The vertical plates 72 are provided with a plurality of pallets 73 arranged at equal intervals along the vertical direction, and the pallets 73 are between the two vertical plates 72. The pallets 73 on the two vertical plates 72 constitute a plurality of pallet groups, and each pallet group includes two pallets 73 with the same height position, and the two pallets of the same group are respectively arranged on different vertical plates 73. The distance between the two pallets of the pallet group is less than the width of the packaging rack 70, and the packaging rack 70 is used to place workpieces. Each pallet group is used to place a packaging rack 70, and multiple packaging racks 70 can be placed on the lifting platform, Figure 1 Except for the topmost pallet group, which does not have a sub-assembly rack 70, each of the other pallet groups has a sub-assembly rack 70. Figure 2 The rear ends of the two pallets 73 of the pallet group are connected together by a connecting plate 78. The middle part of the connecting plate 78 is provided with a convex strip 79 extending upward. The convex strip 79 is used for positioning and limiting when the sub-assembly rack 70 is placed on the pallet group. In this embodiment, the two pallets 73 of the pallet group, the connecting plate 78 and the convex strip 79 are integrally formed.

[0013] The outer wall surface of the vertical plate 72 is provided with a vertical guide rail 74, and the workbench 1 is provided with a groove that cooperates with the guide rail 74. The lifting platform can move up and down relative to the workbench 1 along the direction of the guide rail 74. The lifting platform also includes a mounting plate 75 fixedly arranged below the bottom plate 71. The lifting drive mechanism is used to drive the lifting platform to move up and down, including a motor 76, a belt transmission mechanism, a screw rod 77 and a nut that cooperates with the screw rod 77. The motor 76, the belt transmission mechanism and the nut are arranged on the mounting plate 75. The output shaft of the motor 76 is connected to the driving wheel of the belt transmission mechanism. The nut is coaxially installed on the passive wheel of the belt transmission mechanism. The two ends of the screw rod 77 are installed on the workbench 1 and cooperate with the nut. Start the motor 76, and drive the nut to rotate through the belt transmission mechanism. The rotation of the nut on the screw rod 77 causes the change of its position on the screw rod 77, and the lifting platform moves up and down with the nut.

[0014] See also Figure 1 , Figure 3 and Figure 4 The transport mechanism is arranged on the workbench 1, located on one side of the lifting platform, and includes a lifting plate 81, a transport plate 82, a lifting drive 83 and a transport drive. The lifting plate 81 is arranged on the workbench 1 so as to be movable up and down, and is driven by the lifting drive 83. The transport plate 82 is arranged on the lifting plate 81, and can move forward and backward relative to the lifting plate 81, and is driven by the transport drive. A horizontal guide rail 84 is arranged on the lifting plate 81, and a slider matching the horizontal guide rail 84 is arranged on the transport plate 82. Under the drive of the transport drive, the transport plate 82 can move back and forth along the horizontal guide rail 84. The width of the transport plate 82 is smaller than the distance between the two pallets 73 of the pallet group. When the lifting platform moves downward to a suitable position, the transport driving member drives the transport plate 82 to move forward and insert it into the position between the two vertical plates 72. Then the lifting driving member 83 drives the lifting plate 81 to move upward. The transport plate 82 moves upward together with the lifting plate 81 to lift up the sub-assembly rack 70 above the transport plate 82 and closest to the transport plate 82. The transport plate 82 moves backward again to move the sub-assembly rack 70 on it away from the lifting platform.

[0015] See also Figure 3 The workbench 1 is also provided with two support platforms 85, which are opposite to each other and arranged on both sides of the transport plate 82. The support platform 85 is provided with a baffle 86 at one end away from the lifting platform, which is used to position and limit the sub-assembly rack 70 placed on the support platform 85. The workbench 1 is provided with a sub-assembly robot 19, which is provided with a sub-assembly finger cylinder for clamping the workpiece. After the transport plate 82 transports the sub-assembly rack 70 to the top of the support platform 85, it moves downward and places the sub-assembly rack 70 on the support platform 85 (such as Figure 5 As shown in FIG. 1 ), the transport plate 82 is separated from the sub-assembly rack 70, and the sub-assembly robot 19 inserts the workpieces one by one into the sub-assembly rack 70. During the process of the sub-assembly robot 19 placing the workpieces into the sub-assembly rack 70, the sub-assembly rack 70 is always placed on the support 85 instead of on the transport plate 82, which can reduce the load on the transport plate 82 and protect the transport device. Figure 1The transport plate 82 is provided with a protrusion 87 and a boss 88 protruding upward. The protrusion 87 and the boss 88 are positively opposite to each other along the moving direction of the transport plate 82, and the distance between the two is greater than the length of the sub-assembly rack 70. When the transport plate 82 transports the sub-assembly rack 70, the sub-assembly rack 70 is placed between the protrusion 87 and the boss 88. The protrusion 87 and the boss 88 limit the sub-assembly rack 70 to prevent the sub-assembly rack 70 from falling during the transport process. When the sub-assembly rack 70 is placed on the support platform 85, the protrusion 87 can push the sub-assembly rack 70 toward the baffle 86, so that the sub-assembly rack 70 is accurately positioned on the support platform 85. When the sub-assembly rack 70 on the pallet 85 is fully loaded with workpieces, the transport plate 82 moves upward to lift the sub-assembly rack 70, then moves forward to place the sub-assembly rack 70 back on the pallet assembly. During the placing back process, the boss 88 pushes the sub-assembly rack 70 toward the convex strip 79, so that the sub-assembly rack 70 is accurately positioned on the pallet assembly.

[0016] The following is a brief description of the working process of the utility model. First, the empty sub-packaging rack 70 is placed on the lifting platform, the transport plate 82 moves forward to the bottom of the sub-packaging rack 70, then moves upward to lift the bottom sub-packaging rack 70, and then moves backward to a position where the sub-packaging rack 70 is above the support platform 85, the transport plate 82 moves downward to place the sub-packaging rack 70 on the support platform 85, and at the same time the transport plate 82 moves backward to lower the baffle 86 of the sub-packaging rack 70, and then the transport plate 82 moves downward again to separate from the sub-packaging rack 70, and the sub-packaging robot 19 places the workpieces on the sub-packaging rack 70 one by one. After the sub-assembly rack 70 is fully loaded with workpieces, the transport plate 82 moves upward, holds up the sub-assembly rack 70, and then moves forward until the sub-assembly rack 70 is above the empty pallet group, and the transport plate 82 moves downward to place the sub-assembly rack 70 full of workpieces on the pallet group, and then the transport plate 82 moves backward to withdraw the lifting platform, and the lifting platform moves downward the distance between the two pallets, and the loading process of one sub-assembly rack is completed. Then repeat the above process, the sub-assembly racks on the entire lifting platform can be filled, the filled sub-assembly racks are taken out, the lifting platform moves upward, and then the empty sub-assembly racks are replaced, and another batch of sub-assembly racks can be loaded.

[0017] The utility model provides a workpiece packaging device. A conveying mechanism moves a packaging rack above the lifting platform from the lifting platform to a packaging position. After the packaging rack is filled with workpieces, the packaging rack is moved back to the lifting platform. The lifting platform moves downward, so that the empty packaging rack on the upper layer moves downward by the distance between two adjacent support plates. The conveying mechanism cooperates with the lifting platform to automatically fill the packaging rack above the lifting platform with workpieces one by one. The automation degree is high and the workpiece packaging efficiency is high.
