Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, and in particular to a material tray conveying system and method thereof. Background Technology

[0002] The workflow of automated equipment can be divided into three actions: feeding, production, and discharging. By simulating manual operation, the equipment achieves automated production. Common rules for determining the discharging position in automated equipment include: 1. No judgment required: Finished products can be placed anywhere within a designated approximate area; 2. Sensor judgment: One or more sensors determine whether the discharging position is suitable for discharging; 3. Discharging position waiting to be discharged: The discharging position is paused, waiting for the product to be discharged before proceeding to the next station.

[0003] For products with high surface finish requirements and prone to defects, the entire process must be carried out within a tray. The tray's position on the production line is random and it moves continuously with the line; adjacent trays may travel side-by-side, or a single tray may travel alone. This operating method may prevent automated equipment from accurately determining the tray's position using traditional discharge position judgment rules, resulting in the equipment failing to complete the discharge process. Therefore, a new technical solution is needed to address these issues. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a material tray transfer system and method to solve the problem of inaccurate detection of the position of the material tray on the production line in the prior art.

[0005] To achieve the above and other related objectives, the present invention provides a material tray transfer system, specifically configured as follows: it includes a transfer component, a triggering component, and a material tray detection component, wherein the material tray is input to and / or output to a preset work position through the transfer component, and the triggering component is turned on and / or off by mechanical triggering of the material tray; when the material tray detection component is turned on, it detects whether the material tray has reached the preset work position.

[0006] Optionally, the triggering component includes a guide rod and a trigger switch. The two ends of the tray along the conveying direction are provided with protruding edges. When the protruding edges contact the guide rod and push the guide rod to rotate and squeeze the trigger switch, the trigger switch is triggered to start the detection component. When the protruding edges do not contact the guide rod, the guide rod separates from the trigger switch, and the trigger switch is triggered to stop the tray detection component from working.

[0007] Optionally, the guide rod includes a guide portion and a pressing portion. The guide portion is provided with a first guide slope and is connected to a first connecting plate via a rotating shaft. Under the guiding action of the first guide slope, the protruding edge pushes the guide portion to rotate around the axis of the rotating shaft, so as to lift the pressing portion and press the trigger switch.

[0008] Optionally, the tray detection assembly includes one or more tray detection elements, which are distributed along the conveying direction of the tray.

[0009] Optionally, the material tray detection components are set individually or in groups relative to each other.

[0010] Optionally, the system further includes a product detection component, which includes a first driving component and a product detection component connected to the driving end of the first driving component. When the tray arrives at the preset station, the first driving component drives the product detection component to approach the tray to detect whether there is a product in the tray. When the product detection component detects that there is a product in the tray, the first driving component drives the product detection component to move away from the tray to return to its original position, and the transmission component outputs the tray to the preset station.

[0011] Optionally, it also includes a tray blocking assembly, which includes a second driving member and a tray baffle connected to the driving end of the second driving member. When the product detection assembly detects that there is no product in the tray, the second driving member drives the tray baffle to move downward and lock the tray at the preset station.

[0012] Optionally, it also includes a feeding component. When the product detection component detects that there is no product in the tray and the tray baffle locks the tray at the preset station, the feeding component places the product into the tray. When the product detection component detects that there is a product in the tray, the second driving component drives the tray baffle to move upward to unlock the tray, and the transmission component outputs the tray to the preset station.

[0013] Optionally, the assembly also includes a tray guiding component, which includes a guide plate disposed on the transfer component for aligning the tray.

[0014] The present invention also provides a method for transferring a material tray, comprising the following steps:

[0015] The material tray triggers the triggering component to send a material tray detection signal via mechanical triggering.

[0016] The tray detection component receives the tray detection signal and detects whether the tray has reached the preset station.

[0017] Optionally, the tray triggers a triggering component to send a tray detection signal via mechanical triggering, including:

[0018] The protruding edge of the tray contacts the guide rod of the triggering component and pushes the guide rod to rotate. The protruding edge is located at both ends of the tray along the transmission direction.

[0019] The guide rod presses the trigger switch of the triggering component, sending out the material tray detection signal.

[0020] Optionally, after the material tray reaches the preset station, the following steps are further included:

[0021] Detect whether there is a product in the tray;

[0022] When a product is detected in the tray, the tray is output to the preset station;

[0023] When no product is detected in the tray, the tray is loaded with material, and the tray is then output from the preset station after loading is completed.

[0024] Optionally, the step of loading the material tray when no product is detected in the tray and outputting the loaded tray to a preset station includes the following steps:

[0025] Lock the tray in the preset work position;

[0026] Load the material into the tray;

[0027] Unlock the tray;

[0028] The material tray is output to the preset work station.

[0029] As described above, the material tray transfer system and method of the present invention have the following beneficial effects:

[0030] After the material tray enters the preset station via the transfer component, the triggering component activates the material tray detection component via mechanical triggering to detect whether the material tray has reached the preset station. This setup effectively avoids misjudgments in material tray position detection, improving its accuracy. The material tray detection component can accurately detect whether a single material tray has reached the preset station, ensuring smooth subsequent loading and / or unloading, and improving product yield. Furthermore, while achieving its functionality, this invention features a simple structure, is easy to manufacture, and reduces production costs. Attached Figure Description

[0047] Figure 1 This is a schematic diagram of the structure of a tray conveying system according to some embodiments of the present invention. Figure 2 Displayed as Figure 1 A partial structural diagram of the material tray conveying system. Figure 1 and Figure 2 As shown, this invention provides a tray conveying system, including a conveying component 2, a triggering component 3, and a tray detection component 4. The tray 1 is located on the conveying component 2 and inputs and / or outputs preset positions through the conveying component 2. The triggering component 3 mechanically activates and / or deactivates the tray detection component 4 via the tray 1 to detect whether the tray has reached the preset position. This configuration effectively avoids misjudgments in tray position detection by the tray detection component, improving the accuracy of tray position detection. The tray detection component can accurately detect whether a single tray has reached the preset position, ensuring smooth subsequent loading and / or unloading, and improving product yield.

[0048] like Figure 1 As shown, in some embodiments, the transmission component 2 includes a support 21 and a belt 22 connected to the support 21.

[0049] Specifically, the frame 21 is placed on the ground; the material tray 1 is placed on the belt 22 and moves together with the belt 22. The belt 22 drives the material tray to input and / or output preset stations.

[0050] Figure 3 This is a schematic diagram of the structure of a triggering component according to some embodiments of this application. For example... Figure 3 As shown, in some embodiments, the triggering component 3 includes a first support plate 31 connected to the frame 21 of the transmission component 2. The first support plate 31 is connected to a guide rod 33 and a second connecting plate 35 via a first connecting plate 32. A micro switch 36 is connected to the second connecting plate 35, and the micro switch 36 is provided with a contact 361.

[0051] In some embodiments, the protruding edge contacts the guide rod 33, pushing the guide rod 33 to rotate and press the contact 361 of the trigger switch 36, triggering the trigger switch 36 to start the detection assembly 4; when the protruding edge does not contact the guide rod 33, the guide rod 33 separates from the contact 361, triggering the trigger switch 36 to stop the tray detection assembly 4 from working.

[0052] It should be noted that the protruding edges are located at both ends of the material tray 1 along the conveying direction.

[0053] Figure 4 This is a schematic diagram of the guide rod structure according to some embodiments of this application. For example... Figure 4 As shown, in some embodiments, the guide rod 33 includes a guide portion 331 and a pressing portion 332. The guide portion 331 is provided with a first guide slope 3311, and the guide portion 331 is connected to the first connecting plate 32 through a rotating shaft 34. Under the guidance of the first guide slope 3311, the protrusion pushes the guide portion 331 to rotate around the axis of the rotating shaft 34, so as to lift the pressing portion 332 to press the trigger switch 36, so that the trigger switch 36 triggers the material tray detection assembly 4 to work.

[0054] Specifically, when the protruding edge at the front end of the material tray 1 moves to contact the first guide slope 3311 of the guide rod 33, under the guidance of the first guide slope 3311, the material tray 1 gradually lifts the pressing part 332 of the guide rod 33. The guiding part 331 of the guide rod 33 rotates around the axis of the rotating shaft 34, causing the pressing part 332 to continuously approach the contact point 361. Finally, the pressing part 332 presses the contact point 361, triggering the micro switch 36 to open the material tray detection assembly 4 to detect whether the material tray 1 has reached the preset position. When the pressing part 332 enters the inner cavity of the material tray 1 from the protruding edge at the front end of the material tray 1, the pressing part 332 separates from the contact point 361, triggering the micro switch 36 to close the material tray detection assembly 4.

[0055] In some embodiments, the feeding time of the feeding component depends on the length of the extrusion section 332. When the length of the extrusion section 332 is increased, the contact time between the extrusion section 332 and the contact 361 is extended, that is, the feeding time of the feeding component is extended; when the length of the extrusion section 332 is shortened, the connection time between the extrusion section 332 and the contact 361 is shortened, that is, the feeding time of the feeding component is shortened.

[0056] In some embodiments, when the extrusion part 332 contacts the contact 361, it remains parallel to the bottom surface of the inner cavity of the tray 1, ensuring that the extrusion part 332 and the contact 361 are always connected.

[0057] In some embodiments, the second connecting plate 35 is provided with multiple sets of threaded holes connected to the micro switch 36, so as to facilitate the adjustment of the relative position of the micro switch 36 on the second connecting plate 35, thereby adjusting the contact time between the contact 361 and the extrusion part 332. During the contact time between the contact 361 and the extrusion part 332, the feeding assembly can feed the material into the material tray 1.

[0058] In some embodiments, a boss is provided on the first support plate 31, and a groove is provided on the first connecting plate 32 to mate with the boss. The boss of the first support plate 31 is embedded in the groove of the first connecting plate 32, so that the first support plate 31 and the first connecting plate 32 are tightly connected. Furthermore, due to the provision of the boss and the groove, the relative position of the first support plate 31 and the first connecting plate 32 is stable.

[0059] In some other embodiments, a micro switch 36 and a guide rod 33 that contacts or separates from the contacts 361 of the micro switch 36 are provided on the first support plate 31, which simplifies the structure and reduces manufacturing costs.

[0060] In some embodiments, the tray detection assembly 4 includes three tray detection elements 42, which are connected to the frame 21 of the transmission assembly 2 via a third connecting plate 41. The tray detection elements 42 are distributed along the transmission direction of the tray 1 and the detection surface of the tray detection elements 42 faces the tray 1.

[0061] Specifically, at the connection between the guide section 331 and the extrusion section 332, two parallel tray detection elements 42 are arranged near the position of the frame 21. These elements are used to detect whether the front of the tray 1 has reached the preset station, avoiding misjudgment of the position of the tray 1 at the input preset station when the distance between the front and rear of the tray 1 at the output and input preset stations is less than or equal to the length of the extrusion section 332. A tray detection element 42 is arranged at the rear of the preset station, with the distance between the foremost and rearmost elements being less than the length of the tray 1. This element is used to detect whether the rear of the tray 1 has reached the preset station. When the microswitch 36 activates the tray detection assembly 4, all three tray detection elements 42 simultaneously begin detecting the tray 1. If all three elements 42 detect the tray 1 simultaneously, it indicates that the tray 1 has reached the preset station; if any one of the three elements 42 fails to detect the tray 1, it indicates that the tray 1 has not reached the preset station.

[0062] In some other embodiments, the number of tray detectors 42 in the detection assembly can be set to 1, 2, 4 or even more. The tray detectors 42 are distributed along the conveying direction of the tray 1 so as to detect the position of the tray 1 in the conveying assembly 1 by the tray detectors 42.

[0063] In some embodiments, the tray detection element 42 is a photoelectric sensor, which can be selected as through-beam, specular reflection, or diffuse reflection, preferably through-beam or specular reflection, which is beneficial for more accurate detection of the tray's position in the device.

[0064] Figure 5 This is a schematic diagram of the structure of a product testing component according to some embodiments of this application. For example... Figure 5 As shown, in some embodiments, the product testing component 5 includes a second support plate 51 connected to the frame 21 of the transmission component 2, a first drive member 53 connected to the second support plate 51 via a fourth connecting plate 52, and a first adapter plate 54 connected to the drive end of the first drive member 53. The product testing component 56 is connected to the first adapter plate 54 via the second adapter plate 55.

[0065] In some embodiments, the detection surface of the product detection element 56 faces the side of the tray 1 where the product is placed, in order to detect whether there is a product in the tray 1.

[0066] In some other embodiments, a first driving member 53 is provided on the second support plate 51, and the driving end of the first driving member 53 is connected to a second adapter plate 55, which simplifies the structure and reduces manufacturing costs.

[0067] In some embodiments, the first drive member 53 is a cylinder.

[0068] In some embodiments, the product detection element 56 is a photoelectric sensor, which can be selected as through-beam, specular, or diffuse reflection, preferably diffuse reflection, which is beneficial for detecting whether there is a product in the area where the product is placed on the tray.

[0069] In some implementations, when the tray 1 reaches the preset station, the first drive unit 53 drives the product detection unit 56 to move downwards and approach the tray 1 to detect whether there is a product in the tray 1. When the product detection unit 56 detects a product in the tray 1, the first drive unit 53 drives the product detection unit 56 to move upwards and away from the tray 1 to return to its original position, and the transmission component 2 outputs the tray 1 with the product to the preset station.

[0070] Figure 6 This is a schematic diagram of the structure of a tray blocking assembly according to some embodiments of this application. For example... Figure 6 As shown, in some embodiments, the tray blocking assembly 6 spans above the tray 1 and is connected to the frame 21 of the transmission assembly 2 via a connecting rod 61, so that the tray baffle 66 can lock the tray 1.

[0071] In some embodiments, the tray blocking assembly 6 is located at the front of the preset station. In other embodiments, the tray blocking assembly 6 is located at the rear of the preset station.

[0072] In some embodiments, the tray blocking assembly 6 includes a second driving member 63 connected to the connecting rod 61 via a third support plate 62 and a third adapter plate 64 connected to the driving end of the second driving member 63, and the tray baffle 66 is connected to the third adapter plate 64 via a fourth adapter plate 65.

[0073] In some implementations, when the product detection component 56 detects that there is no product in the tray 1, the second drive component 63 drives the tray baffle 66 downward to lock the tray 1 at a preset position, preventing the tray 1 from moving forward; when the feeding component feeds the tray, and the product detection component 56 detects that there is a product in the tray 1, the second drive component 63 drives the tray baffle 66 upward to unlock the tray 1, and the transmission component 2 outputs the tray 1 with the product to the preset position.

[0074] In some embodiments, the third adapter plate 64 and the fourth adapter plate 65 are connected by screws for easy disassembly and adjustment. In other embodiments, the third adapter plate 64 and the fourth adapter plate 65 are welded together for a more robust structure.

[0075] In some embodiments, the tray blocking assembly 6 further includes a guide assembly 67 connected to the third support plate 62, and the guide assembly 67 is connected to the third adapter plate 64. The guide assembly 67 provides support and guidance during the upward or downward movement of the tray baffle 66, while reducing the force on the second drive member 63 and improving the service life of the second drive member 63.

[0076] In some embodiments, the guide component 67 is a linear guide.

[0077] In some implementations, to make the upward or downward movement of the tray baffle 66 more stable, the guide assembly 67 is provided with two sets of linear guides.

[0078] In some embodiments, the tray blocking assembly 5 further includes a limiting plate 58 located below the third support plate 62 and connected to the connecting rod 61.

[0079] Specifically, when the second driving component 63 drives the tray baffle 66 to descend, when the tray baffle 66 descends to the preset position, the limiting plate 58 and the fourth adapter plate 65 are tightly fitted together, preventing the tray baffle 66 from continuing to descend. This achieves the function of mechanically limiting the downward position of the tray baffle 66, avoiding collision between the tray baffle 66 and the tray 1 during the descent process, which would damage the tray 1 and increase the production cost of the product.

[0080] In an exemplary embodiment, the tray conveying system may further include a tray guide assembly 7, which is located on one side of the belt 22 and aligns the trays on the belt 22, which is beneficial for subsequent inspection of the trays 1.

[0081] In some embodiments, the tray guide assembly 7 is mounted on the frame 21 of the transfer assembly 2, and the trigger assembly 3, the tray detection assembly 4, the product detection assembly 5, and the tray blocking assembly 6 are all mounted on the tray guide assembly 7.

[0082] In some embodiments, the tray guide assembly 7 includes a fifth connecting plate 71 connected to the frame 21 of the transfer assembly 2 and a guide plate 72 connected to the fifth connecting plate 71.

[0083] In some embodiments, the guide plate 72 is provided with a second guide ramp 721 to guide and align the tray 1.

[0084] In some implementations, a guide plate 72 is provided after the material tray 1 enters the work station to straighten the material tray 1, so that the material trays 1 entering the area of ​​the material tray detection component 3 are arranged in a straight line in sequence, ensuring the accuracy of the material tray detection component 3 in detecting the specific position of the material tray 1.

[0085] Embodiments of this application also provide a tray transfer method, which may include the following steps:

[0086] Step S1: The material tray 1 triggers the triggering component 3 to send a material tray detection signal.

[0087] In some embodiments, the tray 1 is located on the belt 22 and moves with the belt 22. During the movement, the tray 1 comes into contact with the trigger component 3, triggering the trigger component 3 to send out a tray detection signal.

[0088] Step S2: The material tray detection component 4 receives the material tray detection signal and detects whether the material tray 1 has reached the preset station.

[0089] In some embodiments, after receiving the tray detection signal, the tray detection component 4 starts its working mode and detects whether the tray 1 has reached the preset station through the tray detection element 42. When all tray detection elements 42 detect the tray 1, it is determined that the tray 1 has reached the preset station.

[0090] In an exemplary embodiment, step S1, in which the material tray 1 triggers the triggering component 3 to send a material tray detection signal, may include steps S11 to S12.

[0091] Step S11: The protruding edge of the material tray 1 contacts the guide rod 33 of the trigger component 3 and pushes the guide rod 33 to rotate. The protruding edge is set at both ends of the material tray 1 along the transmission direction.

[0092] In some embodiments, the tray 1 moves forward with the belt 22, and the protruding edge at the front end of the tray 1 contacts the first guide slope 3311 of the guide rod 33. Under the guidance of the first guide slope 3311, the protruding edge pushes the guide rod 33 to rotate.

[0093] Step S12: The guide rod 33 presses the trigger switch of the trigger assembly 3 and sends out a material tray detection signal.

[0094] In some embodiments, the extrusion section 332 of the guide rod 33 extrudes the trigger switch of the trigger assembly 3 and sends out a tray detection signal.

[0095] In one exemplary embodiment, the tray transfer method may further include the following steps:

[0096] Step S3: Check if there is a product in tray 1.

[0097] In some embodiments, the first drive 53 in the product detection component 5 drives the product detection component 56 downward toward the tray 1 to detect whether there is a product in the tray 1.

[0098] Step S4: When a product is detected in tray 1, tray 1 is output to the preset station.

[0099] In some embodiments, when the product detection component 56 detects a product in the tray 1, the first driving component 53 drives the product detection component 56 to move upward away from the tray 1 to return to its original position, and the transmission component 2 outputs the tray 1 with the product to the preset station.

[0100] Step S5: When no product is detected in the material tray 1, the material tray 1 is loaded and the material tray after loading is output to the preset station.

[0101] In some embodiments, when the product detection component 56 detects that there is no product in the tray 1, the feeding component feeds the tray, and the transmission component 2 outputs the tray 1 with the product to the preset station.

[0102] In an exemplary embodiment, step S5, when it is detected that there are no products in the tray, loads the tray and outputs the tray after loading to the preset station, may include steps S51 to S54.

[0103] Step S51: Lock the material tray 1 in the preset work position.

[0104] In some embodiments, the second drive member 63 of the tray blocking assembly 6 drives the tray baffle 66 downward to lock the tray 1 at a preset position and prevent the tray 1 from moving forward.

[0105] Step S52: Load material into tray 1.

[0106] In some embodiments, the feeding component feeds the material tray 1.

[0107] Step S53: Unlock tray 1.

[0108] In some embodiments, the second drive member 63 of the tray blocking assembly 6 drives the tray baffle 66 upward to unlock the tray 1.

[0109] Step S54: Output material tray 1 to the preset station.

[0110] In some embodiments, the transfer component 2 outputs the tray 1 containing the product to a preset workstation.

[0111] In summary, the present invention provides a tray conveying system and method. After the tray enters the preset station through the conveying component, the triggering component activates the tray detection component via mechanical triggering to detect whether the tray has reached the preset station. This design effectively avoids misjudgments in tray position detection by the tray detection component, improving its accuracy. The tray detection component can accurately detect whether a single tray has reached the preset station, ensuring smooth subsequent loading and / or unloading, and improving product yield. Furthermore, while achieving its functionality, the present invention has a simple structure, is easy to process, and reduces manufacturing costs.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
