Description

Technical Field

[0001] The present invention relates to electronic mounting equipment, in particular to a loading device and an automatic mounting machine with the loading device. Background Art

[0002] With the rapid development of science and technology, electronic products such as mobile phones, tablets, and car computers are constantly moving towards high-density integration and ultra-sophistication. The heat dissipation performance of electronic products is becoming increasingly important, and as a result, the requirements for the mounting equipment that connects the heat dissipation modules of electronic products to the circuit boards are becoming increasingly stringent. In the assembly process, flexible components such as long and short rubber strips and rubber blocks of a certain thickness are mounted at different locations on the heat dissipation module to protect the circuit boards. Due to the irregular shape and curvature of the heat dissipation module, the bonding is difficult. Furthermore, the irregular shape and elasticity of the rubber strips make bonding even more difficult. Furthermore, the assembly errors between the two rubber strips and the heat dissipation module, as well as the assembly errors between the two rubber strips themselves, must be strictly controlled within the required numerical range. At present, the alignment and bonding of the above-mentioned adhesive strips and adhesive blocks to the heat dissipation module is mostly done manually. The adhesive strips are directly peeled off from the material tape one by one, and then bonded to the heat dissipation module through the adhesive backing on the bottom. Since the adhesive backing has relatively strong adhesion and is not easy to peel off, it is necessary to press it to make it firmly bonded. Manual operation is inefficient, and the mounting accuracy and firmness cannot be effectively guaranteed.

[0013] In order to achieve the above-mentioned objectives, the present invention discloses an automatic placement machine, which includes a frame, a conveying device and a loading device arranged side by side on the frame at a certain interval, a heating device arranged below the conveying device, and a visual recognition device arranged at the conveying device and the loading device.

[0029] To describe in detail the technical content, structural features, achieved objectives and effects of the present invention, the following will be described in detail in conjunction with the embodiments and with reference to the drawings.

[0030] Please refer to Figures 1 to 12 , the present invention discloses an automatic mounter 100 for mounting a flexible part 300 on a workpiece 200 (see Figure 9 ) through an adhesive 301 provided at the bottom thereof (see Figure 2 ) to achieve initial fitting. In the present application, the workpiece 200 is specifically a heat dissipation module for heat dissipation protection of a circuit board in a vehicle-mounted computer, and its overall shape is roughly bat-shaped, including a heat dissipation part 202 having two wings and a positioning part 201 located at the relative center of the heat dissipation part 202. Heat dissipation fins are provided at both wings. Specifically, the two wings of the heat dissipation part 202 are symmetrically arranged and have a certain curvature. The heat dissipation part 202 is roughly in the shape of a "ji" character, and the positioning part 201 is rectangular. The flexible part 300 is specifically at least one of a rubber strip and a rubber block. Among them, the adhesive 301 is specifically a thermosensitive adhesive, and the bonding effect is better. The flexible parts 300 bonded to the edges of the two long sides and the two short sides of the positioning part 201 are strip-shaped rubber strips with unequal lengths, and the top surface of the strip-shaped rubber strips has an irregular shape and a certain curvature. The four rubber strips, two long and two short, can form a shaping frame for protecting the CPU in the circumferential direction of the positioning part 201. The flexible part 300 used for bonding to the relative positions of the two wings of the heat dissipation part 202 is a rubber block with a certain thickness. This machine can achieve automatic fitting of flexible parts in the form of rubber strips and rubber blocks, and has strong versatility.

[0031] Please refer to Figures 1 to 3The automatic placement machine 100 disclosed in the preferred embodiment of the present invention includes a frame 101, a conveying device 400 and a loading device 500 arranged side by side at a certain distance on the frame 101, a heating device 600 arranged below the conveying device 400, and a visual recognition device 700 arranged at the conveying device 400 and the loading device 500. The conveying device 400 is used to convey the workpiece 200 loaded on the positioning fixture 401. The heating device 600 can move linearly up and down relative to the conveying device 400, and is used to move the workpiece 200 from the bottom to the positioning fixture 401. 01 are in contact with each other to heat the workpiece 200 in the positioning fixture 401, the loading device 500 is used to peel off the flexible parts 300 arranged at equal intervals on the material belt 800 one by one, and transfer the flexible parts 300 with the back adhesive 301 exposed after peeling to fit with the heated workpiece 200, and the visual recognition device 700 is used to identify and locate the peeled flexible parts 300 and the workpiece 200 to be mounted, so as to achieve accurate positioning and mounting by adjusting the position of the flexible parts 300.

[0032] It should be noted that the automatic placement machine 100 of the present invention also includes a control system, which is electrically connected to the conveying device 400, the loading device 500, the heating device 600 and the visual recognition device 700, and is used to control the coordinated actions between the various devices. Among them, the control system is an existing design, and its structure and control principle are well known in the art, so it will not be described in detail here. In addition, in a preferred embodiment of the present invention, the automatic placement machine 100 of the present invention also includes a jig reflow device 900, which is arranged parallel to and spaced apart from the conveying device 400 below the frame 101, and is used for the recycling of the positioning jig 401. Accordingly, a lifting platform can be set at the front and rear ends of the conveying device 400 to position the jig 401 for recycling in the machine, or the jig reflow device 900 can be connected to other equipment in the production line to achieve the recycling of the positioning jig 401 in the entire production line.

[0033] See also Figure 3Specifically, in this embodiment, the conveyor device 400 further includes a mounting frame 402, two conveyor belts 403 arranged parallel and spaced apart on two side plates 4021 of the mounting frame 402, and a rotary motor 404 connected to the two conveyor belts 403. The rotary motor 404 is used to drive the two conveyor belts 403 to rotate synchronously, thereby transporting the positioning jig 401 supported on the two conveyor belts. The conveyor belt 403 is specifically an annular belt body, rotatably connected to the side plates 4021 via a driving pulley and a driven pulley. The output end of the rotary motor 404 is connected to the driving pulley via a synchronous belt, thereby driving the driving pulley to rotate, thereby driving the conveyor belt 403 to rotate on the driving pulley and the driven pulley. Specifically, in order to achieve more accurate positioning, the conveying device 400 also includes a lifting member 405 arranged between the two side plates 4021 and located below the conveyor belt 403. The lifting member 405 is driven by the lifting mechanism 406 connected to it. It can move up and down linearly relative to the conveyor belt 403, thereby blocking the positioning jig 401 conveyed on the conveyor belt 403 at the front side of the positioning jig 401, causing the conveyor belt 403 to stop conveying the positioning jig 401, so that the heating device 600 moves up close to the positioning jig 401 to heat the workpiece 200.

[0034] Continue reading Figure 3 , specifically, in this embodiment, the heating device 600 is located at the output end of the conveying device 400, the heating device 600 includes a heating plate 601 and a heating drive mechanism 602 connected to the heating plate 601, the heating plate 601 is also connected to the heating element 603, and the upper side end of the heating plate 601 is provided with a positioning protrusion 6011, the positioning protrusion 6011 corresponds to the through-hole provided on the positioning fixture 401, and the heating drive mechanism 602 can drive the heating plate 601 to move linearly up and down, so that the heating plate 601 can move up to the through-hole through which the positioning protrusion 601 passes through the positioning fixture 401, so as to abut against the bottom surface of the workpiece 200 in the positioning fixture 401, thereby continuously heating the workpiece 200 through heat conduction from the heating plate 601 to the heating element 603, so that the adhesive 301 of the flexible member 300 is adhered to the workpiece 200 with a certain temperature after heating, effectively improving the subsequent bonding efficiency. The distribution of the positioning protrusions 6011 corresponds to the bonding positions of the flexible member 300 to be bonded to the workpiece 200 .

[0035] See also Figure 1 、 Figure 2 and Figures 4 to 6Specifically, in the preferred embodiment of the present application, the loading device 500 disclosed in the present invention includes a discharge tray 10, a receiving tray 20, a stripping table 30, a receiving table 40, a stripping clamp 51 and a vacuum suction cup 61 installed on the frame 101. The discharge tray 10 and the receiving tray 20 are arranged on the mounting frame 1011 of the frame 101 with a vertical spacing, and are arranged one after the other along the conveying direction of the conveying device 400. The stripping table 30 is horizontally arranged on the mounting frame 1011 between the discharge tray 10 and the receiving tray 20. Between the material trays 20, the material receiving table 40 is arranged opposite to the stripping table 30 on the mounting frame 1011, the stripping clamp 51 is movably mounted above the stripping table 30 and the material receiving table 40, the vacuum suction cup 61 is movably and rotatably mounted above the material receiving table 40, and multiple flexible parts 300 are equidistantly pasted on the material strip 800, the material strip 800 carrying the flexible parts 300 is rolled into a roll and loaded on the material discharge tray 10, and the starting end of the material strip 800 is wrapped around the stripping table 30 and then connected to the material receiving tray 20. The rotation of the receiving tray 20 can drive the discharging tray 10 to rotate, so that the flexible parts 300 on the pulled material belt 800 can pass through the stripping table 30 in turn. The stripping clamp 51 can move linearly up and down and forward and backward relative to the stripping table 30, and use a relatively large clamping force to clamp the flexible parts 300 on the stripping table 30 one by one to the receiving table 40. The receiving table 40 has an anti-stick ceramic table 41 for receiving the flexible parts 300, and the vacuum suction cup 61 is used to transfer and load the flexible parts 300 on the anti-stick ceramic table 41, so as to align the flexible parts 300 and fit them on the workpiece 200 being heated.

[0036] The gap between the stripping table 30 and the anti-stick ceramic surface 41 is relatively small, effectively preventing the flexible component 300 from sliding through the gap without being peeled off. The sides of the stripping table 30 that face the anti-stick ceramic surface 41 have a certain curvature or taper, facilitating the stripping of the flexible component 300 from the strip 800. Furthermore, the heating device 600 and the receiving table 40 of the loading device 500 are arranged in a straight line, that is, the output end of the conveyor 400 is arranged in a straight line with the receiving table 40. This effectively shortens the travel distance of the vacuum chuck 61 and improves transfer and placement efficiency.

[0037] See also Figures 5 to 7 Specifically, in a preferred embodiment of the present application, the loading device 500 of the present invention further includes a heating element 70. Both the stripping table 30 and the anti-stick ceramic table 41 are provided with a heating element 70. Thus, through heat conduction from the corresponding heating element 70, the adhesive 301 of the flexible member 300 passing through the material receiving table 70 and placed on the anti-stick ceramic table 41 is heated, effectively improving the subsequent bonding efficiency. Specifically, the heating element 70 is a heating tube connected to an external heating device. Specifically, in order to monitor the temperature of the stripping table 30 and the anti-stick ceramic table 41, each is further connected to a temperature sensor 71 connected to a control system.

[0038] Combine Figure 6 and Figure 7 Specifically, in a preferred embodiment of the present application, the anti-stick ceramic table 41 is provided with at least one groove 411. The groove 411 is formed by the top surface of the anti-stick ceramic table 41 being recessed in the direction of its bottom surface. At least a portion of the flexible member 300 is located at the notch of the groove 411, thereby facilitating the visual recognition device 700 to capture the outer contour of the flexible member 300, effectively improving the efficiency and accuracy of recognition and positioning, and further enhancing placement accuracy. It should be noted that the provision of the groove 411 can also effectively reduce the contact area with the adhesive backing 301 of the flexible member 300, facilitating the subsequent removal of the vacuum suction cup 61, and can also reduce the material used for the anti-stick ceramic table 41, effectively reducing manufacturing costs. Specifically, multiple grooves 411 are arranged in parallel and spaced apart on the anti-stick ceramic table 41, and each is arranged along the horizontal width direction of the anti-stick ceramic table 41. The flexible part 300 is placed along the longitudinal direction of the anti-stick ceramic table 41, thereby spanning the ports of multiple grooves 411, thereby forming multiple data collection areas, effectively improving the accuracy of identification and positioning.

[0039] Specifically, in a preferred embodiment of the present application, in order to further improve the adaptability of the loading device 500 , the height difference between the anti-stick ceramic table 41 and the stripping table 30 is adjustable, thereby adapting to the transmission of flexible parts 300 of different thicknesses on the material belt 800 . Specifically, the stripping table 40 further includes a height adjustment assembly 42 connected to the anti-stick ceramic table 41. The height adjustment assembly 42 includes a fixed base 421, a connecting member 422, and a guide block 423. The fixed base 421 is fixedly connected to the mounting frame 1011 and is specifically located on the opposite rear side of the mounting frame 1011. The guide block 423 is vertically mounted on the opposite rear side of the mounting frame 1011 and is arranged in contact with or spaced apart from the fixed base 421. The connecting member 422 is slidably mounted on the fixed guide block 423, and the lower end of the connecting member 422 is liftably engaged with the fixed base 421. The upper end of the connecting member 422 is connected to the side end of the anti-stick ceramic table 41, thereby ensuring that the anti-stick ceramic table 41 is horizontally arranged on the front side of the mounting frame 1011. In actual use, the height difference between the anti-stick ceramic table 41 and the stripping table 30 can be adjusted by moving the connecting member 422 up and down to adjust its relative position with the fixed base 421 as needed.

[0040] See also Figure 4 、 Figure 5 、 Figure 6 and Figure 8Specifically, in a preferred embodiment of the present application, the loading device 500 of the present invention further includes a pulling mechanism 80 mounted on a mounting frame 1011 of the frame 101. The pulling mechanism 80 is used for the synchronous action of the rotation of the receiving tray 20 for receiving the material and the rotation of the discharging tray 10 for discharging the material. The pulling mechanism 80 includes a driving wheel 81, a driven wheel 82, and a driving motor 83. Positioning holes 801 are equidistantly provided at the edges of both sides of the material belt 800. Positioning protrusions 811 for engaging with the positioning holes 801 of the material belt 800 are evenly distributed on the circumference of both side ends of the driving wheel 81. The driving wheel 81 and the driven wheel 82 are arranged side by side, and a through-gap is formed between the two for the feeding belt 800 to pass through. The driving wheel 81 and the rotating shaft 21 of the receiving tray 20 are connected at the back of the mounting frame 1011 by a synchronous belt 84. The output end of the driving motor 83 and the driving wheel 81 are connected at the back of the mounting frame 1011 by a synchronous belt 85. Figure 8 As shown, the synchronous belt 84 and the synchronous belt 85 are respectively mounted on the driving wheel 81 at the positions indicated by w1 and w2. The driving motor 83 can drive the driving wheel 81 to rotate, causing the driven wheel 82 and the receiving tray 20 to rotate accordingly, thereby pulling the material belt 800, causing it to drive the discharge tray 10 to rotate and discharge the material. The flexible parts 300 on the material belt 800 are sequentially wound around the stripping table 30, and the material belt 300 stripped of the flexible parts 300 is wound on the receiving tray 20. Among them, the shape and size of the positioning protrusions 811 on the driving wheel 81 match the shape and size of the positioning holes 801 on the material belt 800, and the spacing between the positioning protrusions 811 corresponds to the spacing between the positioning holes 801. Therefore, the present application can effectively achieve precise positioning of the material belt 800 through the socketing of the positioning holes 801 of the material belt 800 with the positioning protrusions 811 of the driving wheel 81, further improving the loading accuracy.

[0041] See also Figure 6Specifically, to improve the adaptability of the loading device 500 of the present invention, the spacing between the driving wheel 81 and the driven wheel 82 is adjustable, specifically by means of an adjustment assembly 86 mounted on the mounting frame 1011. The fixed plate 861 of the adjustment assembly 86 is mounted on the mounting frame 1011, and the movable plate 862 of the adjustment assembly 86 is slidably mounted on the mounting frame 1011. One end of the movable plate 862 is connected to the fixed plate 861 with an adjustable spacing, and the other end of the movable plate 862 is connected to the driven wheel 82. By adjusting the spacing between the movable plate 862 and the fixed plate 861, the spacing between the driving wheel 81 and the driven wheel 82 can be adjusted, thereby adapting to the pulling and conveying of material strips 800 of different thicknesses. In addition, the driven wheel 82 can also make a small telescopic movement towards or away from the driving wheel 81 through the spring 863 provided between the movable plate 862 and the fixed plate 861, so that when the driving wheel 81 rotates to pull the material belt 800, the driven wheel 82 is relatively away from the driving wheel 81 and compresses the spring 863, allowing the material belt 800 to pass through. When the driving wheel 83 stops rotating, under the action of the restoring force of the spring 863, the driven wheel 82 resets to approach the driving wheel 81, thereby clamping the material belt 800 so that the stripping clamp 51 can clamp the flexible part 300 on the material belt 800.

[0042] Combine Figures 4 to 6 Specifically, in a preferred embodiment of the present application, the loading device 500 of the present invention further includes a shaping mechanism 90 mounted on a mounting frame 1011 of the frame 101. The shaping mechanism 90 is arranged between the discharge tray 10 and the stripping table 30, and is used to roll and shape the wound material strip 800. The shaping mechanism 90 includes a first pressure wheel 91, which is rotatably in contact with the front side end of the stripping table 30 and can float up and down relative to the stripping table 30, and is used to roll and shape the edge of the material strip 800 wound around the stripping table 30. Among them, the two side ends of the first pressure wheel 91 are provided with annular bosses 911 for pressing against the edges of the two side edges of the material strip 800. By rolling and shaping the edges of the two side edges of the material strip 800, the material strip 800 is transported more smoothly, effectively improving the clamping efficiency of the stripping clamp 51. Specifically, the first pressure wheel 91 can be rotatably mounted on the suspension frame 92 and can slide on the linear guide rail 921 arranged on the suspension frame 92. Specifically, it is pressed against the material strip 800 by its own weight, and rolls on the material strip 800 as the material strip 800 moves to achieve the purpose of shaping. When the stripping clamp 51 performs the stripping operation, the material strip 800 can also be limited to prevent it from moving, thereby improving the clamping efficiency.

[0043] Specifically, in a preferred embodiment of the present application, the shaping mechanism 90 further includes a second pressing wheel 93 and a guide wheel 94 rotatably mounted on a mounting frame 1011 of the frame 101. The guide wheel 94 is arranged flush with the stripping table 30 on the side of the discharge tray 10. The second pressing wheel 93 can be floated above the guide wheel 94, and a gap is formed between the second pressing wheel 93 and the guide wheel 94 for the feed belt 800 to pass through. The second pressing wheel 93 is used to roll and shape the top side end of the flexible member 300 or / and the edge of the material belt 800 on the material belt 800 before it passes through the stripping table 30. When the second pressing wheel 93 rolls and shapes the top side end of the flexible member 300 and the edge of the material belt 800 at the same time, the height difference between the center of the second pressing wheel 93 and the edge of its two side ends is relatively small. When the second pressing wheel 93 only rolls and shapes the edge of the material belt 800, its structure is similar to that of the first pressing wheel 91. At this time, the height difference between the center of the second pressing wheel 93 and the edge of its two side ends is relatively large. When the present invention simultaneously incorporates a first pressure wheel 91, a second pressure wheel 93, and a guide wheel 94, the secondary rolling and shaping process achieves even better conveying results. More specifically, the shaping mechanism 90 further comprises a fixed plate 95, a sliding plate 96 slidably mounted on the fixed plate 95, and a spring 97 connected between the fixed plate 95 and the sliding plate 96. The second pressure wheel 93 is rotatably mounted on the sliding plate 96. As the strip 800 moves, the second pressure wheel 93 rolls on the strip 800 to achieve the desired shaping. Furthermore, the strip 800 is restrained by the stripping jaws 51 during stripping operations, preventing it from moving and thus improving gripping efficiency.

[0044] See also Figure 9 Specifically, in a preferred embodiment of the present application, the loading device 500 of the present invention further includes a clamping jaw transfer mechanism 50, the output end of which is connected to the stripping jaw 51, and is used to drive the stripping jaw 51 to move linearly up and down and forward and backward relative to the stripping table 30. The clamping jaw transfer mechanism 50 includes a transverse drive 52, a vertical drive 53 slidably mounted on the output end of the transverse drive 52, a first adapter plate 54 connected to the output end of the vertical drive 53, a second adapter plate 55 slidably mounted on the first adapter plate 54, and a clamping drive 56 mounted on the second adapter plate 55. The stripping jaw 51 is connected to the output end of the clamping drive 56. The transverse drive 52 and the vertical drive 53 are used to drive the stripping jaw 51 to move linearly forward and backward and up and down, respectively. In order to prevent the stripping jaw 51 from moving too fast, a spring 57 is connected between the first adapter plate 54 and the second adapter plate 55. The transverse drive 52 and the vertical drive 53 may be linear motors, and the clamping drive 56 may be a cylinder.

[0045] See also Figure 10 and Figure 11The loading device 500 of the present invention also includes a suction cup transfer mechanism 60. The suction cup transfer mechanism 60 includes a four-axis robot 62, a connecting plate 63 connected to the output end of the four-axis robot 62, and a sliding plate 64 slidably mounted on the connecting plate 63. A vacuum suction cup 61 is detachably connected to the sliding plate 64, and the vacuum suction cup 61 has a suction surface corresponding to the outer shape of the flexible member 300. The four-axis robot 62 drives the vacuum suction cup 61 to perform linear and rotational motion to absorb and transfer the flexible member 300, pressing it onto the workpiece 200. A spring 65 is provided between the connecting plate 63 and the sliding plate 64 to convert the rigid motion of the vacuum suction cup 61 into flexible motion, thereby preventing damage to the workpiece 200 caused by excessive movement or excessive pressure during the suction and bonding process. Furthermore, a micro pressure sensor 66 is provided between the output end of the four-axis robot 62 and the connecting plate 63 to monitor the pressure applied by the vacuum suction cup 61 to the workpiece 200 during the suction and bonding process, further protecting the workpiece 200.

[0046] Specifically, in a preferred embodiment of the present application, when the flexible part 300 has a certain thickness, a clamping plate 67 is further provided on the side of the vacuum suction cup 61. The clamping plate 67 is connected to the output end of the linear driver 68 installed on the sliding plate 64. Driven by the linear driver 68, it can make a linear motion close to or away from the vacuum suction cup 61 to support the flexible part 300 located in the vacuum suction cup 61 from the side, thereby cooperating with the vacuum suction cup 61 to effectively prevent the flexible part 300 from falling during the transfer process.

[0047] Combine Figure 1 、 Figure 2 and Figure 12 The visual recognition device 700 includes a first top camera 701, a second top camera 702, and a bottom camera 703. The first top camera 701 is fixed above the receiving platform 40 and is used to identify and locate the position coordinates of the flexible part 200 on the receiving platform 40 so that the vacuum suction cup 61 can pick up the material. The second top camera 702 is movably mounted above the output end of the conveyor 400, specifically at a position opposite the heating device 600, and is used to identify and locate the coordinates of the placement position of the workpiece 200. The bottom camera 703 is located between the receiving platform 40 and the conveyor 400 and is used to identify and locate the position coordinates of the flexible part 300 transferred by the vacuum suction cup 50 from the bottom. The second top camera 702 and the bottom camera 703 identify and locate the flexible part 300, thereby adjusting the placement position and angle of the flexible part 300 to ensure more accurate bonding between the flexible part 300 and the workpiece 200. The bottom camera 703 is provided with a beam sensor 704 for sensing the flexible part 300.

[0048] The following combination Figures 1 to 12The working principle of the loading device 500 of the present invention and the automatic placement machine 100 having the loading device 500 is described as follows:

[0049] After the equipment is started, under the instruction of the control system, the heating element 70 is activated to conduct heat to the stripping table 30 and the receiving table 40 respectively, and the heating element 603 conducts heat to the heating plate 601; then, when the positioning fixture 401 carrying the workpiece 200 is placed in or flows into the machine, the sensor located at the input end of the conveying device 400 sends a signal to the control system. Under the instruction of the control system, the conveying device 400 is activated to convey the positioning fixture 401 to the heating device 600; when the sensor located at the heating device 600 sends a signal to the control system, Under the instruction of the control system, the lifting member 405 is driven by the lifting mechanism 406 to move linearly upward to block the positioning fixture 401. The conveying device 400 stops conveying the positioning fixture 401, and the heating device 600 moves upward to abut against the bottom surface of the workpiece 200 in the positioning fixture 401 to heat the workpiece 200. The second top camera 702 located above the workstation can move linearly relative to the positioning fixture 401, thereby identifying the coordinates of the placement positions of the multiple workpieces 200 carried thereon one by one and sending the information to the control system.

[0050] At the same time, under the instruction of the control system, the driving motor 83 of the loading device 500 drives the active wheel 81 to rotate, so that the driven wheel 82 and the receiving tray 20 rotate accordingly, thereby pulling the material belt 800, and the discharge tray 10 rotates accordingly to discharge the material, and the flexible parts 300 on the material belt 800 are wound around the stripping table 30 in turn; then the clamping claw transfer mechanism 50 drives the stripping claw 51 to move up and down and forward and backward relative to the stripping table 30, so as to clamp the flexible parts 300 from the material 800 one by one to the anti-stick ceramic table 41 of the receiving table 40, and the material belt 800 with the flexible parts 300 peeled off is wound onto the receiving tray 20; the first top camera 701 located above the anti-stick ceramic table 41 recognizes the position coordinates of the flexible part 200 on the receiving table 40 The vacuum suction cup 61 is positioned separately and the information is sent to the control system; under the instruction of the control system, the suction cup transfer mechanism 60 drives the vacuum suction cup 61 to perform linear motion and rotational motion, thereby sucking and transferring the flexible part 300 to press it onto the workpiece 200; and in the process of the vacuum suction cup 61 transferring the flexible part 300, the bottom camera 703 identifies and locates the position coordinates of the flexible part 300 from the bottom, and sends the information to the control system. The control system compares the identification information of the workpiece 200 and the flexible part 300 fed back by the second top camera 702 and the bottom camera 703, and issues a command to make the vacuum suction cup 61 adjust the mounting position and angle of the flexible part 300, thereby achieving accurate alignment and fitting between the flexible part 300 and the workpiece 200;

[0051] Finally, after the bonding is completed, according to the instructions of the control system, each device is reset accordingly, and the conveying device 400 transfers the bonded workpiece 200 out of the machine for discharge;

[0052] By repeating the above operations continuously, the automated production line operation of peeling and loading the flexible component 300 on the material strip 800 and mounting the flexible component 300 on the workpiece 200 can be achieved.

[0053] Compared with the prior art, in the loading device 500 of the present invention, under the action of the pulling force of the rotating material discharge disk 10 driven by the rotating material collection of the material receiving disk 20, the flexible parts 300 equidistantly arranged on the material belt 800 are sequentially wound around the stripping table 30, and the stripping claws 51 are combined with the linear reciprocating motion between the stripping table 30 and the receiving table 40, so that the flexible parts 300 on the stripping table 30 are peeled off one by one by the stripping claws 51 with a relatively large clamping force, and clamped to the anti-stick ceramic table 41 of the receiving table 40. Since the surface of the anti-stick ceramic table 41 is relatively rough, the anti-stick performance is good and the heating effect is good, the flexible parts 300 deformed due to clamping are quickly restored by a short stay on the anti-stick ceramic table 41, and will not adhere to the anti-stick ceramic table 41, thereby The vacuum suction cup 61 accurately and efficiently transfers the flexible part 300 for press-fitting and mounting. The entire loading device 500 has a simple and compact structure, high transmission accuracy and high efficiency, thereby effectively improving the mounting efficiency and effect of the machine; in addition, the heating device 600 of the automatic mounting machine 100 of the present invention can move linearly up and down relative to the conveying device 400 to heat the workpiece 200 in the positioning fixture 401, so that the loading device 500 transfers the flexible part 300 to fit with the heated workpiece 200, heating and fitting at the same time, further improving the fitting efficiency and making the fitting more firm, and the visual recognition device 700 also identifies and locates the mounting positions of the flexible part 300 and the workpiece 200 respectively, thereby facilitating position adjustment during mounting and further improving mounting accuracy.

[0054] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope of the present invention.
