[0034] The utility model will be further explained in detail in combination with the drawings.

[0035] Please refer to Figures 1 to 2 A transfer device provided by the utility model embodiment is used in cooperation with a processing equipment, which comprises a base 100, a hinged assembly 200 and a loading assembly 300. The loading assembly 300 is located above the base 100, and the loading assembly 300 comprises a loading platform 330, a first supporting arm 310 and a second supporting arm 320; the starting end of the first supporting arm 310 and the starting end of the second supporting arm 320 are both connected to the bottom of the loading platform 330 and are arranged at intervals; the hinged assembly 200 comprises a first connecting rod 210, a second connecting rod 220, a third connecting rod 230 and a fourth connecting rod 240; the starting end of the first connecting rod 210 and the starting end of the second connecting rod 220 are both connected to the base 100 at intervals and are arranged at intervals in the left-right direction; the end of the first connecting rod 210 is hinged to one end of the third connecting rod 230, and the end of the second connecting rod 220 is hinged to the other end of the third connecting rod 230. The starting end of the fourth connecting rod 240 is hinged to the central position of the second connecting rod 220 in the length direction and is inclined to the direction away from the first connecting rod 210 of the second connecting rod 220. The end of the first supporting arm 310 is rotatably connected to the central position of the third connecting rod 230 in the length direction, and the end of the fourth connecting rod 240 is rotatably connected to the end of the second supporting arm 320. When the first connecting rod 210 and the second connecting rod 220 rotate in the same direction, the third connecting rod 230 and the fourth connecting rod 240 drive the loading platform 330 to slide horizontally to switch between the loading position and the unloading position.

[0036] The loading position refers to the position where the worker places the article on the loading platform 330, and the unloading position refers to the position where the worker needs to transfer the article from the loading platform 330 to the processing equipment.

[0037] In a specific application, the worker pushes the carrier 330 to slide left or right, the first connecting rod 210 and the second connecting rod 220 rotate left or right, the third connecting rod 230 rotates relative to the first connecting rod 210 and the second connecting rod 220, and moves left or right with the first connecting rod 210 and the second connecting rod 220 to support the carrier 330 moving left or right; at the same time, the fourth connecting rod 240 is connected between the second connecting rod 220 and the second support arm 320, and the fourth connecting rod 240 rotates relative to the second connecting rod 220 and the carrier 330 under the action of the second connecting rod 220 to assist the third connecting rod 230 to support the carrier 330 upward. Wherein, the third connecting rod 230 and the fourth connecting rod 240 are connected with the first support arm 310 and the second support arm 320 respectively to support the position of the carrier 330 in the left and right directions, so that the carrier 330 can be kept in a horizontal state to avoid the carrier 330 from turning over.

[0038] It can be understood that when the third connecting rod 230 rotates relative to the first connecting rod 210 and the second connecting rod 220, the height of the middle position of the third connecting rod 230 changes little, that is, the height of the connection position with the first support arm 310 changes little, and it is about 1-4cm up and down. Therefore, when the carrier 330 slides from the loading position to the unloading position, the height of the carrier 330 changes little, so that the carried articles can be transported to the required position, for example, the transfer device can accurately transport the machine tool jig to the required position of the processing equipment, thereby reducing the strength of the worker, and the worker only needs to transport the articles to the carrier 330 at the loading position, effectively ensuring the safety of the worker.

[0039] In one form of application, referring to Figure 1 and Figure 3 When the carrier 330 is at the loading position, the first connecting rod 210 coincides with the third connecting rod 230, that is, both rotate to the vertical state of the same straight line, the second connecting rod 220 is inclined to the first connecting rod 210, and the fourth connecting rod 240 rotates to the vertical state.

[0040] Referring to Figure 1 and Figure 5 When the carrier 330 is at the unloading position, the second connecting rod 220 coincides with the third connecting rod 230, that is, both rotate to the vertical state of the same straight line, the first connecting rod 210 is inclined to the second connecting rod 220, and the fourth connecting rod 240 is inclined to the side of the second connecting rod 220 away from the first connecting rod 210. It can be understood that the first connecting rod 210 and the second connecting rod 220 can both rotate to the vertical state, so that the carrier 330 can slide left or right to a larger distance, thereby ensuring that the carrier 330 has a large enough sliding distance between the loading position and the unloading position, thereby ensuring that the carrier 330 can transfer the articles to the required position.

[0041] In a specific structural form, the first connecting rod 210 and the second connecting rod 220 are of equal length and are arranged to be inclined relative to each other. Figure 1 and Figure 4 When the platform 330 is at the center between the loading position and the unloading position, the third connecting rod 230 is in a horizontal state, the first connecting rod 210 tilts leftward toward the second connecting rod 220, and the second connecting rod 220 tilts rightward toward the first connecting rod 210. In other possible embodiments, the first connecting rod 210 and the second connecting rod 220 can also be arranged in a parallel structure.

[0042] In practice, if the first connecting rod 210 rotates leftward and downward, the second connecting rod 220 rotates leftward and upward; if the first connecting rod 210 rotates rightward and upward, the second connecting rod 220 rotates rightward and downward. During this process, the longitudinal middle position of the third connecting rod 230 remains approximately at the corresponding height, ensuring that the height of the carrier 330 remains approximately constant when it slides from the loading position to the unloading position, thereby ensuring that the items can be transferred to the desired location.

[0043] Further, refer to Figure 1 and Figure 2 ,from Figure 4 When observing the transfer device from a perspective, when the carrier 330 is between the loading position and the unloading position, the first connecting rod 210 and the second connecting rod 220 are intersecting. In other possible embodiments, the first connecting rod 210 and the second connecting rod 220 may also be arranged to be non-intersecting. It is understood that within a limited distance between the first connecting rod 210 and the second connecting rod 220, the first connecting rod 210 can be tilted as far to the left as possible and the second connecting rod 220 can be tilted as far to the right as possible, and the first connecting rod 210 and the second connecting rod 220 have a long length. Therefore, when the first connecting rod 210 rotates to the right, the first connecting rod 210 can drive the carrier 330 to move a sufficient distance to the right, and when the second connecting rod 220 rotates to the left, the second connecting rod 220 can drive the carrier 330 to move a sufficient distance to the left. As a result, the carrier 330 can move a sufficient distance from the loading position to the unloading position, thereby transporting the items on the carrier 330 to the desired location.

[0044] In some embodiments, the length of the fourth link 240 is half the length of the second link 220, and the middle position of the first link 210 is rotatably connected to the starting end of the fourth link 240. With this arrangement, the fourth link 240 can be adapted to the left and right movement of the motion support platform 330 of the second link 220, but the fourth link 240 is not limited to being arranged only with the above-mentioned size requirements.

[0045] In some embodiments, reference Figure 1 and Figure 2, the hinged assembly 200 is provided with two groups, and the first connecting rod 210, the second connecting rod 220, the third connecting rod 230, the fourth connecting rod 240, the first support arm 310 and the second support arm 320 are each provided with two. The hinged assembly 200 further comprises a first lower rotating shaft 2010, a second lower rotating shaft 2020, a first middle rotating shaft 250, a second middle rotating shaft 260, a third middle rotating shaft 270, a third middle rotating shaft 270 and a fourth middle rotating shaft 280. Among them, the first lower rotating shaft 2010 is rotatably arranged on the base 100, and the two ends of the first lower rotating shaft 2010 are rotatably connected with the two ends of the first lower rotating shaft 2010. The second lower rotating shaft 2020 is rotatably arranged on the base 100, and the two ends of the second lower rotating shaft 2020 are rotatably connected with the two ends of the second lower rotating shaft 2020. The first middle rotating shaft 250 is rotatably connected between the two ends of the first connecting rod 210, the second middle rotating shaft 260 is rotatably connected between the two ends of the second connecting rod 220, and the two ends of the first middle rotating shaft 250 are rotatably connected with the two ends of the second middle rotating shaft 260. One end of the third middle rotating shaft 270 is rotatably connected with the middle position of one of the third connecting rods 230, and the other end of the third middle rotating shaft 270 is rotatably connected with the middle position of the other third connecting rod 230. One end of the fourth middle rotating shaft 280 is rotatably connected with the middle position of one of the second connecting rods 220, and the other end is rotatably connected with the middle position of the other second connecting rod 220. The two ends of the fourth middle rotating shaft 280 are rotatably connected with the two ends of the fourth connecting rod 240. The two ends of the fourth middle rotating shaft 280 are rotatably connected with the two ends of the fourth connecting rod 240. The two second support arms 320 are rotatably connected with the two ends of the fourth middle rotating shaft 280.

[0046] Among them, the length of the first middle rotating shaft 250 is less than the length of the second middle rotating shaft 260, and is less than or equal to the distance between the two second connecting rods 220, so that the two first connecting rods 210 can pass through the space between the two second connecting rods 220 to intersect with the second connecting rod 220. The above scheme is implemented.

[0047] It can be understood that the hinged assembly 200 is provided with two groups, and the first middle rotating shaft 250 and the second middle rotating shaft 260 are arranged between the two groups. In this way, the two groups of hinged assemblies 200 are more convenient to install and connect through the first middle rotating shaft 250 and the second middle rotating shaft 260, and can stably support the loading platform 330, so as to stably transfer the articles to the required position.

[0048] In some embodiments, referring to Figure 1 With Figure 2, the first connecting rod 210 is provided with a first notched portion 211 on the side away from the second connecting rod 220, for example, the first connecting rod 210 has a bent portion bent towards the second connecting rod 220, and the first connecting rod 210 forms the first notched portion 211 at the bent portion for embedding the second transfer shaft 260. In specific applications, when the loading position of the loading platform 330, the first connecting rod 210 and the third connecting rod 230 are in a vertical state and overlap each other, the second transfer shaft 260 is embedded in the first notched portion 211 and retained in the first notched portion 211, so that the first connecting rod 210, the second connecting rod 220 and the third connecting rod 230 can be kept in the corresponding state, so that the loading platform 330 can be stably kept in the loading position, and then the staff can conveniently carry the articles to the loading platform 330.

[0049] In some embodiments, referring to Figure 1 With Figure 2 , the first support arm 310 is provided with a second notched portion 311 on the side away from the second support arm 320 for embedding the second transfer shaft 260. In specific applications, when the loading position of the loading platform 330, the second connecting rod 220 and the third connecting rod 230 are in a vertical state and overlap each other, the second transfer shaft 260 is embedded in the second notched portion 311 and retained in the second notched portion 311, so that the first connecting rod 210, the second connecting rod 220 and the third connecting rod 230 can be kept in the corresponding state, so that the loading platform 330 can be stably kept in the loading position, and then the staff can conveniently carry the articles to the loading platform 330.

[0050] In some embodiments, referring to Figure 1 With Figure 2 , in the direction from the loading position to the unloading position, the loading platform 330 is divided into a first loading area 331 and a second loading area 332, and the first loading area 331 is located on the left side of the second loading area 332. The first support arm 310 and the second support arm 320 are connected to the bottom of the second loading area 332, for example, the first support arm 310 is connected to the bottom of the first loading area 331 away from the second loading area 332, and the second support arm 320 is connected to the bottom of the first loading area 331 close to the second loading area 332, more specifically, the second support arm 320 is connected to the bottom of the middle position of the loading platform 330. It can be understood that the first support arm 310 and the second support arm 320 are connected to the part of the loading platform 330 close to the loading position, so that the loading platform 330 extends to the unloading position in a sufficient length, or in other words, the second loading area 332 has a sufficient extension length to the left side, so that in applications, the second loading area 332 has a sufficient length to extend into the processing equipment, so that the articles can be conveniently transferred into the processing equipment.

[0051] Instead of manually pushing the carrier 330 to slide left and right, in some embodiments, the transfer device further comprises a driving assembly 400 for driving the first link 210 and / or the second link 220 to rotate, for example, the driving assembly 400 is used to drive the second link 220 to rotate, so as to drive the carrier 330 to switch between the loading position and the unloading position.

[0052] In a specific embodiment, referring to Figure 1 With Figure 6 , the driving assembly 400 comprises a sliding seat 420, a driving member 410 and a transmission link 430, wherein the sliding seat 420 is slidably arranged on the base 100 in the left-right direction, and the driving member 410 is used to drive the sliding seat 420 to slide left and right, wherein the driving member 410 can adopt a motor screw structure, a pneumatic cylinder, etc. One end of the transmission link 430 is rotatably connected with the sliding seat 420, and the other end is rotatably connected with the first link 210 or the second link 220.

[0053] In other possible embodiments, the driving assembly 400 can also adopt a pneumatic cylinder, an electric push rod, etc. to directly drive the second link 220 to rotate.

[0054] In specific applications, the driving member 410 drives the sliding seat 420 to slide left and right, and the sliding seat 420 drives the second link 220 to rotate left or right through the transmission link 430, the first link 210 and the second link 220 rotate left or right in the same direction, the third link 230 rotates relative to the first link 210 and the second link 220, and moves left or right with the first link 210 and the second link 220, thereby driving the carrier 330 to switch between the loading position and the unloading position; at the same time, the fourth link 240 is rotatably connected between the second link 220 and the second support arm 320, and the fourth link 240 rotates relative to the first link 210 and the second support arm 320 under the action of the second link 220, to assist the third link 230 to drive the carrier 330 to move left and right, so that the carrier 330 switches between the loading position and the unloading position, thereby conveniently transporting the articles to the required position.

[0055] The application also provides a processing system comprising a processing device, a robot and the above-mentioned transfer device, the robot is arranged in the processing device, and the transfer device is arranged on one side of the processing device.
