[0032] As Figures 1 to 3 shown, this embodiment provides a tray transfer and loading device. The tray transfer and loading device is used to transfer the tray 100 to a specified station and sequentially load a plurality of workpieces 200 loaded on the tray 100. The present application does not limit the specific structures and shapes of the tray 100 and the workpieces 200. The drawings of this embodiment are only for illustration. The tray transfer and loading device includes a manipulator 1, a material picking component 2, and a material picking tray component 3. The material picking component 2 is connected to the manipulator 1, and the manipulator 1 can drive the material picking component 2 to move. The manipulator 1 imitates the movement of an arm and realizes the movement of the material picking component 2 according to a fixed program. The movement actions include but are not limited to horizontal movement, lifting movement, and spatial rotation. The structure and shape of the manipulator 1 in the drawings of this embodiment are only for illustration.

[0033] The material picking component 2 can sequentially pick up a plurality of workpieces 200 and transfer the plurality of workpieces 200 under the drive of the manipulator 1 to realize the loading action. The material picking component 2 includes a first air circuit mechanism 21. The air outlet end of the first air circuit mechanism 21 is connected to an external air source (not shown in the figure). The material picking tray component 3 can be selectively detachably connected to the material picking component 2. The material picking tray component 3 includes a first suction cup 31. The air inlet hole 311 of the first suction cup 31 can be connected to the air inlet end 211 of the first air circuit mechanism 21 to form a negative pressure air circuit. The first suction cup 31 is used to adsorb the tray 100. Through the detachable connection between the material picking tray component 3 and the material picking component 2, the manipulator 1 drives the material picking tray component 3 to move through the material picking component 2 to complete the material picking tray action, and the manipulator 1 drives the material picking component 2 to complete the loading action. Moreover, the first air circuit mechanism 21 of the material picking component 2 can enable the material picking tray component 3 to realize a negative pressure air circuit, and pick up the tray 100 through the suction action. The transfer of the tray 100 and the loading of the workpieces 200 are both realized through the manipulator 1 and the external air source, which simplifies the structure, improves the convenience of equipment maintenance, and thus reduces the production cost. Moreover, the tray transfer and loading device of this embodiment reduces the use of a set of power systems, does not occupy much production line space, and reduces the requirements for the space layout.

[0034] To improve the convenience of the connection between the material taking component 2 and the material taking tray component 3, the material taking component 2 includes a first magnetic attraction member 22, and the material taking tray component 3 includes a second magnetic attraction member. The first magnetic attraction member 22 can be magnetically connected to the second magnetic attraction member to achieve the magnetic connection between the material taking component 2 and the material taking tray component 3. Compared with other mechanical connection structures, magnetic connection has the advantages of quick connection and simple structure.

[0035] Optionally, one of the first magnetic attraction member 22 and the second magnetic attraction member is an electromagnet, and the material of the other is a ferromagnetic metal, such as iron, cobalt, nickel, and iron-containing alloys. The electromagnet generates a magnetic force when energized and adsorbs the ferromagnetic metal to achieve the quick magnetic connection between the material taking component 2 and the material taking tray component 3. When it is necessary to disconnect the material taking component 2 and the material taking tray component 3, just cut off the power supply of the electromagnet. The connection and disconnection of the material taking component 2 and the material taking tray component 3 are both quick and convenient. Exemplarily, as Figure 2 shown in the figure, the material taking component 2 is provided with a first magnetic attraction member 22, and the first magnetic attraction member 22 is an electromagnet; correspondingly, the material taking tray component 3 has a second magnetic attraction member made of a ferromagnetic metal.

[0036] One of the material taking component 2 and the material taking tray component 3 is provided with a positioning pin 32, and the other is provided with a positioning hole 23. The positioning pin 32 can be inserted into the positioning hole 23. Exemplarily, as Figure 3 shown in the figure, the material taking tray component 3 is provided with a plurality of positioning pins 32; correspondingly, a plurality of positioning holes 23 are formed on the material taking component 2. Through the insertion fit of the positioning pin 32 and the positioning hole 23, the accuracy of the relative position when the material taking component 2 and the material taking tray component 3 are connected is improved, the connection reliability between the first air circuit mechanism 21 and the first suction cup 31 is ensured, and air leakage is avoided.

[0037] The manipulator 1 drives the material taking component 2 to move and approach the material taking tray component 3. To guide the connection process between the material taking component 2 and the material taking tray component 3, one of the material taking component 2 and the material taking tray component 3 is provided with a guide post 34, and the other is provided with a guide groove 25. The guide post 34 can be inserted into the guide groove 25. The length of the guide post 34 extends along the first direction. The guide post 34 includes a limiting plane 341 parallel to the first direction, and the limiting plane 341 is used to abut against the inner wall of the guide groove 25 to limit the relative rotation between the material taking component 2 and the material taking tray component 3, further ensuring the accuracy of the relative position when the material taking component 2 and the material taking tray component 3 are connected. Exemplarily, as Figure 3 shown in the figure, the material taking tray component 3 is provided with a guide post 34; correspondingly, as Figure 2 shown in the figure, the material taking component 2 is provided with a guide groove 25.

[0038] In one embodiment, the material taking assembly 2 includes a first positioning platform 24, and the material taking tray assembly 3 further includes a second positioning platform 33. The positioning pin 32 and the guiding column 34 are both arranged on the second positioning platform 33, and the positioning hole 23 and the guiding groove 25 are both formed in the first positioning platform 24. Moreover, the air inlet end 211 of the first air circuit mechanism 21 is formed in the first positioning platform 24, and the air inlet hole 311 is formed in the second positioning platform 33. By making the first positioning platform 24 fit against the second positioning platform 33, the air inlet end 211 of the first air circuit mechanism 21 can be correspondingly communicated with the air inlet hole 311. At the same time, the positioning pin 32 can be inserted into the positioning hole 23. The planar abutment between the first positioning platform 24 and the second positioning platform 33 can improve the connection stability between the material taking assembly 2 and the material taking tray assembly 3, ensure the accurate relative positions of the positioning pin 32 and the positioning hole 23, and the accurate relative positions of the air inlet end 211 and the air inlet hole 311.

[0039] Optionally, the first magnetic part 22 is arranged inside the first positioning platform 24. Correspondingly, the second positioning platform 33 is made of ferromagnetic metal, which can simplify the structure. When the first positioning platform 24 and the second positioning platform 33 are abutted against each other, the first magnetic part 22 and the second magnetic part can complete the magnetic connection.

[0040] In one embodiment, the material taking tray assembly 3 further includes a bracket body 35 and a plurality of first suction cups 31, as Figure 4 and Figure 5 shown. The plurality of first suction cups 31 are arranged on the bracket body 35 at intervals to realize multi-point adsorption of the material tray 100, which is relatively reliable. The bracket body 35 is provided with a built-in second air circuit, and the second air circuit has a plurality of air outlet holes to communicate with the plurality of first suction cups 31 respectively. The other end of the second air circuit forms an air inlet hole 311 to communicate with the air inlet end 211 of the first air circuit mechanism 21, realizing the adsorption reliability of the plurality of first suction cups 31.

[0041] To facilitate the adsorption of the workpiece 200, the material taking assembly 2 further includes a lifting platform 26 and a second suction cup 27. The second suction cup 27 is arranged on the lifting platform 26 and is communicated with the first air circuit mechanism 21. The lifting platform 26 can drive the second suction cup 27 to reciprocate up and down along the first direction. Exemplarily, as Figure 1 shown, the first direction is the height direction of the material tray transfer and loading device. The second suction cup 27 is used to suck the workpiece 200. The bracket body 35 is provided with an avoidance notch 351. When the material taking assembly 2 is connected to the material taking tray assembly 3, the lifting platform 26 can pass through the avoidance notch 351 to avoid interference between the second suction cup 27 and the bracket body 35.

[0042] Optionally, the lifting platform 26 can elastically lift in the first direction, that is, there is an elastic part between the lifting platform 26 and the manipulator 1, avoiding excessive pressure when the second suction cup 27 abuts against the workpiece 200 and causing damage to the workpiece 200.

[0043] The tray transfer and loading device further includes a bearing bracket 4, which includes a bearing table 41 and a ballast member 42. The bearing table 41 is used to bear the material taking tray assembly 3. The ballast member 42 has a first working state of pressing against the material taking tray assembly 3 and a second working state of moving away from the material taking tray assembly 3 to avoid the material taking assembly 2. When the ballast member 42 is in the second working state, the material taking tray assembly 3 is in a movable free state, and the material taking assembly 2 can be connected to the material taking tray assembly 3. When the ballast member 42 is in the first working state, the movement of the material taking tray assembly 3 is restricted to ensure the position accuracy and facilitate the connection with the material taking assembly 2 next time.

[0044] Optionally, the ballast member 42 presses against the upper end surface of the guide post 34. The guide post 34 is guided and limited through the limiting plane 341, and the upper end surface is a non-working surface. The pressing friction of the ballast member 42 will not affect the performance of the guide post 34.

[0045] To realize the two working states of the ballast member 42, the bearing bracket 4 further includes a rotary pressing cylinder 43. The ballast member 42 is connected to the output shaft 431 of the rotary pressing cylinder 43. The output shaft 431 can rotate around the axis and reciprocate up and down in the first direction. The rotation of the output shaft 431 can realize the conversion of the ballast member 42 to the second working state, and the reciprocating up and down of the output shaft 431 in the first direction can realize the first working state of the ballast member 42 and the release of the first working state. The specific structure and working principle of the rotary pressing cylinder 43 can be set with reference to the prior art, and will not be elaborated in this embodiment.

[0046] In the tray transfer and loading device of this embodiment, during loading, first, the full tray 100 needs to be transferred to the working station. At this time, the manipulator 1 drives the material taking assembly 2 to move above the bearing bracket 4, and the ballast member 42 is converted from the first working state to the second working state. The manipulator 1 drives the material taking assembly 2 to magnetically connect to the material taking tray assembly 3. Subsequently, the manipulator 1 drives the material taking tray assembly 3 to move to the position of the full tray 100 through the material taking assembly 2. The first suction cup 31 of the material taking tray assembly 3 adsorbs the tray 100, and the manipulator 1 moves the full tray 100 to the working station through the material taking tray assembly 3 to realize the movement of the material taking tray. Then, the manipulator 1 drives the material taking assembly 2 and the material taking tray assembly 3 to move, and places the material taking tray assembly 3 on the bearing bracket 4. Subsequently, the magnetic connection between the material taking assembly 2 and the material taking tray assembly 3 is disconnected, and the ballast member 42 is converted to the first working state to press against the material taking tray assembly 3. The manipulator 1 drives the material taking assembly 2 to move to the working station, and the material taking assembly 2 starts to perform the loading operation of multiple workpieces 200 on the full tray 100 in sequence.

[0047] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
