device assembly technology, and more particularly to an assembly device. Background Technology

[0002] Currently, with the development of equipment, people are increasingly concerned about the size of electronic devices, which has led to a decrease in the size of the battery compartments of electronic devices.

[0003] To further reduce the size of the battery compartment, a housing with a mounting slot has been designed. The mounting slot needs to accommodate a compressed negative spring and a negative cap fitted onto the negative spring. To further reduce the size of the housing, the opening of the mounting slot is designed to be relatively small, which greatly increases the difficulty of assembling the negative cap first and then the negative spring. The original assembly process of assembling the negative cap first and then the negative spring can no longer meet the assembly requirements. That is, the later-installed components in the multi-stage assembly may not be able to fit into the mounting slot, and the assembly process of assembling the negative cap first and then the negative spring is not conducive to improving assembly efficiency.

[0004] In view of this, there is a need to develop an assembly device that can simultaneously press the assembly of the negative electrode cap and the negative electrode spring into the mounting groove on the workpiece. Summary of the Invention

[0041] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0042] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the 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 the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0043] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] This invention provides an assembly device that, by optimizing the installation structure, can assemble the negative electrode spring and negative electrode cap onto the workpiece in one go, eliminating the need for multiple installations. This improves installation efficiency and helps reduce the volume of the battery compartment housing.

[0045] Please see Figures 1 to 11 The assembly equipment includes:

[0046] The first picking robot 11 is used to pick up the negative electrode spring 100 and place it on the positioning block 21; the second picking robot 12 is used to place the negative electrode cap 200 on the mounting block 22; wherein the first picking robot 11 and the second picking robot 12 can be mounted on the same support arm, and the support arm can move horizontally to realize picking up and putting down materials.

[0047] Assembly module 2 includes a support plate, a positioning block 21 mounted on the support plate to support the negative electrode spring 100, a mounting block 22 with a sliding groove 221 to limit the negative electrode cap 200, a first lifting rod 23 mounted in the sliding groove 221 to support the negative electrode cap 200, and a pushing device 24 for pushing the positioning block 21 along the sliding groove 221 to engage one end of the negative electrode spring 100 in the hole of the negative electrode cap 200. The positioning block 21 is provided with a supporting sliding groove 101 for supporting the negative electrode spring 100. The positioning block 21 can press against the mounting block 22 under the push of the pushing device 24, so that the sliding groove 221 forms a mounting sliding hole. It should be noted that the end of the sliding hole aligns with the mounting groove of the workpiece, and the mounting groove is not smaller than the sliding hole. Preferably, the opening of the mounting groove matches the shape of the opening of the sliding hole.

[0048] Assembly module 2 also includes a linear module 25 for driving the support plate to move from the material handling station to the assembly station and a lifting device 26 mounted on the support plate to drive the first lifting rod 23 to lift along the mounting sliding hole. The first lifting rod 23 is also fixedly connected to a second lifting rod 27 for lifting the tail end of the negative pole spring 100 away from the positioning block 21.

[0049] The support fixture 3 is vertically mounted on the assembly station and has a positioning groove for positioning the workpiece. The support fixture is also provided with an assembly hole facing the assembly module 2.

[0050] The assembly steps are as follows:

[0051] ① The first material handling robot 11 picks up the negative electrode spring 100 and places it in the support groove 101 of the positioning block 21. The support groove 101 supports the negative electrode spring 100 and positions it at the same time. The support groove 101 allows the negative electrode spring 100 to slide upwards easily.

[0052] ② The second material handling robot 12 positions the negative electrode cap 200 in the sliding groove 221 of the mounting block 22, and the first lifting rod 23 supports the negative electrode cap 200; at this time, the negative electrode spring 100 and the negative electrode cap 200 are positioned respectively, and the extension direction of the negative electrode spring 100 is parallel to the blind hole of the negative electrode cap 200, and one end of the negative electrode spring 100 is directly opposite the blind hole of the negative electrode cap 200.

[0053] ③ The pushing device 24 is activated, causing the positioning block 21 and the mounting block 22 to move closer to each other. During the approach process, one end of the negative electrode spring 100 extends into the blind hole of the negative electrode cap 200. The negative electrode spring 100 and the negative electrode cap 200 are combined to form a combined body, and the main body of the negative electrode spring 100 is compressed in the mounting sliding hole.

[0054] ④ Driven by the lifting device 26, the first lifting rod 23 rises, pressing the assembly into the workpiece's mounting groove. When the assembly is pressed into the set position, the elastic force of the negative electrode spring 100 causes the negative electrode cap 200 to slide and be pressed into the positioning hole on the side wall of the negative electrode cap 200. During the sliding process of the negative electrode cap 200, the negative electrode spring 100 will simultaneously be driven into the mounting groove. It should be noted here that the second lifting rod 27 lifts the tail end of the negative electrode spring 100 away from the positioning block 21, thereby making the rise of the assembly during the assembly process more stable. Figure 7 , Figure 8 , Figure 9 As shown, the tail end of the negative spring 100, away from the positioning block 21, does not need to be pressed into the mounting groove of the workpiece. The second lifting rod 27 is used to improve the pressing quality.

[0055] In this embodiment, instead of installing the negative electrode spring 100 and negative electrode cap 200 in stages, the assembly is completed by pressing the assembly into the mounting slot in one go. This avoids the situation where subsequent components may not be able to be inserted into the mounting slot during staged assembly, and improves assembly efficiency. It should also be noted that the assembly equipment in this embodiment effectively improves the degree of automation in assembly.

[0056] Optionally, the assembly equipment includes a first feeding module, which includes a material tray with a groove for positioning the negative electrode spring 100. The first feeding module is located on one side of the first picking robot 11, which is equipped with a gripper 111 for clamping one end of the negative electrode spring 100 and a detection sensor 112 for detecting whether the negative electrode spring 100 is in the clamping position.

[0057] Optionally, the first picking robot 11 picks up the negative electrode spring 100 from the loading tray, and the detection sensor 112 detects whether the first picking robot 11 has accurately picked up the negative electrode spring 100. Finally, the first picking robot 11 transfers the negative electrode spring 100 into the supporting groove of the positioning block 21. In this embodiment, the negative electrode spring 100 includes a main body and an extended curved line portion. During assembly, it is only necessary to press the main body into the mounting groove.

[0058] Optionally, the assembly equipment includes a second feeding module, which includes a vibratory feeder 13, a discharge track connected to the vibratory feeder 13, and a material distribution mechanism located at the end of the discharge track away from the vibratory feeder 13. The material distribution mechanism is provided with a feeding position for feeding material to the second picking robot 12. The second picking robot 12 is provided with a contour suction head to pick up the negative electrode cap 200 in the feeding position, so as to better realize the feeding and assembly of the negative electrode cap 200.

[0059] Optionally, the positioning block 21 is also equipped with a telescopic device 28. The telescopic shaft of the telescopic device 28 is provided with a retaining rod 29 for extending into the center hole of the negative pole spring 100. The positioning block 21 is provided with a clearance hole to avoid the retaining rod 29. The center line of the retaining rod 29 is consistent with the center line of the negative pole spring 100, and the telescopic shaft is parallel to the retaining rod 29.

[0060] Specifically, after the negative spring 100 is positioned on the positioning block 21, the telescopic device 28 extends the retaining rod 29 into the center hole of the negative spring 100 to prevent the negative spring 100 from bending and deforming during assembly. After the compressed assembly is completed, the retaining rod 29 is pushed out in the opposite direction to avoid blocking the lifting action of the first lifting rod 23.

[0061] Optionally, the assembly equipment also includes an incoming material conveyor belt 4, on one side of which is an incoming material robot 5 for transferring workpieces from the trays of the incoming material conveyor belt 4 to the supporting fixture 3.

[0062] Optionally, the assembly equipment is also provided with an elastic pressing component 31 for pressing and positioning the workpiece in the positioning groove. After the workpiece is transferred to the set position of the support fixture 3, the elastic pressing component 31 presses the workpiece to prevent the first lifting rod 23 from pushing the workpiece out.

[0063] Optionally, the assembly equipment is also equipped with a discharge robot 6 for transferring the tray on the carrier fixture 3 to the incoming material conveyor belt 4.

[0064] Optionally, the assembly equipment also includes a flipping device 7: the flipping device 7 includes a workpiece clamping assembly and a flipping assembly; the workpiece clamping assembly is used to clamp the workpiece on the incoming conveyor belt 4, and the flipping assembly is used to drive the workpiece clamping assembly to flip 180°, and then place the workpiece in another positioning cavity of the carrier tray to prepare for subsequent processes.

[0065] Optionally, the assembly equipment also includes a photographic inspection module 8, which includes a detection CCD for photographing the workpiece and a ring light source for supplementary illumination. After the workpiece is rotated 180°, the installation positions of the mounting slot and the negative electrode spring 100 and negative electrode cap 200 in the mounting slot are more easily photographed for inspection and facilitate subsequent pressing inspection to check the installation quality.

[0066] Optionally, the assembly equipment is also equipped with a pressing detection module 9, which includes a single-axis manipulator and a pressing detection push rod mounted on the single-axis manipulator to press the negative pressure spring on the workpiece. A pressure detection sensor 112 is provided at the end of the pressing detection push rod. By detecting the magnitude of the pressing pressure, it can be determined whether the negative electrode spring 100 and the negative electrode cap 200 are assembled successfully.

[0067] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
