Description

Technical Field

[0001] The present invention relates to the technical field of infrared detector manufacturing, and specifically to an automatic assembly method and assembly line for infrared detectors. Background Art

[0002] An infrared detector assembly line is a production line designed based on the principles of automation and assembly line operation. Its basic principle is to decompose the assembly process of an infrared detector into a series of standardized processes, and connect these processes through automated equipment to form a continuous and efficient production process. The operation of the assembly line depends on various automated equipment such as sensors, controllers, and actuators, which can precisely control the conveying, positioning, and assembly processes of components, thereby achieving efficient and precise assembly operations. And the assembly method usually uses the automated equipment involved in the above process to achieve a complete assembly process. Through different assembly methods, the aim is to improve production efficiency, reduce labor costs, and ensure product quality.

[0003] During the assembly process, since the installation between the face cover and the bottom box is through the placement of a manipulator, when the placement position of the bottom box is fixed, the face cover will cover the bottom box from top to bottom at the same position, thus forming an assembly. However, when the bottom box is placed on the turntable, it will shake due to unstable bottom, which will cause eccentricity, affecting the calibration accuracy between the face cover and it, and further affecting the assembly efficiency and qualification rate of the infrared detector; in addition, the installation of the face cover and the bottom box requires a certain engagement. When the face cover and the bottom box are not calibrated, squeezing the face cover will cause hard interference at the connection between the face cover and the bottom box, which will cause damage to the face cover or the bottom box, further affecting the assembly efficiency and qualification rate of the infrared detector.

[0004] To solve the above problems, various solutions have been proposed in the prior art. For example, the bottom box is fixed at a specified position. However, during the automated assembly process, the assembled bottom box will be removed later and an unassembled bottom box will be placed. If the bottom box is fixedly installed, the assembly speed will be reduced, which will affect the assembly efficiency of the infrared detector.

[0005] Based on this, in order to solve the problem that it is difficult to calibrate the face cover and the bottom box due to their unfixed shapes during the automated assembly of infrared detectors, the present invention designs an automatic assembly method and assembly line for infrared detectors. Summary of the Invention

[0006] An automatic assembly method and assembly line for infrared detectors provided by the present invention solve the problem that during the automated assembly process of infrared detectors, because the bottom box needs to be disassembled and assembled conveniently, the bottom box will not be completely fixed, which makes it difficult to calibrate the face cover and the bottom box during assembly. By adaptively adjusting the fixing effect of the bottom box through the downward movement distance of the bottom box, and at the same time using the negative pressure adsorption method to achieve the calibration and fixing of the face cover and the bottom box, the assembly efficiency of the infrared detector is improved.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] The present invention provides an automatic assembly method for infrared detectors, comprising the following steps:

[0009] S1: The bottom box is picked up by the robot and placed in the carrier; then the conveying device cooperates with the robot to load the sponge into the specified position of the bottom box.

[0010] S2: The bottom box is fixed from the bottom by the suction cup, the robot takes the substrate and the cover, and puts the substrate into the bottom box, and puts the cover next to the bottom box. The robot pushes the substrate to the inside of the bottom box and fixes the bottom box by the fixing device.

[0011] S3: Fix the cover by pressing device, and then install the rubber screws on the cover by robot; identify the position of substrate by detection device, and send out defective products.

[0012] S4: The robot puts the cover on the bottom box and adjusts the position of the rubber screws, and tightens the rubber screws with an electric screwdriver; the robot then uses laser engraving and barcode scanning to verify the correctness, thus completing the assembly.

[0013] The invention discloses an automatic assembly line for infrared detectors, which is assembled by the above-mentioned assembly method, and comprises a working platform, a manipulator, a turntable, a conveying device, a carrier, a bottom box, a fixing device, a substrate, a face cover, and a pressing device, wherein the manipulator is installed above the working platform, the turntable is installed at the center of the working platform, the conveying device is installed at the edge of the working platform, the carrier is installed on the turntable and distributed along the circular array of the turntable, the bottom box and the fixing device are both installed in the carrier, the substrate is installed inside the bottom box, the face cover is located above the bottom box, the pressing device is located above the turntable, the carrier clamps the bottom box through the fixing device, the pressing device is in contact with the carrier and drives the bottom box to align with the face cover, the fixing device limits the end position of the face cover, and the fixing device and the pressing device cooperate with each other to position the bottom box on the one hand to avoid deflection and shaking during assembly, and on the other hand to fix the bottom box and the face cover to each other by negative pressure adsorption, thereby facilitating the subsequent fixation between the two.

[0015] Preferably, the pressing device includes an electric push rod, a card slot, a sliding groove, a limiting block, a compression spring, an extrusion cover, and an extrusion rod. The electric push rod is installed above the working platform and corresponds to the position of the substrate. The card slot is opened above the carrier.

The compression spring is installed between the inner wall of the card slot and the limiting block. The extrusion cover is installed at the output end of the electric push rod. The extrusion rod is installed on the side wall of the extrusion cover and corresponds to the card slot. On the one hand, it further fixes the bottom box. On the other hand, it will further push the push block towards the center through the wedge block, and then squeeze the suction cup, causing the suction cup to deform and form a negative pressure adsorption, thereby fixing the face cover and the bottom box.

[0016] Preferably, a support plate is installed in the placement groove, and a support spring is installed at the bottom of the support plate. Initially, the bottom box will squeeze the support plate until the bottom of the support plate is restricted by the limiting block, thereby forming the installation of the bottom box.

[0017] Preferably, an inclined groove is opened on the upper surface of the limiting block, and an inclined surface is provided below the extrusion rod. The inclined groove corresponds to the inclined surface. The inclined surface on the extrusion rod can push the limiting block outward through the inclined groove, thereby realizing the extrusion of the limiting block and forming a constraint at the same time.

[0018] Preferably, a fixing groove is opened in the center of the support plate, and the shape of the fixing groove is the same as that of the bottom of the bottom box, which is convenient for the positioning and stability of the bottom box, and thus convenient for the assembly of the bottom box and the face cover.

[0020] Preferably, the suction cup is made of rubber material. After being squeezed, the connection between the suction cup and the bottom box and the face cover fits. On the one hand, it improves the fixing effect of the face cover and the bottom box respectively. On the other hand, through the negative pressure adsorption, the face cover and the bottom box become an integral body, which is convenient for the subsequent fixing of the glue screws.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The present invention proposes an automatic assembly method for infrared detectors, which fixes the bottom box from the bottom by a suction cup, and a robot takes the substrate and the surface cover, and installs the substrate into the bottom box, and puts the surface cover next to the bottom box. The robot pushes the substrate to the inside of the bottom box, and another robot opens the bottom box lock, presses on the substrate, and fixes the bottom box by a fixing device; the conveying device automatically sends in the rubber screws, fixes the surface cover by a pressing device, and then uses the robot to install the rubber screws on the surface cover; the detection device identifies the position of the substrate, and sends out defective products, thereby improving the assembly efficiency of the infrared detector.

[0023] 2. The present invention proposes an automatic assembly line for infrared detectors, in which the clamping block limits and corrects the bottom box, driving it to be gradually placed along the contour of the carrier, thereby fixing the bottom box; the suction cup is driven to move toward the bottom box by the fixing device, and then the bottom box is clamped and fixed by the suction cup; subsequently, when the pressing device pushes the surface cover to move toward the bottom box, on the one hand, it will calibrate itself correspondingly with the carrier, so that the surface cover moves downward corresponding to the bottom box, and then under the action of the electric push rod, it can just fit on the bottom box, thereby forming an assembly, and when the electric push rod continues to press, it will continue to squeeze the bottom box downward through the surface cover, and at this time, when the bottom box is squeezed again, it will drive the suction cup to move closer to the middle, and then squeeze the surface cover and the bottom box, and at this time, the suction cup will be compressed, thereby forming a negative pressure to fix the surface cover and the bottom box, on the one hand, the surface cover and the bottom box can realize their own fixation and limiting of the carrier, and on the other hand, the surface cover and the bottom box are fixed to each other, thereby facilitating subsequent fixing with rubber screws.

[0024] 3. The present invention proposes an automatic assembly line for infrared detectors, which drives the face cover and the bottom box to be squeezed together by moving the electric push rod downward. In the process of the electric push rod moving downward, the squeezing cover will be driven downward to squeeze the face cover, and the squeezing rod on the squeezing cover will move into the card slot synchronously, thereby pushing the limit block in the slide slot to move to both sides and squeeze the compression spring. As the limit block moves, the support of the bottom box disappears and it will continue to move downward, while further pushing the clamping block until the reset spring reaches the limit state. At this time, the clamping block fixes and limits the bottom box. At this time, on the one hand, the bottom box is further fixed, and on the other hand, the wedge block will further push the push block to move toward the center, thereby squeezing the suction cup, causing the suction cup to deform, forming negative pressure adsorption, and thereby fixing the face cover and the bottom box.

Detailed implementation manners

[0038] In order to better understand the above solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0039] As Figure 1 shown, an automatic assembly method for an infrared detector provided by the present invention includes the following steps;

[0040] S1: The bottom box 6 is extracted by the robot 2 and placed in the carrier 5; then the conveying device 4 cooperates with the robot 2, the conveying device 4 automatically delivers the sponge, and the robot 2 takes the sponge and puts it into the specified position of the bottom box 6.

[0041] S2: fix the bottom box 6 from the bottom through the suction cup 77, the robot 2 takes the substrate 8 and the cover 9, installs the substrate 8 into the bottom box 6, puts the cover 9 next to the bottom box 6, the robot 2 pushes the substrate 8 to the inside of the bottom box 6, another robot 2 opens the lock of the bottom box 6, presses on the substrate 8, and fixes the bottom box 6 through the fixing device 7.

[0042] S3: The conveying device 4 automatically feeds in the rubber screws, fixes the cover 9 through the pressing device 10, and then installs the rubber screws on the cover 9 using the robot 2; the position of the substrate 8 is identified through the detection device, and defective products are sent out.

[0043] S4: The suction cup 77 fixes the bottom box 6 from the lower end, and the robot 2 covers the surface cover 9 on the bottom box 6 and corrects the position of the rubber screws, presses the surface cover 9 and the bottom box 6, and tightens the rubber screws with an electric screwdriver; then the robot 2 laser engraves and scans the barcode to verify the correctness to achieve complete assembly.

[0044] like Figures 2 - 5 As shown, an automatic assembly line for infrared detectors is assembled by the above-mentioned assembly method, including a working platform 1, a manipulator 2, a turntable 3, a conveying device 4, a carrier 5, a bottom box 6, a fixing device 7, a substrate 8, a surface cover 9, and a pressing device 10. The manipulator 2 is installed above the working platform 1, the turntable 3 is installed at the center of the working platform 1, the conveying device 4 is installed at the edge of the working platform 1, the carrier 5 is installed on the turntable 3 and distributed in a circular array along the turntable 3, the bottom box 6 and the fixing device 7 are both installed in the carrier 5, the substrate 8 is installed inside the bottom box 6, the surface cover 9 is located above the bottom box 6, the pressing device 10 is located above the turntable 3, the carrier 5 clamps the bottom box 6 through the fixing device 7, the pressing device 10 is in contact with the carrier 5 and drives the bottom box 6 to align with the surface cover 9, and the fixing device 7 limits the end position of the surface cover 9.

[0045] The above work platform 1 is only one area of the infrared detector automatic assembly line. Figure 1As shown in the figure, the manipulator 2 receives the command output by the electric control operation of the terminal, and then realizes various commands such as rising, falling, and clamping. The turntable 3 is driven by a motor and rotates intermittently, thereby realizing the automatic installation of the infrared detector. After the turntable 3 rotates a certain angle, the conveying device 4 transmits various components to be installed at this time. Subsequently, the manipulator 2 picks up the bottom box 6 and places it in the carrier 5. As the bottom box 6 gradually descends within the carrier 5, the bottom box 6 gradually presses the clamping block 73 in the fixing device 7, and the clamping block 73 limits and corrects the bottom box 6 under the action of the spring, driving it to be gradually placed along the contour of the carrier 5. Moreover, as the bottom box 6 descends, the compression amount of the return spring 72 is greater, that is, the extrusion force on the clamping block 73 is greater, thereby realizing the fixation of the bottom box 6;

[0046] At the same time, the clamping block 73 will also drive the suction cup 77 to move towards the bottom box 6 through the fixing device 7, and then clamp and fix the bottom box 6 through the suction cup 77 (at this time, the suction cup 77 is not compressed and only fixes the bottom box 6 through clamping). And at this time, the suction cup 77 is not compressed, so no negative pressure adsorption will be formed. When the pressing device 10 pushes the face cover 9 towards the bottom box 6, on the one hand, through its corresponding calibration with the carrier 5, the face cover 9 moves downward corresponding to the bottom box 6, and then can just be clamped on the bottom box 6 under the action of the electric push rod 101, thereby forming an assembly. And when the electric push rod 101 continues to press, it will continue to press the bottom box 6 downward through the face cover 9. When the bottom box 6 is pressed again at this time, it will drive the suction cup 77 to move closer to the middle, thereby squeezing the face cover 9 and the bottom box 6. At this time, the suction cup 77 will be compressed, thereby forming a negative pressure to fix the face cover 9 and the bottom box 6. On the one hand, it realizes the fixation and limitation of the face cover 9 and the bottom box 6 relative to the carrier 5, and on the other hand, it makes the face cover 9 and the bottom box 6 fix each other, thereby facilitating the subsequent fixing with glue screws.

[0047] Through the mutual cooperation of the fixing device 7 and the pressing device 10, on the one hand, the bottom box 6 is positioned to avoid skew and shaking during assembly, and on the other hand, the bottom box 6 and the face cover 9 are fixed to each other by negative pressure adsorption, thereby facilitating the subsequent fixing between the two.

[0048] As Figures 5 - 7 shown, the fixing device 7 includes a placement groove 71, a return spring 72, a clamping block 73, a limiting groove 74, a wedge block 75, a push block 76, and a suction cup 77. The placement groove 71 is opened above the carrier 5. The return spring 72 is installed in the placement groove 71. The clamping block 73 is installed at the other end of the return spring 72. The limiting groove 74 is opened above the clamping block 73. The wedge block 75 and the push block 76 are installed in the placement groove 71. One end of the wedge block 75 is in contact with the limiting groove 74. The push block 76 is in contact with the other end of the wedge block 75. The suction cup 77 is connected to the other end of the push block 76;

[0049] The placement groove 71 on the vehicle 5 is used to place the bottom box 6. During the placement process by the manipulator 2, the clamping block 73 will be gradually extruded outward. At this time, the clamping block 73 will gradually compress the return spring 72, and the limiting groove 74 on the clamping block 73 will synchronously drive the wedge-shaped block 75 to move upward. The upward movement of the wedge-shaped block 75 will push the push block 76 to move towards the center, and then drive the suction cup 77 through the push block 76 to clamp the bottom box 6.

[0050] The pressing device 10 includes an electric push rod 101, a card slot 102, a sliding groove 103, a limiting block 104, a compression spring 105, a pressing cover 106, and a pressing rod 107. The electric push rod 101 is installed above the working platform 1 and corresponds to the position of the substrate 8. The card slot 102 is opened above the vehicle 5. The sliding groove 103 is opened below the card slot 102 and penetrates through the vehicle 5 to the lower part of the bottom box 6. The limiting block 104 is installed below the bottom box 6. The compression spring 105 is installed between the inner wall of the card slot 102 and the limiting block 104. The pressing cover 106 is installed at the output end of the electric push rod 101. The pressing rod 107 is installed on the side wall of the pressing cover 106 and corresponds to the card slot 102.

[0051] By moving the electric push rod 101 downward, the face cover 9 is driven to be extruded against the bottom box 6. During the downward movement of the electric push rod 101, the pressing cover 106 will be driven to press the face cover 9 downward. The pressing rod 107 on the pressing cover 106 will synchronously move into the card slot 102, and then push the limiting block 104 in the sliding groove 103 to move to both sides and compress the compression spring 105. As the limiting block 104 moves, the support for the bottom box 6 disappears at this time, and it will continue to move downward, and at the same time further push the clamping block 73 until the return spring 72 reaches the limit state. At this time, the clamping block 73 fixes and limits the bottom box 6. On the one hand, the bottom box 6 is further fixed, and on the other hand, the wedge-shaped block 75 will further push the push block 76 to move towards the center, and then squeeze the suction cup 77, causing the suction cup 77 to deform and form a negative pressure adsorption, thereby fixing the face cover 9 and the bottom box 6.

[0052] As Figure 9 shown, a support plate 711 is installed in the placement groove 71, and a support spring 712 is installed at the bottom of the support plate 711; in the initial state, the bottom box 6 can be placed on the support plate 711, and the uncompressed limiting block 104 is located at the bottom of the support plate 711. Initially, the bottom box 6 will squeeze the support plate 711 until the bottom of the support plate 711 is restricted by the limiting block 104, thereby forming the installation of the bottom box 6. When the electric push rod 101 moves downward, it will drive the limiting block 104 to move, and then drive the limiting block 104 to release the restriction on the support plate 711. At this time, under the extrusion of the electric push rod 101, the support spring 712 can be compressed again, thereby realizing the assembly of the face cover 9 and the bottom box 6.

[0053] As Figure 8As shown, an inclined groove 1041 is formed on the upper surface of the limit block 104, and an inclined surface 1071 is provided below the extrusion rod 107. The inclined groove 1041 corresponds to the inclined surface 1071. The inclined surface 1071 on the extrusion rod 107 can push the limit block 104 outward through the inclined groove 1041, thereby realizing the extrusion of the limit block 104. At the same time, it can also form a constraint, so that the electric push rod 101 and the carrier 5 will not be deflected, improving the assembly efficiency.

[0054] As Figure 10 shown, a fixing groove 713 is formed at the center of the support plate 711. The shape of the fixing groove 713 is the same as that of the bottom of the bottom box 6. Based on the different shapes of the bottom box 6, different support plates 711 can be set. For example, if the bottom box 6 is arc-shaped, an arc-shaped fixing groove 713 can be formed on the support plate 711 at this time. The fixing groove 713 only needs to be able to support the bottom of the bottom box 6, so as to facilitate the positioning and stability of the bottom box 6, and further facilitate the assembly of the bottom box 6 and the face cover 9.

[0055] As Figure 11 shown, an activity groove 731 is formed on the surface of the clamping block 73. An activity block 732 is installed in the activity groove 731, and a rubber plate 733 is installed outside the activity block 732. As the electric push rod 101 moves downward, it will drive the face cover 9 and the bottom box 6 to move downward synchronously. At this time, the bottom box 6 is restricted by the slider. If the bottom box 6 moves downward again, friction will be formed between the bottom box 6 and the clamping block 73. Therefore, the activity block 732 and the rubber plate 733 are provided. The rubber plate 733 will move downward synchronously with the bottom box 6. It slides in the activity groove 731 through the activity block 732. Of course, a spring is provided at the bottom of the activity block 732 and the activity groove 731 for resetting.

[0056] The suction cup 77 is made of rubber. After being extruded, the suction cup 77 fits the connection between the bottom box 6 and the face cover 9. The suction cup 77 can fit the connection between the face cover 9 and the bottom box 6. On the one hand, it improves the fixing effect of the face cover 9 and the bottom box 6 respectively. On the other hand, through negative pressure adsorption, the face cover 9 and the bottom box 6 become an integral body, which is convenient for subsequent fixing with glue and screws.

[0057] When an infrared detector needs to be assembled, the turntable 3 rotates to move the unassembled bottom box 6 under the electric push rod 101. The manipulator 2 first grabs the bottom box 6 and places it on the carrier 5. At this time, the bottom box 6 will gradually squeeze the support plate 711, and at the same time, the bottom box 6 will also squeeze the clamping block 73. The clamping block 73 is squeezed by the bottom box 6 and will gradually squeeze the return spring 72. At the same time, it will also drive the wedge block 75 to move upward through the limiting groove 74. The wedge block 75 will squeeze the push block 76, thereby driving the suction cup 77 to clamp the bottom box 6. At this time, the manipulator 2 grabs the face cover 9 to the lower part of the extrusion cover 106 of the electric push rod 101 and drives the electric push rod 101. The electric push rod 101 drives the extrusion cover 106 to push the face cover 9. At this time, when the extrusion cover 106 moves towards the face cover 9, it will gradually push the limiting block 104 in the sliding groove 103 through the extrusion rod 107, thereby driving the limiting block 104 to release the restraint on the support plate 711. At this time, the electric push rod 101 will drive the face cover 9 to further squeeze the bottom box 6, thereby driving the bottom box 6 to push the support plate 711 downward. The support plate 711 passes over the limiting block 104, while the bottom box 6 still further squeezes the clamping block 73, thereby pushing the push block 76 through the wedge block 75. The push block 76 drives the suction cup 77 to further squeeze the bottom box 6 and the face cover 9, thereby forming a negative pressure adsorption at the junction of the bottom box 6 and the face cover 9, which is convenient for the subsequent installation of glue screws.

[0058] The above shows and describes the basic principles and beneficial effects of the present invention. At the same time, the present invention is not limited by the above embodiments. Without departing from the effects and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
