Description

Technical Field

[0001] The present invention relates to an automatic assembly device, in particular to a highly integrated automobile camera bracket automatic assembly device applied to the field of automobile parts assembly. Background Art

[0002] This is mainly based on the automotive industry's rapid development demand for intelligent driving technology, as well as the urgent need to improve production efficiency, reduce costs and ensure product quality.

[0003] In the prior art, the assembly of a car camera bracket involves various small parts, which need to be assembled one by one on a manual assembly line. To improve assembly efficiency, automated machinery is later used for assembly line assembly. However, this method generally requires one part to form one assembly line, which not only causes the overall assembly equipment to occupy a large area, but also requires repeated loading and unloading of the bracket, which affects the assembly efficiency. In addition, mechanical equipment is prone to cumulative deviations when used for a long time, but the cumulative deviation is relatively small and difficult to detect. For the assembly of small parts, the small parts themselves are very small. Under the effect of cumulative deviations, it is easy for small parts to be difficult to be stably placed in the target position, affecting the assembly efficiency and the quality of the finished product after assembly. In severe cases, small parts may even fall off and not be assembled. Summary of the invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the method of assembling a single part in a self-assembled assembly line is inefficient, which affects the production efficiency of the product.

[0005] In order to solve the above problems, the present invention provides a highly integrated automatic assembly device for automobile camera brackets, including an equipment body with a control center, a multi-station turntable is installed in the middle of the upper end of the assembly platform of the equipment body through an electric turntable, the multi-station turntable is divided into four stations distributed in a circular array, each station is installed with a workpiece carrier, the automobile camera bracket to be assembled is clamped and placed on the workpiece carrier, along the rotation direction of the multi-station turntable, the assembly platform is sequentially provided with surrounding manipulators, buckle vibration loading trays, lens implantation modules, lens vibration loading trays and hot pressing modules, one of the stations is directly opposite to the front door of the equipment body, The remaining three workstations correspond to the surrounding manipulators, the lens implantation module and the hot pressing module respectively.

[0007] A workstation monitoring unit is arranged between the assembly platform and the multi-station turntable. The workstation monitoring unit includes a light receiving plate fixedly connected to the upper end of the equipment body, a laser emitter fixedly connected to the middle of the upper end of the light receiving plate, and an expansion differential light receiving hemisphere fixedly connected to the lower end of the multi-station turntable. The expansion differential light receiving hemisphere is located directly below the workstation facing the front end of the equipment body, and in the initial position, the expansion differential light receiving hemisphere and the laser emitter are coaxially arranged. The workstation monitoring unit also includes a secondary high-definition camera installed on the top of the equipment body, and the shooting end of the secondary high-definition camera faces the light receiving plate.

[0008] In the above-mentioned highly integrated automatic assembly equipment for the automotive camera bracket, multiple rotatable workstations and corresponding assembly modules are integrated in the same equipment. The automatic assembly of multiple parts is realized by rotating the multiple workstations. Compared with the assembly method of one part and one production line in the prior art, the floor space occupied by the assembly equipment is greatly reduced, and the number of loading and unloading times is effectively reduced, thereby effectively improving the assembly efficiency.

[0009] As a further improvement of the present application, the multi-station turntable rotates at an angle of 90° each time, and the shapes of the snap clamp and the lens clamp are consistent with the contours of the corresponding parts.

[0013] As another improved supplement of the present application, one end of the light-changing arc sheet extends outside the light-changing slot, and the other end of the light-changing arc sheet interferes with the connection between the light-through hole and the light-changing slot. The radius of the light-changing arc sheet is larger than the radius of the expansion sphere, and the vertical side length of the light-changing arc sheet is smaller than the horizontal side length.

[0014] A highly integrated automatic assembly device for a car camera bracket, wherein the method for using the station monitoring unit comprises the following steps:

[0015] S1. Every time the multi-station turntable rotates 360°, the laser transmitter is controlled to automatically start, so that the laser transmitter emits a laser beam toward the differential light-receiving hemisphere and irradiates the differential light-receiving hemisphere;

[0016] S2. When the multi-station turntable does not rotate and deviate, the laser beam is vertically directed to the differential light-receiving hemisphere and passes through the light hole to fall on the laser receiver. At this time, the reflected light coincides with the laser beam, and no laser spot is generated on the light-receiving plate.

[0017] S3. When there is a cumulative tolerance, the multi-station turntable rotates and deviates. At this time, the coaxiality between the differential light-receiving hemisphere and the laser emitter is destroyed. At this time, the emitted laser beam is not perpendicular to the surface of the differential light-receiving hemisphere, and the laser receiver cannot receive the laser light, thereby generating reflected light, and the reflected light falls on the light-receiving plate to generate an obvious laser light spot;

[0018] S4. At this time, the secondary high-definition camera obtains the image information and feeds the signal back to the control center. The control center controls the expansion ball to rotate 90° toward the laser point on the light-receiving plate according to the image information, so that the laser falls on the variable light arc sheet. Then the control center controls the variable light arc sheet to move back and forth horizontally, thereby continuously changing the reflection angle, so that the laser spot on the light-receiving plate changes continuously, thereby reminding the on-site staff who are loading or unloading materials, so as to detect abnormalities in time and shut down and perform maintenance.

[0019] In summary, multiple rotatable workstations and corresponding assembly modules are integrated in the same equipment, and the automatic assembly of multiple parts is realized by rotating the multiple workstations. Compared with the assembly method of one part and one production line in the prior art, the floor space occupied by the assembly equipment is greatly reduced, while the number of loading and unloading times is effectively reduced, and the assembly efficiency is effectively improved. In addition, with the setting of the workstation monitoring unit, the cumulative deviation caused by multiple rotations can be effectively detected. When this happens, the tiny cumulative deviation can be amplified and dynamically displayed, thereby effectively ensuring that the smaller cumulative deviation can be detected in time when it occurs, so that the staff can take corresponding measures to eliminate the deviation in time, further ensuring the assembly efficiency and the quality of the finished product.

DETAILED DESCRIPTION

[0037] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0038] The first implementation method:

[0039] Figure 1-2A highly integrated automatic assembly device for a car camera bracket is shown, in which a represents a car camera bracket to be assembled, comprising a device body 1 with a control center, a multi-station turntable 2 is installed in the middle of the upper end of the assembly platform of the device body 1 through an electric turntable, the multi-station turntable 2 is divided into four stations distributed in a circular array, each station is installed with a workpiece carrier 201, the car camera bracket to be assembled is clamped and placed on the workpiece carrier 201, along the rotation direction of the multi-station turntable 2, the assembly platform is sequentially provided with surrounding manipulators 3, buckle vibration loading tray 41, lens implantation module 5, lens vibration loading tray 42 and hot pressing module 6, one of the stations is directly opposite to the front end door of the device body 1, and the other three stations are respectively ... The surrounding manipulator 3, the lens implantation module 5 and the hot pressing module 6 correspond to each other. By integrating the surrounding manipulator 3, the buckle vibration loading tray 41, the lens implantation module 5, the lens vibration loading tray 42 and the hot pressing module 6 into one device, when in use, first place the bracket to be assembled at the station facing the front door of the equipment body 1, and then control the rotation of the multi-station turntable 2 by the electric turntable, so as to change the relative positions of multiple stations. After rotating 360 degrees, the bracket to be assembled on the same station is completely buckled and the lens is assembled. Compared with the prior art assembly method of one part and one production line, the assembly efficiency is effectively improved, and the floor space occupied by the automated assembly equipment is reduced, and more assembly equipment can be arranged in a limited space.

[0040] The multi-station turntable 2 rotates by 90° each time, so that the relative positions of the stations change the same after each rotation, so that the surrounding manipulators 3, the lens implantation module 5 and the hot pressing module 6 can be stably assembled under the movement of predetermined parameters.

[0041] It is also worth noting that, in the present embodiment, four workstations are provided. In specific implementation, a suitable number of workstations may be provided according to actual needs, and the angle of each rotation of the multi-station turntable 2 may be changed accordingly.

[0042] like Figure 3-Figure 5 , c in the figure represents a buckle, and a plurality of buckle clamps 31 are installed on the movable ends of the surrounding manipulators 3. A buckle linear guide 402 is also provided at the discharge end of the buckle vibration loading tray 41. The lower end of the buckle linear guide 402 is fixedly connected to the equipment body 1 through a bottom plate, and an electric cylinder 403 is fixedly connected to the upper end of the bottom plate. The extended end of the electric cylinder 403 is fixedly connected to a buckle transfer plate 71. The right end of the buckle transfer plate 71 close to the buckle linear guide 402 is fixedly connected to a baffle plate 72, and the baffle plate 72 contacts the end of the buckle linear guide 402. A plurality of accommodating grooves 701 are cut on the buckle transfer plate 71 toward one end of the buckle linear guide 402, and the accommodating grooves 701 match the internal slideway of the buckle linear guide 402;

[0043] like Figure 6 , b in the figure represents a lens, a discharge end of the lens vibration loading tray 42 is fixedly connected to a lens linear guide 404, a lens turntable 405 is arranged in front of the lens linear guide 404, and a bracket located on one side of the lens linear guide 404 is also fixedly connected to the upper end of the assembly platform, a main high-definition camera 43 is installed on the top of the bracket, and the shooting end of the main high-definition camera 43 faces the lens turntable 405, as shown in FIG. Figure 7-8 The lens implantation module 5 and the hot pressing module 6 both include an X-axis shift module 51, a Y-axis shift module 52 installed on the upper end of the X-axis shift module 51, and a Z-axis shift module 53 installed on the Y-axis shift module 52. The lower end of the Z-axis shift module 53 on the lens implantation module 5 is installed with a lens clamp 501 through an electric shaft. The angle and position of the lens on the lens turntable 405 can be obtained through the main high-definition camera 43. The control center can control the lens clamp 501 to rotate to a suitable angle to clamp the lens according to the signal, effectively ensuring that the lens is more stable during the transfer from the lens turntable 405 to the component bracket. At the same time, it also effectively ensures the accuracy of the lens assembly angle. The shapes of the snap clamp 31 and the lens clamp 501 are consistent with the contours of the corresponding parts, so that the two are not likely to cause damage to the parts when clamping the corresponding parts for assembly. The lower end of the Z-axis shift module 53 on the hot pressing module 6 is fixedly connected to the heating module 602, and the lower end of the heating module 602 is connected to the hot melt rod 601. After the lens is installed, as the multi-station turntable 2 rotates, the workpiece to be assembled moves to the hot pressing module 6. At this time, the position of the hot pressing module 6 is adjusted by the X, Y, and Z three-axis moving modules, so that the hot melt rod 601 contacts the lens on the to-be-assembled bracket for hot melting and fixing.

[0044] like Figure 9-10 A workstation monitoring unit is provided between the assembly platform and the multi-station turntable 2. The workstation monitoring unit comprises a light-receiving plate 81 fixedly connected to the upper end of the equipment body 1, a laser emitter 82 fixedly connected to the middle of the upper end of the light-receiving plate 81, and a differential expansion light-receiving hemisphere 9 fixedly connected to the lower end of the multi-station turntable 2. The differential expansion light-receiving hemisphere 9 is a hemispherical structure, and the differential expansion light-receiving hemisphere 9 is made of an opaque high-reflective material. The differential expansion light-receiving hemisphere 9 is located directly below the workstation facing the front end of the equipment body 1, and in the initial position, the differential expansion light-receiving hemisphere 9 is coaxially arranged with the laser emitter 82. When there is no cumulative tolerance, the differential expansion light-receiving hemisphere 9 is still coaxial with the laser emitter 82 after rotating one circle with the multi-station turntable 2, such as Fig.11In the figure, d represents the laser beam, and the dotted line represents the reflected light. With the emergence of cumulative tolerance, the expansion differential light-receiving hemisphere 9 gradually becomes non-coaxial with the laser emitter 82, so that the laser originally shot at the center of the expansion differential light-receiving hemisphere 9 and perpendicular to the surface of the expansion differential light-receiving hemisphere 9 is offset from the center. Due to the spherical surface of the expansion differential light-receiving hemisphere 9, the reflected light of the light that is not perpendicular to it is different everywhere, so the reflected light generated by the offset laser falls on the light-receiving plate 81, and the greater the offset amplitude, the greater the relative distance between the laser landing point and the laser emitter 82. Compared with the prior art where it is difficult to detect small deviations in time, the amplified display of the deviation is realized, and there is no need to wait until the cumulative tolerance accumulates to a certain extent before it can be discovered, which is convenient for timely maintenance and improves the stability and efficiency of automated assembly.

[0045] The workstation monitoring unit also includes a secondary high-definition camera installed on the top of the equipment body 1. The shooting end of the secondary high-definition camera faces the light receiving plate 81. The secondary high-definition camera can monitor the landing point of the laser beam at the light receiving plate 81, so as to timely detect the accumulated tolerance and feedback it to the control center.

[0046] The length of the light receiving plate 81 is greater than the diameter of the multi-station turntable 2, and the length of the light receiving plate 81 is not less than 1.5 times the diameter of the multi-station turntable 2, so that the length of the light receiving plate 81 is long enough, and then after the cumulative tolerance occurs, when the expanded light receiving hemisphere 9 moves with the station to the front end of the equipment body 1 and is misaligned with the laser emitter 82, the light reflected by the laser can fall on the light receiving plate 81, and then be monitored and detected in time, and it is not easy for the light to fail to fall on the light receiving plate 81.

[0047] In addition, the upper surface of the light receiving plate 81 is black. When the red laser falls on the light receiving plate 81, the contrast is relatively strong, which is easier to be captured by the high-definition camera and the staff. The upper surface of the light receiving plate 81 can also be selectively coated with laser color-changing material so that the laser reflected light can change color when it falls on its surface, thereby making the landing point display more obvious.

[0048] In summary, multiple rotatable workstations and corresponding assembly modules are integrated in the same equipment, and the automatic assembly of multiple parts is realized by rotating the multiple workstations. Compared with the assembly method of one part and one production line in the prior art, the floor space occupied by the assembly equipment is greatly reduced, while the number of loading and unloading times is effectively reduced, and the assembly efficiency is effectively improved. In addition, with the setting of the workstation monitoring unit, the cumulative deviation caused by multiple rotations can be effectively detected. When this happens, the tiny cumulative deviation can be magnified and displayed, thereby effectively ensuring that the smaller cumulative deviation can be detected in time when it occurs, so that the staff can take corresponding measures to eliminate the deviation in time, further ensuring the assembly efficiency and the quality of the finished product.

[0049] The second implementation method:

[0050] This embodiment further improves the differential expansion light receiving hemisphere 9 on the basis of the first embodiment, and the rest of the parts are consistent with the first embodiment.

[0051] Figure 12-14 As shown, the differential expansion light receiving hemisphere 9 includes a bearing plate 91 and a differential expansion ball 92 connected to the lower end of the bearing plate 91 through an electric rotating shaft, the bearing plate 91 is fixedly connected to the multi-station turntable 2, a light through hole 901 is drilled in the middle of the differential expansion ball 92, a laser receiver 94 is installed at the center of the bearing plate 91, and the laser receiver 94 is located in the light through hole 901. A light changing groove 902 is drilled at the outer end of the differential expansion ball 92 away from the front end of the equipment body 1, and the light changing groove 902 is communicated with the light through hole 901, and a light changing arc piece 93 is connected to the light changing groove 902 through an electric slide rail, one end of the light changing arc piece 93 extends to the outside of the light changing groove 902, and the other end of the light changing arc piece 93 conflicts with the connection between the light through hole 901 and the light changing groove 902. After the secondary high-definition camera captures the laser landing point generated at the light receiving plate 81, as shown in Fig.15 , the diffusion ball 92 can be controlled to rotate, so that the light-changing arc plate 93 is close to the laser beam, and the laser falls on the light-changing arc plate 93. When the position of the laser changes from the diffusion ball 92 to the light-changing arc plate 93, the landing point of the laser reflection changes rapidly. When the laser has fallen on the light-changing arc plate 93, the light-changing arc plate 93 can be controlled to move back and forth horizontally, so that the intersection between the laser and the light-changing arc plate 93 changes continuously, and then the laser landing point on the light-receiving plate 81 moves back and forth continuously, thereby presenting dynamic changes. Compared with the first embodiment, on the basis of amplifying the display of the cumulative tolerance, dynamic display can also be realized, which is convenient for on-site staff and the secondary high-definition camera to obtain the change in time, and the control center can preliminarily understand the amplitude of the cumulative tolerance according to the changes in light, so as to reduce the difficulty of subsequent maintenance.

[0052] The radius of the light-changing arc sheet 93 is greater than the radius of the differential expansion ball 92, so that the curvatures of the surfaces of the light-changing arc sheet 93 and the differential expansion ball 92 are different, so that the reflected light generated by the same beam of light on the differential expansion ball 92 and the light-changing arc sheet 93 is also different, and the vertical side length of the light-changing arc sheet 93 is less than the horizontal side length, so that the light-changing arc sheet 93 is relatively flatter. When the laser beam of the laser emitter 82 falls on the differential expansion ball 92, the angle of the reflected light obtained is relatively small, and the landing point displayed on the laser emitter 82 is closer to the laser emitter 82. When the light-changing arc sheet 93 moves back and forth to make the landing point constantly change, the landing point can be changed back and forth within a small range, which is easy to capture and makes the dynamic change phenomenon more obvious.

[0053] A highly integrated automatic assembly device for a car camera bracket, wherein the method for using the station monitoring unit comprises the following steps:

[0054] S1, every time the multi-station turntable 2 rotates 360°, the laser emitter 82 is controlled to automatically turn on, so that the laser emitter 82 emits a laser beam toward the differential light-receiving hemisphere 9 and irradiates the differential light-receiving hemisphere 9;

[0055] S2, when the multi-station turntable 2 does not rotate and deviate, the laser beam is vertically directed to the differential light-receiving hemisphere 9 and passes through the light hole 901 and falls on the laser receiver 94. At this time, the reflected light coincides with the laser beam, and no laser spot is generated on the light-receiving plate 81;

[0056] S3, when there is a cumulative tolerance, the multi-station turntable 2 rotates and deviates, and the coaxiality between the differential expansion light receiving hemisphere 9 and the laser emitter 82 is destroyed. At this time, the emitted laser beam is not perpendicular to the surface of the differential expansion light receiving hemisphere 9, and the laser receiver 94 cannot receive the laser light, and then generates reflected light, and the reflected light falls on the light receiving plate 81 to generate an obvious laser light spot;

[0057] S4. At this time, the secondary high-definition camera obtains the image information and feeds the signal back to the control center. The control center controls the expansion ball 92 to rotate 90° toward the laser point on the light receiving plate 81 according to the image information, so that the laser falls on the light-changing arc plate 93. Then the control center controls the light-changing arc plate 93 to move back and forth horizontally, thereby continuously changing the reflection angle, so that the laser light spot on the light receiving plate 81 changes continuously, thereby reminding the on-site staff who are loading or unloading materials, so as to detect abnormalities in time and shut down and perform maintenance.

[0058] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.

5. The highly integrated automatic assembly equipment for automobile camera bracket according to claim 1, characterized in that: The method for using the workstation monitoring unit comprises the following steps: S1, each time the multi-station turntable (2) rotates 360°, the laser emitter (82) is controlled to automatically turn on, so that the laser emitter (82) emits a laser beam toward the differential light-receiving hemisphere (9) and irradiates the differential light-receiving hemisphere (9); S2, when the multi-station turntable (2) does not rotate and deviate, the laser beam is vertically directed toward the differential light-receiving hemisphere (9) and passes through the light hole (901) to fall on the laser receiver (94). At this time, the reflected light coincides with the laser beam, and no laser light spot is generated on the light-receiving plate (81); S3, when there is a cumulative tolerance, the multi-station turntable (2) rotates and deviates, and the coaxiality between the differential light-receiving hemisphere (9) and the laser emitter (82) is destroyed.

The control center controls the expansion ball (92) to rotate 90 degrees toward the side of the laser point on the light receiving plate (81) according to the image information, so that the laser falls on the light-changing arc plate (93). Then the control center controls the light-changing arc plate (93) to move back and forth horizontally, thereby continuously changing the reflection angle, so that the laser light spot on the light receiving plate (81) continuously changes, thereby alerting the on-site staff who are loading or unloading materials, so as to facilitate timely detection of abnormalities and shut down and maintenance.
