Description

Technical Field

[0001] This application belongs to the technical field of die bonding, and more specifically, relates to a straight fork die bonding device. Background Art

[0002] During the process of assembling LED chips on an LED bracket, a bracket supply device is required to output the brackets in the cassette to continuously supply brackets to the bracket transmission device. The bracket transmission device conveys the brackets to the die bonding position for die bonding operations. Using a cassette to store brackets, the gap between adjacent brackets in the cassette is relatively large, resulting in a low density of brackets stored in the cassette and the need to frequently replace the cassette. Since the width and length dimensions of the cassette are fixed, only brackets with matching length and width can be stored, and brackets of different models cannot be compatible. At the same time, due to the differences in the sizes of the jigs used for die bonding different brackets, the compatibility of the entire machine is poor. Summary of the Invention

[0055] Please refer to Figure 1 、 Figure 2 and Figure 5, the direct fork die bonding equipment provided by the embodiments of the present application will be described. The direct fork die bonding equipment includes a machine table 10, a loading device 20, a loading device 20, a transmission device 30, a positioning device 40, a dispensing device 50, a die bonding device 60, and a receiving device 70. The loading device 20 includes a first lifting mechanism 21 and a picking mechanism 22. The first lifting mechanism 21, the picking mechanism 22, the loading device 20, the transmission device 30, the positioning device 40, the dispensing device 50, the die bonding device 60, and the receiving device 70 are installed on the machine table 10. The first lifting mechanism 21 is used to drive the fork rack 80 to lift and lower. The picking mechanism 22 is used to pick up the bracket 90 on the fork rack 80 to input the bracket 90 into the transmission device 30. The transmission device 30 is used to convey the bracket 90 to control the bracket 90 to pass through the positioning device 40. The positioning device 40 is used to hold and position the positions of the pins on the bracket 90 to facilitate the precise positioning of the positions of each pair of pins in the bracket 90. The dispensing device 50 is used to dispense glue on the bracket 90. The die bonding device 60 is used to assemble the chip on the bracket 90. The receiving device 70 is used to store the bracket 90 on the fork rack 80. By using the first lifting mechanism 21 to drive the fork rack 80 to lift and lower, the height of the fork rack 80 can be matched with the height of the picking mechanism 22, so that the picking mechanism 22 can take out the bracket 90 stored on the fork rack 80, realizing the feeding of the bracket 90 through the fork rack 80, improving the storage density of the bracket 90 in the loading device 20, reducing the frequency of replacing the fork rack 80, and saving labor costs. By using the positioning device 40, the positions of the pins in the bracket 90 can be held and positioned, realizing the precise positioning of the pin positions, so as to keep the dispensing positions and die bonding positions corresponding to each pair of pins in the bracket 90 consistent and improve the consistency of the product. Since the pins in the bracket 90 can be kept corresponding to the dispensing positions and die bonding positions, the positions of each pair of pins in the brackets 90 with different lengths and widths can be held and positioned by the positioning device 40, thereby being compatible with the die bonding requirements of different models of brackets 90 and improving the compatibility of the whole machine.

[0056] In an embodiment of the present application, please refer to Figure 1 , Figure 2 and Figure 9 , the fork rack 80 includes a handle 81, a first support plate 82, a second support plate 83, and a fork arm 84. The fork arm 84 is used to fork the bracket 90. The first support plate 82 is connected to one end of the fork arm 84 away from the picking mechanism 22. The second support plate 83 supports the first support plate 82. The handle 81 is installed on the side of the first support plate 82 away from the fork arm 84. The second support plate 83 is detachably connected to the first lifting mechanism 21. By using the handle 81, it is convenient to hold and facilitate the replacement of the fork rack 80, so that after the brackets 90 in the fork rack 80 are taken out, the brackets 90 can be replaced for feeding.

[0057] Optionally, there are multiple groups of fork arms 84. A plurality of fork arms 84 in each group are arranged along the length direction of the first support plate 82. The multiple groups of fork arms 84 are arranged side by side along the width direction of the first support plate 82, and the multiple groups of fork arms 84 are arranged at intervals.

[0058] Optionally, the number of fork arms 84 in each group is two. In this way, the two ends of the length direction X of the bracket 90 can be respectively inserted to maintain the stability of the bracket 90. Among them, the length direction of the first support plate 82 is the same as the length direction X of the bracket 90, and the width direction of the first support plate 82 is the same as the width direction Z of the bracket 90.

[0059] In an embodiment of the present application, please refer to Figure 1 and Figure 2 , the first lifting mechanism 21 includes a lifting seat 211, a lifting drive assembly 212 and a fixed seat 213. The lifting drive assembly 212 is used to drive the lifting seat 211 to lift. The fixed seat 213 supports the lifting drive assembly 212. The fixed seat 213 is connected to the machine table 10, and the power output end of the lifting drive assembly 212 is connected to the lifting seat 211.

[0060] Optionally, the lifting seat 211 is used to support the fork rack 80. In this way, the lifting height position of the fork rack 80 can be adjusted. The lifting drive assembly 212 can be an existing linear drive assembly, which will not be elaborated here.

[0061] In one embodiment, a plurality of clamping seats 214 are installed on the lifting seat 211. Each clamping seat 214 is used to respectively clamp and position the fork rack 80. The plurality of clamping seats 214 are arranged side by side and at intervals along the height direction of the lifting seat 211. In this way, multiple layers of fork racks 80 can be loaded, and it is not necessary to stop the machine to replace the fork rack 80, realizing continuous feeding of the bracket 90. Among them, the height direction of the lifting seat 211 is the same as the width direction Z of the bracket 90.

[0062] Optionally, please refer to Figures 1 to 3 , a positioning groove for placing the bottom of the fork rack 80 is formed on the clamping seat 214. A clamping assembly 215 is installed on one side of the positioning groove of the clamping seat 214. The clamping assembly 215 is used to cooperate with the side wall of the positioning groove to clamp the fork rack 80. In this way, when the bottom of the fork rack 80 is placed in the positioning groove, the clamping assembly 215 can clamp the fork rack 80 to prevent it from moving during the feeding process of the fork rack 80, ensuring the stability of the horizontal position of the bracket 90. Specifically, the second support plate 83 is fitted into the positioning groove. The positioning groove has an opening on the side close to the material taking mechanism 22. The clamping assembly 215 is installed on the side of the clamping seat 214 close to the material taking mechanism 22. In this way, it is convenient to load the fork rack 80 from the side of the clamping seat 214 away from the material taking mechanism 22.

[0063] Optionally, the lifting seat 211 includes a first grid plate, a second grid plate, a first vertical plate, and a second vertical plate. The second vertical plate is slidably connected to the fixed seat 213. The power output end of the lifting drive assembly 212 is connected to the second vertical plate. The second vertical plate supports the first grid plate. The first vertical plate connects the side edges of the first grid plate and the second grid plate. A clamping seat 214 is installed on the first grid plate, and a clamping seat 214 is installed on the second grid plate. In this way, it is convenient to take out or load the fork rack 80 from the side of the lifting seat 211 away from the material taking mechanism 22, and the feeding of the double-layer fork rack 80 can be realized. Of course, in other embodiments of the present application, the number of the second grid plates can be multiple. In this way, multiple layers of fork racks 80 can be loaded simultaneously.

[0064] In an embodiment of the present application, please refer to Figures 1 to 3 , the clamping assembly 215 includes an abutting block, a sliding rod, a limiting seat, and a spring. The sliding rod is installed on the side of the abutting block away from the positioning groove. The limiting seat slidably supports the sliding rod. The spring is used to push the abutting block towards the positioning groove. The spring is sleeved on the sliding rod, and both ends of the spring are respectively abutted and connected to the abutting block and the limiting seat. When loading the fork rack 80 in this way, the abutting block automatically abuts against the second support plate 83 and automatically clamps the second support plate 83 in the positioning groove.

[0065] In an embodiment of the present application, please refer to Figures 1 to 3 , the material taking mechanism 22 includes a vacuum suction head 221, a first drive assembly 222, and a first base 223. The vacuum suction head 221 is used to suck the bracket 90 on the fork rack 80. The first drive assembly 222 is used to drive the vacuum suction head 221 to approach the first lifting mechanism 21. The first base 223 supports the first drive assembly 222. The first base 223 is installed on the machine table 10. The vacuum suction head 221 is connected to the power output end of the first drive assembly 222. In this way, it is possible to control the vacuum suction head 221 to take out the bracket 90 on the fork rack 80, so as to facilitate the feeding of the bracket 90.

[0066] In an embodiment of the present application, please refer to Figure 1 and Figure 2, the first driving assembly 222 includes a guide rail 2221, a slider 2222, a connecting block 2223, a driven wheel 2225, a driving wheel 2226, a belt 2224, and a second motor 2227. The slider 2222 is mounted on the first base 223. The guide rail 2221 is slidably connected to the slider 2222. One end of the guide rail 2221 is provided with the connecting block 2223, and the other end of the guide rail 2221 is connected to the vacuum chuck 221. The driven wheel 2225 and the driving wheel 2226 are cooperatively configured to support the belt 2224. The belt 2224 is connected to the connecting block 2223, and the belt 2224 is used to drive the connecting block 2223 to move. The second motor 2227 is mounted on the first base 223. The second motor 2227 is connected to the driving wheel 2226. The driven wheel 2225 is rotatably mounted on the first base 223. The second motor 2227 is used to drive the driving wheel 2226 to rotate. In this way, when the second motor 2227 drives the belt 2224 to move, the connecting block 2223 can be driven to translate, so that the guide rail 2221 drives the material taking mechanism 22 to approach or move away from the fork rack 80, so as to take the bracket 90 outside the fork rack 80 off the fork arm 84. Of course, in other embodiments of the present application, the first driving assembly 222 may also adopt other linear driving assemblies, such as a linear motor, etc.

[0067] In an embodiment of the present application, please refer to Figures 1 to 3 , the material taking mechanism 22 further includes a magnetic member 224 and a first driver 225. The first driver 225 is mounted on the vacuum chuck 221. The first driver 225 is used to drive the magnetic member 224 away from the first lifting mechanism 21. The magnetic member 224 is connected to the power output end of the first driver 225. The magnetic member 224 is used to cooperate with the vacuum chuck 221 to suck the bracket 90. In this way, the cooperation between the magnetic member 224 and the vacuum chuck 221 can enhance the stability of the bracket 90 during movement. When the material taking mechanism 22 approaches the bracket 90, the magnetic force of the magnetic member 224 can pull the bracket 90 closer to the vacuum chuck 221, so as to facilitate the vacuum chuck 221 to suck the bracket 90 and ensure the stability of the bracket 90. When the bracket 90 is released, the first driver 225 drives the magnetic member 224 away from the fork rack 80, so that the magnetic member 224 moves away from the bracket 90. At this time, the vacuum chuck 221 releases the vacuum, and the bracket 90 can be released, avoiding the magnetic force of the magnetic member 224 from interfering with the release of the bracket 90.

[0068] In an embodiment of the present application, please refer to Figure 3 , a slit 2211 for sucking the bracket 90 is formed on one side of the vacuum chuck 221 close to the first lifting mechanism 21. The slit 2211 is arranged along the length direction of the vacuum chuck 221. By cooperating the slit 2211 with the cross bar on the bracket 90, on the one hand, vacuum leakage can be avoided, and on the other hand, the adsorption area can be increased, improving the adsorption stability of the bracket 90.

[0069] In one embodiment of the present application, please refer to Figures 1 to 3 , the material taking mechanism 22 further includes a support rod 226 and a support plate 227. The magnetic attraction member 224 is installed at one end of the support rod 226 close to the first lifting mechanism 21. The support plate 227 is connected to the other end of the support rod 226. The support rod 226 is slidably inserted on the vacuum suction head 221. The support plate 227 is slidably connected to the vacuum suction head 221. The power output end of the first driver 225 is connected to the support plate 227. In this way, by the sliding connection between the support plate 227 and the vacuum suction head 221, the magnetic attraction member 224 can be controlled to move linearly, improving the stability of the movement of the magnetic attraction member 224. Optionally, the first driver 225 can be a cylinder or the like. In this way, it is convenient to control the magnetic attraction member 224 to move linearly.

[0070] Optionally, the number of the support rods 226 is multiple. The multiple support rods 226 are arranged along the length direction of the vacuum suction head 221. The magnetic attraction member 224 is installed at one end of each support rod 226 close to the fork rack 80. In this way, the magnetic force intensity can be improved and the magnetic force distribution can be made uniform. Among them, the length direction of the vacuum suction head 221 is the same as the length direction X of the bracket 90.

[0071] Optionally, a limiting rod is installed on the side of the vacuum suction head 221 away from the first lifting mechanism 21. The middle part of the limiting rod is slidably inserted on the support plate 227. In this way, the linear movement of the support plate 227 can be guided, the stability of the support plate 227 can be improved, and the separation of the support rod 226 from the vacuum suction head 221 can be restricted.

[0072] Optionally, the material taking mechanism 22 further includes a third tension spring 228. The third tension spring 228 connects the vacuum suction head 221 and the support plate 227 so that when the first driver 225 releases the thrust on the support plate 227, the third tension spring 228 can pull the support rod 226 to extend towards the fork rack 80. The number of the third tension springs 228 is two. The two third tension springs 228 are respectively located on both sides of the first driver 225. In this way, the stability of the movement of the support plate 227 can be improved.

[0073] In one embodiment of the present application, please refer to Figure 3 , the number of the magnetic attraction members 224 is two. The two magnetic attraction members 224 are respectively located at both ends of the length direction of the vacuum suction head 221. By using two magnetic attraction members 224, both ends of the bracket 90 can be adsorbed respectively, improving the stability of the bracket 90.
