DETAILED DESCRIPTION
[0015] The specific implementation modes of the present utility model are further described in detail below.
[0016] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific implementation methods of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] The specific implementation of the utility model is further described in detail below in conjunction with the accompanying drawings.
[0018] The automatic feeding and trimming device for electronic components of the utility model comprises a pin trimming device and a feeding device cooperating with the pin trimming device, wherein the pin trimming device comprises a pin trimming table 21, a transfer table 22, and a double-arm gripper; the pin trimming table 21 is installed on the workbench 9, located between the feeding device and the transfer table 22, and the double-arm gripper is installed beside the pin trimming table 21.
[0019] like Figure 1As shown, the feeding device includes a pair of feeding support feet 12 installed on the workbench 1, a feeding slide rail 11 installed on the feeding support feet 12 and a bearing slider arranged on the feeding slide rail 11, a feeding table 13 that can be placed on the bearing slider and a bearing fixture 14 that can be placed on the feeding table 13, and the bearing fixture 14 is as shown in FIG. Figure 3 As shown, a plurality of carrying stations 17 are provided which match the shapes of the electronic components 16 to be inspected. The electronic components 16 to be inspected are placed on the carrying stations 17 with the surfaces with the pins to be trimmed facing downward.
[0020] The feeding device also includes a power device for pushing the carrying slider to advance step by step on the feeding slide rail 11, which is usually a cylinder driven by a stepping motor. The carrying slider is driven to slide on the feeding slide rail 11 in a stepping manner, each time sliding a distance of the length of the carrying station 17, pushing the electronic components to be inspected one by one to a position convenient for the robot to grab in the next step.
[0021] In a preferred embodiment, photoelectric sensor switches 15 are provided at both ends of the feed slide rail 11 to determine the reset origin when the load-bearing slide block is limited and reset.
[0022] In a preferred embodiment, infrared emitting and receiving devices are respectively provided at both ends of the feed slide rail 11, and the height of the horizontal emission of infrared rays is flush with the height of the electronic component 16 to be detected. When an electronic component 16 to be detected is placed on any carrying station 17, the horizontally emitted infrared rays will be blocked by the electronic component 16 to be detected. When there are no electronic components 16 to be detected on all the carrying stations 17, it means that all the components to be detected have entered the next process, and no new carrying tooling 14 with the electronic components 16 to be detected has been placed. The horizontally emitted infrared rays will be received by the receiving device, and the system will take corresponding actions according to the settings, such as stopping the operation of each component after a certain period of time, and sounding an alarm to remind the staff to load and replace the new electronic component 16 to be detected.
[0023] The electronic component automatic feeding and trimming device also includes a pin trimming device for performing a pin trimming process, which performs pin trimming processing on the electronic components 16 to be tested carried by the feeding device one by one, including a pin trimming table 21, a transfer table 22, and a double-arm gripper; the double-arm gripper has two mechanical arms, such as Figure 2 As shown, the pin trimming table 21 is installed on the workbench 1 and is located between the feeding device and the transfer table 22 , and the double-arm gripper is installed beside the pin trimming table 21 .
[0024] The one-dimensional linear motion of the two robotic arms can be controlled by separate cylinders, but in order to simplify the control method, by setting the distance between each device, the following overall motion method can be adopted.
[0025] The double-arm gripper has a first mechanical arm 23 and a second mechanical arm 24 mounted on a first horizontal slide rail 26; Figure 2 As shown, the first robotic arm 23 and the second robotic arm 24 are fixedly mounted at both ends of a robotic arm mounting plate 27, and the robotic arm mounting plate 27 is slidably mounted on a first horizontal slide rail 26. The robotic arm mounting plate 27 can be driven by a horizontal driving cylinder to translate along the first horizontal slide rail 26 to drive the two robotic arms to move as a whole. After the two robotic arms are fixed, the distance between them remains unchanged.
[0026] A pin trimming station 25 is provided in the center of the pin trimming table 21. By setting the positions of various devices, the distance between the carrying tool 14 on the feeding device and the pin trimming station 25, and the distance between the pin trimming station 25 and the transfer table 22 are equal to the distance S1 between the first robotic arm 23 and the second robotic arm 24.
[0027] The first robot arm 23 and the second robot arm 24 of the double-arm gripper are first translated along the first horizontal slide rail 26 to one end close to the feeding device, so that the first robot arm 23 is located just above a certain carrying station 17 on the carrying tooling 14. Due to the distance setting between the first robot arm 23 and the second robot arm 24, the second robot arm 24 is located just above the pin trimming station 25.
[0028] Then, the double-arm gripper controls the first mechanical arm 23 and the second mechanical arm 24 to descend simultaneously, and the gripper at the end simultaneously grabs the electronic component 16 to be inspected located at the carrying station 17 and the pin trimming station 25;
[0029] During the first operation, there is no trimmed electronic component on the pin trimming station 25 , and at this time, the second robot arm 24 has no electronic component to grab.
[0030] After the double-arm gripper completes grabbing of the electronic components near one end of the feeding device, the first mechanical arm 23 and the second mechanical arm 24 rise and translate along the first horizontal slide rail 26 by a distance S1 to one end away from the feeding device, so that the first mechanical arm 23 is just above the pin trimming station 25, and the second mechanical arm 24 is just above the transfer table 22. The double-arm gripper controls the first mechanical arm 23 and the second mechanical arm 24 to descend simultaneously to release the grabbed electronic components;
[0031] During the first operation, since there are no trimmed electronic components on the pin trimming station 25 , the second robot arm 24 has no electronic components to release onto the transfer table 22 .
[0032] The electronic components released by the first robot arm 23 to the pin trimming station 25 undergo pin trimming. While the pin trimming is being performed, the first robot arm 23 and the second robot arm 24 return to one end close to the feeding device and descend again to grab the electronic components, and this cycle is repeated.
[0033] Starting from the second operation process, the first robot arm 23 and the second robot arm 24 first grab the electronic components 16 to be inspected located on the carrying station 17 and the pin trimming station 25 at one end close to the feeding device, and then translate to the end away from the feeding device to release the grabbed electronic components onto the pin trimming station 25 and the transfer table 22 respectively.
[0034] At the same time, the feeding device needs to make a coordinated action. Since the first robot arm 23 only moves in one dimension along the first horizontal slide rail 26, when the first robot arm 23 grabs an electronic component on a certain carrying station 17, the feeding device needs to push the carrying slider to step forward on the feeding slide rail 11 by the distance of a carrying station 17, so that the next carrying station 17 with electronic components is advanced to the position of the carrying station 17 that has grabbed the electronic components, so that the first robot arm 23 can grab a new electronic component next time.
[0035] The pin trimming station 21 trims the pins of the electronic components placed on the pin trimming station 25. When the electronic components are placed on the carrying station 17, the side with the pins to be trimmed faces downward, and the first mechanical arm 23 does not flip the electronic components during the grabbing and releasing process, so that the pins of the electronic components are also facing downward when entering the carrying station 17. The pin trimming station 25 has a field-shaped hole below, so that the electronic components can be placed in the center of the field-shaped hole, and the pins can also be extended into the cutting cavity below the pin trimming station 25 through the field-shaped hole. A cross-shaped baffle is set in the center of the cutting cavity, and a tool is set around it. The tool moves from the surroundings of the cutting cavity to the center of the cutting cavity to cut the pins entering the pin trimming station 25. After cutting, the tool returns to the surroundings of the cutting cavity, and no clamping force is generated on the electronic components that have been cut. The above-mentioned pin trimming station is a prior art in the art. For example, the HF2806 cutting and drawing integrated machine produced by Dongguan Gengquan Mechanical Equipment Technology Co., Ltd. can be used as the pin trimming station 21.
[0036] After the pin trimming is completed, the electronic components have their excess irregular wires cut off, and all the pin ends are flush, ready for subsequent testing processes.
[0037] The automatic feeding and trimming device for electronic components of the utility model realizes automated operation of feeding and trimming pins, coordinates material transfer between the two processes of feeding and trimming pins by using a double-arm gripper, and improves trimming efficiency.
[0038] The foregoing describes various preferred embodiments of the utility model. If the preferred implementation modes in various preferred embodiments are not obviously self-contradictory or are based on a certain preferred implementation mode, various preferred implementation modes can be arbitrarily superimposed and used in combination. The embodiments and specific parameters in the embodiments are only for clearly describing the utility model verification process of the utility model owner, and are not used to limit the patent protection scope of the utility model. The patent protection scope of the utility model is still based on its claims. All equivalent structural changes made using the description and drawings of the utility model should be included in the protection scope of the utility model.
