Description

Technical Field

[0001] The present invention belongs to the technical field of automation equipment, and in particular relates to a multi-streamline carrier changing machine. Background Art

[0002] Production line carriers refer to auxiliary tools used to carry, protect and transport products or parts during the manufacturing process. They play a vital role in modern production lines, not only improving production efficiency but also ensuring the stability and consistency of product quality.

[0003] In conventional production lines, it is generally necessary to continuously place empty carriers at the starting position of the production line so that the loading equipment can place the product raw materials in the carriers for transportation. At the same time, the carriers need to be taken out at the end of the production line to avoid carrier blockage in the middle of the production line due to the accumulation of carriers in the production line, which makes it impossible for the carriers to flow to various workstations for processing or testing. Therefore, a large number of carriers need to be stocked at the starting position of the production line, and a large number of carriers are also piled up at the end of the production line, resulting in a large number of carrier resources being idle and a large amount of space being required to store idle carriers. Summary of the invention

[0004] The purpose of the present invention is to provide a multi-streamline carrier changing machine to solve the technical problems described in the background technology.

[0005] The multi-streamline carrier changing machine includes a frame, on which are installed a new tool return conveyor line, a new tool upper conveyor line, an old tool return conveyor line, an old tool upper conveyor line, a product information identification module, a material unloading module, a carrier handling module and an NG product conveyor line. The end of the new tool return conveyor line is connected to the head end of the new tool upper conveyor line so that the new tool return conveyor line supplies new carriers to the new tool upper conveyor line, the end of the new tool upper conveyor line is connected to the head end of the production line, and the head end of the old tool return conveyor line is connected to the end of the production line so that the production line can convey the products in the carriers to the old ones after processing or testing them. The product information identification module is used to identify the carrier on the old tool return conveyor line to obtain product information. The unloading module determines whether to take out the product in the carrier according to the product information. The end of the old tool return conveyor line is connected to the head end of the old tool upper conveyor line, and the end of the old tool upper conveyor line is connected to the new tool upper conveyor line. When the product in the carrier is taken out by the unloading module, the carrier on the old tool return conveyor line is transported to the new tool upper conveyor line through the old tool upper conveyor line. When the product in the carrier is not taken out by the unloading module, the carrier transport module transports the carrier to the NG product conveyor line for delivery.

[0006] According to the technical solution, the present invention can achieve the following beneficial effects:

[0007] 1. After each workstation on the production line completes processing or testing of the product in the carrier, the production line will convey the carrier to the old tool return conveyor line. At this time, the product information identification module identifies the carrier on the old tool return conveyor line and obtains product information to find out whether the product in the carrier meets the quality standards. If the product in the carrier meets the quality standards, the unloading module will take out the product in the carrier. After that, the carrier on the old tool return conveyor line is conveyed to the new tool upper conveyor line through the old tool upper conveyor line. At this time, the carrier is conveyed to the production line by the new tool upper conveyor line for recycling. Therefore, there is no need to stock a large number of new carriers at the starting position of the production line. At the same time, a large number of carriers will not be piled up and stored at the end of the production line, thereby reducing the idle resources of the carriers and preventing a large number of idle carriers from occupying a large amount of space.

[0008] 2. If the production line transports the carrier to the old tool return conveyor line, and the product in the carrier does not meet the quality standards, the carrier handling module will move the carrier to the NG product conveyor line so that another production line can perform post-processing on the products that do not meet the quality standards.

[0009] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.

[0010] In some embodiments, a new tool blocking mechanism is provided at the end of the new tool return conveyor line, and an old tool blocking mechanism is provided at the connection between the old tool upper conveyor line and the new tool upper conveyor line. When the new tool return conveyor line supplies new carriers to the new tool upper conveyor line, the old tool blocking mechanism blocks the old tool upper conveyor line from conveying the old carriers to the new tool upper conveyor line. When the old tool upper conveyor line conveys the old carriers to the new tool upper conveyor line, the new tool blocking mechanism blocks the new tool return conveyor line from supplying new carriers to the new tool upper conveyor line.

[0011] According to the technical solution, it is avoided that the new tool return conveyor line and the old tool upper conveyor line simultaneously provide the conveying carrier of the new tool upper conveyor line to cause conflict and blockage.

[0012] In some embodiments, when the carrier transport module transports the carrier to the NG product conveyor line and sends it away, the new mold return conveyor line supplies new carriers to the new mold upper conveyor line;

[0013] According to the technical solution, the present invention can further achieve the following beneficial effects:

[0014] 1. As the carrier is sent to another production line by the NG product conveyor line along with the products that do not meet the quality standards, the upper conveyor line of the new mold will lack a carrier to supply the original production line. At this time, the new mold return conveyor line supplies new carriers to the upper conveyor line of the new mold, thereby avoiding the number of carriers that should be lacking in the original production line and reducing work efficiency;

[0015] 2. Another production line connected to the NG product conveyor line can be provided with another unloading module and connected to the new mold return conveyor line, so that after the products that do not meet the quality standards are taken out from the carrier, the carrier can be conveyed to the new mold return conveyor line, thereby realizing the recycling of the carrier.

[0016] In some embodiments, a loading module is also installed on the frame, and the loading module is used to transport the product to a carrier located on the upper conveyor line of the new tool;

[0017] According to the technical solution, when the upper conveyor line of the new tool transports the carrier to the production line, the product to be processed or tested can be placed in the carrier in advance, thereby omitting the process of the product line and improving the efficiency of the production line.

[0018] In some embodiments, the upper conveyor line for new tools is located above the return conveyor line for new tools, and a new tool lifting module is provided at the end of the return conveyor line for new tools, and the new tool lifting module is used to transport the carrier from the return conveyor line for new tools to the upper conveyor line for new tools; the upper conveyor line for old tools is located above the lower return conveyor line for old tools, and an old tool lifting module is provided at the end of the lower return conveyor line for old tools, and the old tool lifting module is used to transport the carrier from the lower return conveyor line for old tools to the upper conveyor line for old tools;

[0019] According to the technical solution, the present invention can further achieve the following beneficial effects:

[0020] 1. Since the upper conveyor line of the new tool is vertically stacked and arranged above the return conveyor line of the new tool, at the same time, the upper conveyor line of the old tool is also vertically stacked and arranged above the lower return conveyor line of the old tool, the floor space of the multi-streamline change carrier machine can be reduced;

[0021] 2. The setting of the new tool lifting module can connect the upper conveyor line of the new tool with the return conveyor line of the new tool at different heights. In addition, the setting of the old tool lifting module can also connect the upper conveyor line of the old tool with the lower return conveyor line of the old tool at different heights.

[0022] In some embodiments, the product information identification module includes a light spot emitter and a photosensitive element. The product in the carrier is provided with a product light-transmitting sheet extending outside the carrier. The product light-transmitting sheet can block a portion of light. The light transmittance between the product light-transmitting sheets on each product is different. The light spot emitter is used to illuminate the light spot. The light spot passes through the product light-transmitting sheet and illuminates the photosensitive element. When the light spot passes through the product light-transmitting sheet, the product light-transmitting sheet blocks a portion of the brightness of the light spot. The photosensitive element obtains the information of each product and locates each product according to the brightness of the light spot.

[0023] According to the technical solution, the present invention can further achieve the following beneficial effects:

[0024] 1. Since the light transmittance of the product translucent sheet can be infinitely selected, that is, the brightness and darkness behind the light spot translucent product translucent sheet can be infinite, therefore, the product number can be given according to the brightness and darkness of the light spot;

[0025] 2. Since the photosensitive element obtains the information of each product according to the brightness of the light spot, that is, the photosensitive element can immediately obtain the product information at the moment when the brightness of the light spot changes, therefore, compared with conventional barcode readers, it can effectively improve the efficiency of information acquisition;

[0026] 3. Since the light spot emitter irradiates the light spot to the photosensitive element, when the brightness of the light spot changes, it can be determined that the product has moved to the position of the photosensitive element, thereby obtaining the information of the product and locating the product;

[0027] 4. Since the light transmittance of each product is different, the photosensitive element can locate a specific product based on the characteristic brightness of the light spot;

[0028] 5. Since the light spot can pass through the product light-transmitting sheet, it is possible to allow the product light-transmitting sheet to pass through product light-transmitting sheets of different heights, thereby realizing the positioning of products at different heights and obtaining information about products at different heights, so as to improve the efficiency of positioning and obtaining product information, and it is possible to obtain information on multiple products and locate multiple products through a set of components, thereby reducing the size of the equipment and the manufacturing cost of the equipment.

[0029] In some embodiments, a laser engraving machine for engraving the light-transmitting sheet of the product to different light transmittances is installed on the frame;

[0030] According to the technical solution, after the loading module places the product to be processed or tested on the carrier, the product translucent sheet on the product is engraved to different specific transmittances by a laser engraving machine, so that the product can obtain a unique code according to the product translucent sheet with different transmittances.

[0031] In some embodiments, the light transmittance of the product light-transmitting sheet is set in a gradient, and the gradient range between the product light-transmitting sheets on each product is different;

[0032] According to the technical solution, the present invention can further achieve the following beneficial effects:

[0033] 1. Since the light transmittance of the product light-transmitting sheet is set to a gradual setting, and the light spot changes dynamically when the product light-transmitting sheet passes between the photosensitive element and the light spot emitter, the photosensitive element can obtain product information through all the specific light and dark values ​​of the light spot when it changes dynamically;

[0034] 2. Since the gradient ranges between the product translucent sheets on each of the products are different, when the product translucent sheets at different heights overlap, the transmittances of the product translucent sheets at different heights are also superimposed. At this time, the transmittance of the translucent sheet of one product can be obtained by subtracting the transmittance of the translucent sheet of another product from the total transmittance, and finally the product information at different heights can be obtained.

[0035] In some embodiments, the light spot emitter emits at least two separate light spots, and when the light spots pass through two different heights and the product transparent sheet moves, the photosensitive element locates the products at two different heights according to the size and brightness difference between the two separate light spots;

[0036] According to the technical solution, the present invention can further achieve the following beneficial effects:

[0037] Since it is impossible to achieve absolute vertical alignment between the light-transmitting sheets of products at different heights, a light spot emitter can be used to illuminate at least two separate light spots. When the light spots pass through two light-transmitting sheets of products at different heights and in motion, the photosensitive element determines the heights at which the two products are located based on the size and brightness difference between the two separate light spots.

[0038] In some embodiments, the gradient ranges between the product light-transmitting sheets on each product do not overlap;

[0039] According to the technical solution, overlapping conflicts of gradient ranges between light-transmitting sheets on different products can be avoided to reduce positioning accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] like Figures 1 to 5 As shown, this specific embodiment provides a multi-streamline carrier changing machine, which includes a frame 1, on which are installed a new tool return conveyor line 2, a new tool upper conveyor line 21, an old tool return conveyor line 3, an old tool upper conveyor line 31, a product information recognition module 4, a material unloading module 33, a carrier handling module 34 and an NG product conveyor line 35. The end of the new tool return conveyor line 2 is connected to the head end of the new tool upper conveyor line 21, so that the new tool return conveyor line 2 supplies new carriers to the new tool upper conveyor line 21, the end of the new tool upper conveyor line 21 is connected to the head end of the production line, and the head end of the old tool return conveyor line 3 is connected to the end of the production line, so that the production line completes processing or testing of the product in the carrier and then conveys it to the old tool return conveyor line 3. The product information recognition module 4 is used to identify the carrier on the old tool return conveyor line 3 to obtain product information. The product information recognition module 4 can The barcode scanner is used, and the unloading module 33 determines whether to take out the product in the carrier according to the product information. The end of the old tool return conveyor line 3 is connected to the head end of the old tool upper conveyor line 31. The end of the old tool return conveyor line 3 can be provided with a carrier lifting mechanism that lifts the carrier to the head end of the old tool upper conveyor line 31, so as to realize the connection between the end of the old tool upper conveyor line 31 and the new tool upper conveyor line 21. The carrier lifting mechanism can be driven by a screw module to move the conveyor belt to the end of the old tool return conveyor line 3 or the head end of the old tool upper conveyor line 31 for splicing. When the product in the carrier is taken out by the unloading module 33, the carrier on the old tool return conveyor line 3 is transported to the new tool upper conveyor line 21 through the old tool upper conveyor line 31. When the product in the carrier is not taken out by the unloading module 33, the carrier transport module 34 transports the carrier to the NG product conveyor line 35 for delivery.

[0049] After each workstation on the production line completes processing or testing of the product in the carrier, the production line will convey the carrier to the old tool return conveyor line 3. At this time, the product information identification module 4 identifies the carrier on the old tool return conveyor line 3 and obtains product information to find out whether the product in the carrier meets the quality standards. If the product in the carrier meets the quality standards, the unloading module 33 will take out the product in the carrier. Thereafter, the carrier on the old tool return conveyor line 3 is conveyed to the new tool upper conveyor line 21 through the old tool upper conveyor line 31. At this time, the carrier is conveyed to the production line by the new tool upper conveyor line 21 for recycling. Therefore, there is no need to stock a large number of new carriers at the starting position of the production line. At the same time, a large number of carriers will not be piled up and stored at the end of the production line, thereby reducing the idle resources of the carriers and preventing a large number of idle carriers from occupying a large amount of space.

[0050] If the production line conveys the carrier to the old tool return conveyor line 3, and the product in the carrier does not meet the quality standards, the carrier transport module 34 will transport the carrier to the NG product conveyor line 35 and send it away, so that another production line can perform post-processing on the products that do not meet the quality standards.

[0051] In some embodiments, a new tool blocking mechanism 22 is provided at the end of the new tool return conveyor line 2. When the old tool upper conveyor line 31 conveys the old carrier to the new tool upper conveyor line 21, the new tool blocking mechanism 22 blocks the new tool return conveyor line 2 from supplying the new carrier to the new tool upper conveyor line 21. The old tool blocking mechanism 32 can achieve blocking by pushing the block to move by the cylinder; an old tool blocking mechanism 32 is provided at the connection between the old tool upper conveyor line 31 and the new tool upper conveyor line 21. When the new tool return conveyor line 2 supplies the new carrier to the new tool upper conveyor line 21, the old tool blocking mechanism 32 blocks the old tool upper conveyor line 31 from conveying the old carrier to the new tool upper conveyor line 21. The new tool blocking mechanism 22 can achieve blocking by pushing the block to move by the cylinder. Therefore, it can be avoided that the new tool return conveyor line 2 and the old tool upper conveyor line 31 simultaneously supply carriers to the new tool upper conveyor line 21, causing conflict and blockage.

[0052] In some embodiments, when the carrier transport module 34 transports the carrier to the NG product conveyor line 35 for delivery, the new mold return conveyor line 2 supplies new carriers to the new mold upper conveyor line 21 .

[0053] Since the carrier is sent to another production line by the NG product conveyor line 35 along with the products that do not meet the quality standards, the upper conveyor line 21 of the new mold will lack a carrier to supply the original production line. At this time, the new mold return conveyor line 2 supplies new carriers to the upper conveyor line 21 of the new mold, thereby avoiding the original production line from lacking the number of carriers and thus reducing work efficiency.

[0054] Another production line connected to the NG product conveyor line 35 can be provided with another unloading module 33 and connected to the new mold return conveyor line 2, so that after the products that do not meet the quality standards are taken out from the carrier, the carrier can be conveyed to the new mold return conveyor line 2, thereby realizing the recycling of the carrier.

[0055] In some embodiments, a loading module 23 is also installed on the frame 1. The loading module 23 is used to transport the product to a carrier located on the upper conveyor line 21 of the new tool. The loading module 23 can realize a conventional clamp module or suction cup module that can move horizontally, vertically and up and down.

[0056] When the new tool upper conveyor line 21 transports the carrier to the production line, the product to be processed or tested can be placed in the carrier in advance, thereby omitting the process of the product line and improving the efficiency of the production line.

[0057] In some embodiments, the new tool upper conveyor line 21 is located above the new tool return conveyor line 2, and a new tool lifting module is provided at the end of the new tool return conveyor line 2. The new tool lifting module is used to transport the carrier from the new tool return conveyor line 2 to the new tool upper conveyor line 21. The new tool lifting module can be a conventional lifting pallet, clamp mechanism, suction cup mechanism and robotic arm, etc. The old tool upper conveyor line 31 is located above the old tool lower return conveyor line, and an old tool lifting module is provided at the end of the old tool lower return conveyor line. The old tool lifting module is used to transport the carrier from the old tool lower return conveyor line to the old tool upper conveyor line 31. The old tool lifting module can be a conventional lifting pallet, clamp mechanism, suction cup mechanism and robotic arm, etc.

[0058] Since the upper conveyor line 21 of the new tool is vertically stacked and arranged above the return conveyor line 2 of the new tool, and at the same time, the upper conveyor line 31 of the old tool is also vertically stacked and arranged above the lower return conveyor line of the old tool, the floor space of the multi-streamline carrier machine can be reduced;

[0059] The setting of the new tool lifting module can connect the new tool upper conveyor line 21 and the new tool return conveyor line 2 at different heights. In addition, the setting of the old tool lifting module can also connect the old tool upper conveyor line 31 and the old tool lower return conveyor line at different heights.

[0060] In some embodiments, the product information identification module 4 includes a light spot emitter 41 and a photosensitive element 42. The product in the carrier is provided with a product light-transmitting sheet 43 extending outside the carrier. The product light-transmitting sheet 43 extends to a point where it will not be blocked by the new tool return conveyor line 2, the new tool upper conveyor line 21, the old tool return conveyor line 3, the old tool upper conveyor line 31, the NG product conveyor line 35 and the conveyor line on the product. The product light-transmitting sheet 43 can block part of the light. The transmittance of the product light-transmitting sheets 43 on each product is different. The light spot emitter 41 is used to illuminate the light spot 44. The light spot 44 passes through the product light-transmitting sheet 43 and illuminates the photosensitive element 42. When the light spot 44 passes through the product light-transmitting sheet 43, the product light-transmitting sheet 43 blocks part of the brightness of the light spot 44. The photosensitive element 42 obtains the information of each product and locates each product according to the brightness of the light spot 44.

[0061] Since the light transmittance of the product light-transmitting sheet 43 can be infinitely selected, that is, the brightness of the light spot 44 through the product light-transmitting sheet 43 can be infinite, the product number can be given by the brightness of the light spot 44. In addition, since the photosensitive element 42 obtains the information of each product according to the brightness of the light spot 44, that is, the photosensitive element 42 can immediately obtain the product information at the moment when the brightness of the light spot 44 changes, therefore, compared with conventional barcode readers, the information acquisition efficiency can be effectively improved.

[0062] Furthermore, since the light spot emitter 41 irradiates the light spot 44 to the photosensitive element 42, when the brightness of the light spot 44 changes, it can be determined that the product has moved to the position of the photosensitive element 42, thereby obtaining the information of the product and locating the product. In addition, since the light transmittance of the product transparent sheet 43 on each product is different, the photosensitive element 42 can locate a specific product based on the characteristic brightness of the light spot 44.

[0063] Furthermore, since the light spot 44 can pass through the product light-transmitting sheet 43, that is, the product light-transmitting sheet 43 can pass through product light-transmitting sheets 43 of different heights, it is possible to locate products at different heights and obtain information about products at different heights, thereby improving the efficiency of positioning and obtaining product information, and being able to obtain information on multiple products and locate multiple products through a set of components, thereby reducing the size of the equipment and the manufacturing cost of the equipment.

[0064] In some embodiments, a laser engraving machine 24 for engraving the product light-transmitting sheet 43 to different light transmissivities is installed on the frame 1 .

[0065] After the loading module 23 places the product to be processed or tested on the carrier, the laser engraving machine 24 engraves the product light-transmitting sheet 43 on the product to different specific light transmittances, so that the product can obtain a unique code according to the product light-transmitting sheet 43 with different light transmittances. The power and engraving time of the laser engraving machine 24 can be controlled to achieve different light transmittances.

[0066] In some embodiments, the light transmittance of the product light-transmitting sheet 43 is set in a gradient, and the gradient range of the product light-transmitting sheet 43 on each product is different.

[0067] Since the transmittance of the product light-transmitting sheet 43 is set to be gradually changed, and when the product light-transmitting sheet 43 passes between the photosensitive element 42 and the light spot emitter 41, the light spot 44 also changes dynamically, therefore, the photosensitive element 42 can obtain product information through all specific light and dark values ​​of the light spot 44 when it changes dynamically; in addition, since the gradient ranges between the product light-transmitting sheets 43 on each of the products are different, therefore, when the product light-transmitting sheets 43 at different heights overlap, the transmittances of the product light-transmitting sheets 43 at different heights are also superimposed. At this time, the transmittance of one product light-transmitting sheet 43 can be obtained by subtracting the transmittance of another product light-transmitting sheet 43 from the total transmittance, and finally the product information at different heights can be obtained.

[0068] In some embodiments, the light spot emitter 41 emits at least two separate light spots 44 . When the light spots 44 pass through two different heights and the moving product transparent sheet 43 , the photosensitive element 42 locates the products at two different heights according to the size and brightness difference between the two separate light spots 44 .

[0069] Since it is impossible to achieve absolute vertical alignment between the light-transmitting sheets 43 of products at different heights, the light spot emitter 41 can be used to illuminate at least two separate light spots 44. When the light spots 44 pass through the light-transmitting sheets 43 of the products at two different heights and move, the photosensitive element 42 determines at which height the two products are located based on the size and brightness difference between the two separate light spots 44.

[0070] In some embodiments, the gradient ranges of the product light-transmitting sheets 43 on each product do not overlap, thereby avoiding overlapping conflicts of the gradient ranges of the product light-transmitting sheets 43 on different products and reducing the positioning accuracy.

[0071] In order to further illustrate the multi-streamline carrier changing machine described in this specific embodiment, the following examples are listed first. Example

[0072] like Figures 1 to 4As shown, this embodiment provides a multi-streamline carrier changing machine, which includes a frame 1. The frame 1 is equipped with a new tool return conveyor line 2, a new tool upper conveyor line 21, a loading module 23, an old tool return conveyor line 3, an old tool upper conveyor line 31, a product information identification module 4, a unloading module 33, a carrier handling module 34 and an NG product conveyor line 35.

[0073] The upper conveyor line 21 for new tools is located above the return conveyor line 2 for new tools. The end of the return conveyor line 2 for new tools is provided with a new tool lifting module, which is used to transport the carrier from the return conveyor line 2 for new tools to the upper conveyor line 21 for new tools, so that the end of the return conveyor line 2 for new tools is connected to the head end of the upper conveyor line 21 for new tools. The return conveyor line 2 for new tools supplies new carriers to the upper conveyor line 21 for new tools. The end of the return conveyor line 2 for new tools is provided with a new tool blocking mechanism 22, and the end of the upper conveyor line 21 for new tools is connected to the head end of the production line, so that the upper conveyor line 21 for new tools can transport the carrier above it to the production line. The loading module 23 is used to transport the product to the carrier located on the upper conveyor line 21 for new tools.

[0074] The head end of the old tool return conveyor line 3 is connected to the end of the production line so that the production line can convey the products in the carrier to the old tool return conveyor line 3 after processing or testing. The product information identification module 4 is used to identify the carrier on the old tool return conveyor line 3 to obtain product information. The product information identification module 4 is a code scanning module, and the carrier or the product in it is provided with a two-dimensional code, bar code or other information code to be scanned by the code scanning module. The unloading module 33 determines whether to take out the product in the carrier according to the product information. The end of the old tool return conveyor line 3 is connected to the head end of the old tool upper conveyor line 31. The old tool upper conveyor line 31 is located above the old tool lower return conveyor line. The end of the old tool lower return conveyor line is provided with an old tool lifting module, which is used to move the carrier from the old tool lower return conveyor line to the old tool upper conveyor line 31. The end of the old tool upper conveyor line 31 is connected to the new tool upper conveyor line 21, and an old tool blocking mechanism 32 is provided at the connection between the old tool upper conveyor line 31 and the new tool upper conveyor line 21. When the product in the carrier is taken out by the unloading module 33, the carrier on the old tool reflux conveyor line 3 is transported to the new tool upper conveyor line 21 through the old tool upper conveyor line 31.

[0075] When the product in the carrier is not taken out by the unloading module 33 , the carrier transport module 34 transports the carrier to the NG product conveying line 35 for delivery.

[0076] The following is the working process of a multi-streamline carrier changing machine described in this embodiment.

[0077] After each workstation on the production line completes processing or testing of the product in the carrier, the production line conveys the carrier to the old tool return conveyor line 3. At this time, the product information recognition module 4 recognizes the carrier on the old tool return conveyor line 3 and obtains product information to find out whether the product in the carrier meets the quality standard. If the product in the carrier meets the quality standard, the unloading module 33 takes out the product in the carrier;

[0078] Afterwards, the carrier on the old tool return conveyor line 3 is transported to the new tool upper conveyor line 21 through the old tool upper conveyor line 31, and the new tool upper conveyor line 21 transports the carrier to the production line, so that the carrier is transported to the production line by the new tool upper conveyor line 21 for recycling. During this period, the new tool blocking mechanism 22 blocks the new tool return conveyor line 2 from supplying new carriers to the new tool upper conveyor line 21; if the production line transports the carrier to the old tool return conveyor line 3, and the product in the carrier does not meet the quality standard, the old tool blocking mechanism 32 blocks the old tool upper conveyor line 31 and transports the old carrier to the new tool upper conveyor line 21, and the carrier handling module 34 transports the carrier to the NG product conveyor line 35 and sends it away, so that another production line can perform post-processing on the products that do not meet the quality standards. During this period, the new tool return conveyor line 2 supplies new carriers to the new tool upper conveyor line 21, and the new tool upper conveyor line 21 transports the carrier to the production line.

[0079] When the new tool upper conveyor line 21 transports the carrier to the production line, the product to be processed or tested can be placed in the carrier in advance. Example

[0080] like Figures 1 to 5 As shown, this embodiment provides a multi-streamline carrier changing machine, which includes a frame 1. The frame 1 is equipped with a new tool return conveyor line 2, a new tool upper conveyor line 21, a loading module 23, a laser engraving machine 24, an old tool return conveyor line 3, an old tool upper conveyor line 31, a product information identification module 4, a unloading module 33, a carrier handling module 34 and an NG product conveyor line 35.

[0081] The upper conveyor line 21 for new tools is located above the return conveyor line 2 for new tools. The end of the return conveyor line 2 for new tools is provided with a new tool lifting module, which is used to transport the carrier from the return conveyor line 2 for new tools to the upper conveyor line 21 for new tools, so that the end of the return conveyor line 2 for new tools is connected to the head end of the upper conveyor line 21 for new tools. The return conveyor line 2 for new tools supplies new carriers to the upper conveyor line 21 for new tools. The end of the return conveyor line 2 for new tools is provided with a new tool blocking mechanism 22, and the end of the upper conveyor line 21 for new tools is connected to the head end of the production line, so that the upper conveyor line 21 for new tools can transport the carrier above it to the production line. The loading module 23 is used to transport the product to the carrier located on the upper conveyor line 21 for new tools.

[0082] The head end of the old tool return conveyor line 3 is connected to the end of the production line so that the production line can convey the products in the carrier to the old tool return conveyor line 3 after processing or testing. The product information identification module 4 is used to identify the carrier on the old tool return conveyor line 3 to obtain product information. The unloading module 33 determines whether to take out the product in the carrier according to the product information. The end of the old tool return conveyor line 3 is connected to the head end of the old tool upper conveyor line 31. The old tool upper conveyor line 31 is located above the old tool lower return conveyor line. The end of the old tool lower return conveyor line is provided with an old tool lifting module, which is used to move the carrier from the old tool lower return conveyor line to the old tool upper conveyor line 31. The end of the old tool upper conveyor line 31 is connected to the new tool upper conveyor line 21, and an old tool blocking mechanism 32 is provided at the connection between the old tool upper conveyor line 31 and the new tool upper conveyor line 21. When the product in the carrier is taken out by the unloading module 33, the carrier on the old tool reflux conveyor line 3 is transported to the new tool upper conveyor line 21 through the old tool upper conveyor line 31.

[0083] When the product in the carrier is not taken out by the unloading module 33 , the carrier transport module 34 transports the carrier to the NG product conveying line 35 for delivery.

[0084] The product information recognition module 4 includes a light spot emitter 41 and a photosensitive element 42. In addition, product information recognition can be applied to each workstation on the production line at the same time.

[0085] The product in the carrier is provided with a product light-transmitting sheet 43 extending outward from the carrier, and the product light-transmitting sheet 43 extends outward to a point where it will not be blocked by the new tool return conveyor line 2, the new tool upper conveyor line 21, the old tool return conveyor line 3, and the old tool upper conveyor line 31. The product light-transmitting sheet 43 can block a portion of light, and the light transmittance of the product light-transmitting sheet 43 is set gradually, and the light transmittance of the product light-transmitting sheets 43 on each product is different, and the gradient range of the product light-transmitting sheets 43 on each product is different, and the gradient range of the product light-transmitting sheets 43 on each product does not overlap; and the laser engraving machine 24 will engrave the product light-transmitting sheet 43 to a specific light transmittance after the product is placed on the carrier.

[0086] The light spot emitter 41 is used to illuminate the light spot 44. At the same time, the light spot emitter 41 illuminates at least two separate light spots 44. The light spot 44 passes through the product light-transmitting sheet 43 and illuminates the photosensitive element 42. When the light spot 44 passes through the product light-transmitting sheet 43, the product light-transmitting sheet 43 blocks a part of the brightness of the light spot 44. The photosensitive element 42 obtains the information of each product and locates each product according to the brightness of the light spot 44. In addition, when the light spot 44 passes through two different heights and the moving product light-transmitting sheet 43, the photosensitive element 42 locates the products at two different heights according to the size and brightness difference between the two separate light spots 44.

[0087] The following is the working process of a multi-streamline carrier changing machine described in this embodiment.

[0088] After each workstation on the production line completes processing or testing of the product in the carrier, the production line conveys the carrier to the old tool return conveyor line 3. At this time, the product information recognition module 4 recognizes the carrier on the old tool return conveyor line 3 and obtains product information to find out whether the product in the carrier meets the quality standard. If the product in the carrier meets the quality standard, the unloading module 33 takes out the product in the carrier;

[0089] Afterwards, the carrier on the old tool return conveyor line 3 is transported to the new tool upper conveyor line 21 through the old tool upper conveyor line 31, and the new tool upper conveyor line 21 transports the carrier to the production line, so that the carrier is transported to the production line by the new tool upper conveyor line 21 for recycling. During this period, the new tool blocking mechanism 22 blocks the new tool return conveyor line 2 from supplying new carriers to the new tool upper conveyor line 21; if the production line transports the carrier to the old tool return conveyor line 3, and the product in the carrier does not meet the quality standard, the old tool blocking mechanism 32 blocks the old tool upper conveyor line 31 and transports the old carrier to the new tool upper conveyor line 21, and the carrier handling module 34 transports the carrier to the NG product conveyor line 35 and sends it away, so that another production line can perform post-processing on the products that do not meet the quality standards. During this period, the new tool return conveyor line 2 supplies new carriers to the new tool upper conveyor line 21, and the new tool upper conveyor line 21 transports the carrier to the production line.

[0090] When the upper conveyor line 21 of the new tool transports the carrier to the production line, the product to be processed or tested can be placed in the carrier in advance. At the same time, the laser engraving machine 24 will engrave the product translucent sheet 43 to a specific transmittance after the product is placed on the carrier. That is, the transmittance of the product translucent sheets 43 on each product on the production line is different, the gradient ranges are different, and the gradient ranges do not overlap, so that each product on the production line can obtain a unique code according to the product translucent sheets 43 with different transmittances.

[0091] When the product information identification module 4 obtains the product information of the product in the carrier, the product drives the product translucent sheet 43 to pass through between the light spot emitter 41 and the photosensitive element 42. At this time, the light spot emitter 41 irradiates the light spot 44 through the product translucent sheet 43 and onto the photosensitive element 42. When the light spot 44 passes through the product translucent sheet 43, the product translucent sheet 43 blocks part of the brightness of the light spot 44. The photosensitive element 42 obtains the information of each product and locates each product according to the brightness changes and brightness values ​​of the light spot 44.
