[0023] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] like Figures 1-9 As shown, this embodiment provides a workpiece assembly device, which includes a frame 100, a docking assembly 200, a bearing mechanism 300, and a robotic arm 400. The docking assembly 200 is mounted on the frame 100 and includes a docking base 210, a docking mechanism 220, and a guiding mechanism 230. The docking base 210 is mounted on the frame 100 and can hold a first workpiece and a second workpiece arranged at intervals in the front-back direction. The docking mechanism 220 is mounted on the docking base 210, and its docking part can approach or move away from the first workpiece. When it approaches the first workpiece, it can push the second workpiece to make it insert and cooperate with the first workpiece to form an assembly. The guiding mechanism 230 is mounted on the docking base 210, and the guide member 231 of the guiding mechanism 230 has a guiding channel 2311. The guiding channel 2311 is used to guide the docking part of the docking mechanism 220 and guide the second workpiece to approach the first workpiece. The bearing mechanism 300 is used to bear the first workpiece and can also bear the assembly. The output end of the robotic arm 400 is used to adsorb the first workpiece and the assembly, and moves back and forth between the bearing mechanism 300 and the docking base 210 under the driving action of the robotic arm 400.

[0028] The above setup improves automation and reduces the labor intensity of workers. Under the guidance of the guide channel 2311 of the guide mechanism 230, the docking part of the docking mechanism 220 and the guide second workpiece move along a standardized path as they approach the first workpiece. This helps guide the second workpiece to accurately fit into the first workpiece, thus avoiding misalignment and damage. At the same time, accurate docking helps ensure a good connection between the two, improves the accuracy of testing, reduces the probability of reduced yield due to poor contact, and avoids waste caused by false rejection.

[0029] In addition, since the bearing mechanism 300 can carry both the first workpiece and the assembly, the robotic arm 400 has no idle stroke during its reciprocating motion between the bearing mechanism 300 and the docking base 210, which improves the utilization rate of the equipment and effectively improves work efficiency with only one robotic arm 400. At the same time, there is no need to set up a separate storage structure for the assembly, which reduces the footprint of the equipment.

[0030] In this embodiment, the first workpiece is the product 1000 to be tested, which can be a PCB. The second workpiece is the test board 2000, which, after being connected to the PCB, can be connected to the testing equipment to complete the testing of the PCB. For ease of description, the following description will use the test board 2000 as the second workpiece and the product 1000 as the first workpiece.

[0031] Regarding the specific implementation of the docking mechanism 220, in some embodiments, the docking mechanism 220 includes a docking drive component 221 and a docking component 222. The docking drive component 221 is disposed on the docking base 210, and its output end can approach or move away from the product 1000. The docking component 222 is disposed at the output end of the docking drive component 221. The docking drive component 221 is a linear module, which helps to ensure the reliability of its output end during movement.

[0032] To avoid damage to product 1000 or test board 2000 due to excessive force during the mating process, in some embodiments, the mating mechanism 220 further includes a mating buffer 223. The mating buffer 223 is disposed between the output end of the mating drive 221 and the mating member 222 to buffer the driving force of the mating drive 221. The mating buffer 223 is capable of elastic deformation, thereby buffering the output force of the mating drive 221.

[0033] For example, the docking mechanism 220 further includes docking guide rods 224, the docking buffer 223 includes a spring, the output end of the docking drive 221 is provided with a docking connecting plate 2211, the docking connecting plate 2211 is provided with a guide hole, the docking guide rod 224 is slidably disposed in the guide hole, and one end of the docking guide rod 224 is fixedly connected to the docking member 222, the spring is sleeved in the guide hole, and both ends abut against the docking member 222 and the docking connecting plate 2211 respectively. There are two docking guide rods 224 and two guide holes, with the two docking guide rods 224 respectively passing through the two guide holes.

[0034] In some embodiments, the docking component 222 includes a docking seat 2221 and a mating connector 2222. One end of the docking guide rod 224 is fixedly connected to the docking seat 2221. The mating connector 2222 is disposed on the docking seat 2221 and includes a head connection portion 22221 and a docking arm 22222 protruding from the head connection portion 22221. The docking portion is disposed at the end of the docking arm 22222 facing the product 1000. The docking component 222 is divided into a docking seat 2221 and a mating connector 2222, which makes the processing of the mating connector 2222 more convenient and allows for individual replacement according to different test plate 2000 models, reducing costs. At the same time, the materials of the mating connector 2222 and the docking seat 2221 can be different. The docking seat 2221 is made of metal to ensure strength, while the mating connector 2222 can be made of hard rubber to reduce the probability of scratching the test plate 2000 when in contact with it.

[0035] Since the test plate 2000 and the product 1000 to be tested are connected by a plug-in joint, a certain amount of friction needs to be overcome during the plug-in process to ensure the connection effect and prevent loosening. Therefore, the plate-shaped test plate 2000 may tend to bend during its forward movement. Once bent, the friction between the test plate 2000 and the product 1000 will further increase, potentially making further plugging impossible. This could lead to misalignment and breakage of the test plate 2000 and the docking arm 22222 during the continued forward movement of the mating section, or damage to the plug groove of the product 1000.

[0036] To avoid the aforementioned problems, a pressing block 22223 protrudes from the end of the docking arm 22222 facing the product 1000. The lower sidewall of the pressing block 22223 forms a pressing part to restrict the test plate 2000 from bending upwards. The pressing block 22223 not only restricts the test plate 2000 from bending upwards, but also prevents the test plate 2000 from separating from the docking arm 22222 after bending, ensuring that the test plate 2000 moves forward smoothly.

[0037] During the forward movement of the connector 2222, in order to ensure that the test plate 2000 smoothly enters the area below the crimping block 22223 and abuts against the end of the mating arm 22222, the crimping block 22223 is provided with a first guide slope 22224 at the end facing the product 1000. The first guide slope 22224 is inclined upward in the direction close to the product 1000.

[0038] Furthermore, the docking arm 22222 includes a base and a protrusion. The base is located between the protrusion and the connecting portion 22221, and the outer diameter of the base is larger than that of the protrusion. The end face of the protrusion away from the base forms the docking portion. A pressing block 22223 is provided on the protrusion. The base ensures the strength of the docking arm 22222, which is a cantilever structure, while the protrusion makes the machining of the docking portion easier and reduces costs. Simultaneously, since the test plate 2000 and the product 1000 are stacked vertically, this arrangement ensures that when the test plate 2000 is installed on the product 1000, the protrusion is located on the upper side of the product 1000, and the base is located on the rear side of the product 1000, avoiding interference.

[0039] In some embodiments, the guiding mechanism 230 includes a guiding drive 232, which is disposed on the docking seat 2221. Its output shaft extends perpendicular to the insertion direction between the test plate 2000 and the product 1000 and is arranged to rotate about its own axis. The guide 231 is disposed at the output end of the guiding drive 232 and rotates synchronously with it. Under the driving action of the guiding drive 232, the guide 231 can press the product 1000 against the docking seat 2221 or be located outside the path of the product 1000 moving to the docking base 210. This arrangement fixes the relative position of the product 1000 and the docking seat 2221, preventing positional shifts during the insertion of the test plate 2000 and ensuring the insertion effect. The docking seat 2221 is provided with at least two positioning pins, which can be correspondingly inserted into at least two positioning holes in the product 1000.

[0040] During the guiding process, there is friction between the lower sidewall of the test plate 2000 and the guide member 231. To prevent the guide member 231 from being moved by the test plate 2000 and affecting the guiding effect, in some embodiments, the guide member 231 is provided with a fixing hole, and the docking base 210 is provided with a fixing pin 211. When the guide member 231 is pressed against the product 1000, the fixing pin 211 is inserted into the fixing hole. The extension direction of the fixing pin 211 is perpendicular to the insertion direction of the test plate 2000 and the product 1000, thus ensuring the positional stability of the guide member 231 during the movement of the test plate 2000 along the guide member 231, thereby guaranteeing its guiding effect. The base 210 is provided with at least two fixing pins 211, which are spaced apart in the left and right direction. The guide 231 is provided with at least two fixing holes, which correspond one-to-one with the at least two fixing pins 211. This ensures that the guide 231 remains in the same position relative to the base 210 after being subjected to the friction force of the test plate 2000, thereby ensuring the guiding effect and facilitating the smooth entry of the test plate 2000 into the insertion slot.

[0041] Furthermore, the docking base 210 is provided with a receiving groove, in which the product 1000 is placed. The front sidewall of the receiving groove forms a front stop to block the product 1000, preventing the product 1000 from moving forward and affecting the insertion effect during the insertion of the test board 2000 into the insertion groove. The front stop is a planar structure that fully limits the product 1000, ensuring that the position of the product 1000 relative to the docking base 210 remains unchanged during the insertion of the test board 2000, thereby ensuring that the test board 2000 smoothly enters the insertion groove. In addition, the design of the receiving groove allows its outline to serve as the edge for placing the product 1000 when taking pictures from above, thus playing a positioning role. A camera is provided at the end of the robotic arm 400 for shooting and positioning.

[0042] In some embodiments, the rear end of the docking base 210 is provided with two guide blocks 212 spaced apart in the left-right direction. The top surface of the guide block 212 forms a support surface 2121, and the support surface 2121 protrudes upward to form a guide wall 2122. The opposing surfaces of the two guide walls 2122 form two guide surfaces 2123. When the guide member 231 presses against the product 1000, it presses against at least part of the top of the guide wall 2122, and the support surface 2121, the guide surface 2123, and the bottom surface of the guide member 231 form a guide channel 2311. The guide member 231 can both press against the product 1000 and serve as a guide structure, so that the relative position between the pressed product 1000 and the guide member 231 can be accurately guaranteed, which helps to guide the test plate 2000 into the insertion slot of the product 1000 more accurately. The bottom surface of the guide member 231 is provided with a second guide slope 2312. The second guide slope 2312 is inclined downward along the direction in which the test plate 2000 enters the insertion slot of the product 1000. In other words, the second guide slope 2312 is inclined forward and downward.

[0043] A sliding groove is formed between the two guide blocks 212. The sliding groove is connected to the guide channel 2311 and is located below the guide channel 2311. The docking arm 22222 can slide along the sliding groove. This arrangement reduces the weight of the docking base 210 on the one hand, and on the other hand, it ensures the outer diameter of the docking arm 22222, preventing it from being too small, which helps to ensure the strength of the docking arm 22222.

[0044] To accommodate test plates 2000 of different widths, at least one of the two guide blocks 212 is movably disposed on the docking base 210 in the left-right direction, so that the distance between the two guide surfaces 2123 is adjustable, thereby accommodating test plates 2000 of different widths. Specifically, the guide block 212 is provided with an adjustment hole extending in the left-right direction, and the docking base 210 is provided with an adjustment screw hole, through which an adjustment screw passes and can be screwed into the adjustment screw hole.

[0045] To further improve assembly efficiency, in some embodiments, the docking assembly 200 further includes a material frame 240 and a transfer assembly 250. The material frame 240 is disposed on the docking base 210 and is used to support the test plate 2000. The front end of the guide channel 2311 extending in the front-rear direction is connected to the insertion slot of the product 1000. The rear end of the support surface 2121 is provided with a limiting wall 2124, and the front end of the limiting wall 2124 forms a limiting surface 2125. The transfer assembly 250 is used to transfer the second workpiece in the material frame 240 to the support surface 2121, and is limited on the left and right sides of the second workpiece by two guide surfaces 2123 respectively, and on the rear side of the second workpiece by the limiting surface 2125. This arrangement enables the transfer of the test plate 2000 to be automated, further reducing the labor intensity of workers while improving assembly efficiency. The transfer assembly 250 includes a transfer drive 251, a transfer lifting component 252, and a transfer adsorption component 253. The transfer drive 251 is located on the docking base 210, and its output end moves back and forth in the left and right direction and is connected to the transfer lifting component 252. The output end of the transfer lifting component 252 can move back and forth in the up and down direction and is connected to the transfer adsorption component 253. The transfer adsorption component 253 can adsorb or release the test plate 2000.

[0046] The material frame 240 has a receiving cavity for accommodating the test plate 2000, and its bottom is provided with a lifting channel communicating with the receiving cavity. The material lifting drive 241 is located on the docking base 210, and its output end is located in the lifting channel of the material frame 240, and can move back and forth in the up and down direction so that when the transfer component 250 picks up the material, the height of the uppermost test plate 2000 in the material frame 240 remains unchanged, which facilitates the transfer component 250 to adsorb the test plate 2000.

[0047] The supporting mechanism 300 includes a supporting support 310 and a material picking assembly 320. The supporting support 310 is provided with a feeding bin 311 and a receiving bin 312. The material picking assembly 320 includes a material picking drive 321, a lifting drive 322 and a lifting member 323. The output end of the material picking drive 321 can move between the feeding bin 311, the receiving bin 312 and the feeding position, and is connected to the lifting drive 322 in a transmission manner. The output end of the lifting drive 322 can reciprocate in the vertical direction and is connected to the lifting member 323 in a transmission manner. In use, the lifting drive 321 moves the lifting drive 322 and the lifting member 323 to the feeding bin 311. Then, the lifting drive 322 actuates, causing the lifting member 323 to lift the carrier carrying the product 1000 in the feeding bin 311. The support member 331 on the side wall of the feeding bin 311 retracts under the drive of the support drive 332, the lifting member 323 descends, and then the support member 331 extends and stops the second carrier from bottom to top. Under the action of the picking drive 321, the carrier is moved to the feeding position. The robotic arm 400 can pick up the product 1000 from the carrier located at the feeding position and move the product 1000 to the docking base 210. The vertical direction is the up-down direction.

[0048] It should be noted that the robotic arm 400 places the finished product into the carrier located at the feeding position. When the carrier at the feeding position is full of finished products, the material handling component 320 places the carrier into the receiving bin 312.

[0049] In some embodiments, the feeding bin 311 is located between the feeding position and the receiving bin 312.
