Description

Technical Field

[0001] The present invention relates to the field of electronic component production equipment, in particular to assembly equipment and packaging equipment. Background Art

[0002] During the packaging process of the pressure sensor, it is usually necessary to install the sensitive element, the upper cover, etc. by bonding. Taking the packaging of the sensitive element as an example, during the packaging process of the sensitive element, the sensitive element needs to be assembled, that is, the sensitive element is placed in the housing of the sensor, and the sensitive element can be fixed in the housing of the sensor by glue injection and bonding.

[0003] Because sensitive components are usually very small and very precise, the amount of glue injected and the area of ​​glue injection need to be strictly controlled during the bonding process to avoid leaving glue in areas that cannot be injected. However, because there is more than one surface in the sensor housing that needs to be injected with glue, if glue is injected at the first place that needs to be injected first, and then moved to the second place that needs to be injected, the viscosity of the glue will cause horizontal drawing when the glue injection head switches to the injection surface and moves. Glue will remain in places in the sensor housing where glue injection is not required, thereby affecting the normal use of the pressure sensor after assembly. Summary of the invention

[0050] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0053] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0054] During the packaging process of the pressure sensor, it is usually necessary to install the sensitive element, the upper cover, etc. by bonding. Taking the packaging of the sensitive element as an example, during the packaging process of the sensitive element, the sensitive element needs to be assembled, that is, the sensitive element is placed in the housing of the sensor, and the sensitive element can be fixed in the housing of the sensor by glue injection and bonding.

[0055] Because sensitive components are usually very small and very precise, the amount of glue injected and the area of ​​glue injection need to be strictly controlled during the bonding process to avoid leaving glue in areas that cannot be injected. However, because there is more than one surface in the sensor housing that needs to be injected with glue, if glue is injected at the first place that needs to be injected first, and then moved to the second place that needs to be injected, the viscosity of the glue will cause horizontal drawing when the glue injection head switches to the injection surface and moves. Glue will remain in places in the sensor housing where glue injection is not required, thereby affecting the normal use of the pressure sensor after assembly.

[0056] The following description will be made by taking the mounting part as a sensitive element as an example.

[0057] In order to solve the above problems, the present invention provides an assembly device 1000. Figures 1 to 11 A specific embodiment of the assembly equipment provided by the present invention.

[0058] See also Figures 1 to 4The assembly equipment 1000 includes a machine base 1, a carrier 2 and a glue injection mechanism 100. The machine base 1 has a first station and a second station. The carrier 2 includes a carrier seat, which is used to carry a workpiece. The carrier 2 can be movably arranged on the machine base 1 so that the carrier seat reaches the first station and the second station in sequence. The glue injection mechanism 100 includes a glue injection head 101, which can be movably arranged on the machine base 1 along the up and down directions to inject glue into the workpiece. There are two glue injection mechanisms 100, and one of the glue injection mechanisms 100 is used to inject glue into the first glue injection surface of the workpiece located at the first station, and the other glue injection mechanism 100 is used to inject glue into the second glue injection surface of the workpiece transported from the first station to the second station to form a workpiece to be assembled.

[0059] In the technical solution provided by the present invention, the packaging equipment includes a base 1 having a first station and a second station, and a movable carrying platform 2 is also arranged on the base 1, and the carrying platform 2 includes a carrying seat. When the carrying platform 2 is movable, the carrying seat can be driven to reach the first station and the second station in sequence. The packaging equipment also includes a glue injection mechanism 100, and the glue injection mechanism 100 includes a glue injection head 101. The glue injection head 101 can be movably arranged on the base 1 along the up and down directions to inject glue into the workpiece. The packaging equipment is provided with two glue injection mechanisms 100, one of which is used to inject glue to the first injection surface of the workpiece located at the first station, and the other is used to inject glue to the first station being transported to the second station. The second glue injection surface of the workpiece at the second station is injected with glue to form a workpiece to be assembled. Two glue injection mechanisms 100 are set up, and the glue injection head 101 moves downward and is lifted up after injecting glue on the first glue injection surface of the workpiece. During the lifting process of the glue injection head 101, the glue is lifted up along the drive of the glue injection head 101, and then the workpiece is transported to the second station, and the other glue injection mechanism 100 injects glue on the second glue injection surface. Similarly, during the lifting process of the glue injection head 101, the glue is lifted up along the drive of the glue injection head 101, thereby completing the glue injection of the two glue injection surfaces, because the lifted glue is only retained in the upper and lower directions and will not be retained in the horizontal direction, so as to solve the problem of horizontal drawing when the glue injection head 101 injects glue on multiple glue injection surfaces of the workpiece to be packaged during the packaging process.

[0060] Furthermore, if the mounting parts (such as sensitive components) are small and very precise, in order to strictly control the amount of glue injected during the bonding process to ensure the firmness of the bonding, please refer to Figure 3 and Figure 4In this embodiment, a weighing detection mechanism is provided on the first station and the second station; each of the glue injection heads 101 can be movably provided on the machine base 1 to have a first working state located at the glue injection station and a second working state located at the weighing detection mechanism. In the first working state, the glue injection head 101 is used to inject glue to the workpiece on the bearing seat, and in the second working state, the glue injection head 101 is used to inject glue to the weighing detection mechanism, so that the weighing detection mechanism detects the glue injection of the glue injection mechanism 100. When the glue injection is carried out for a period of time, the glue injection mechanism 100 performs a random check on the glue injection amount of the glue injection mechanism 100, and the glue injection head 101 switches to the second working state. At this time, the glue injection head 101 injects glue to the weighing detection mechanism, so that the weighing detection mechanism detects the glue injection amount of the glue injection mechanism 100. By setting the weighing detection mechanism, the glue injection amount of the glue injection head 101 is intermittently detected to ensure that the glue injection amount of the glue injection mechanism 100 is within the preset value range, so that the glue injection mechanism 100 can accurately control the glue injection amount.

[0061] Specifically, taking the packaging of sensitive components as an example, the amount of glue injection directly affects the subsequent bonding reliability of the sensitive components. During the bonding process, the sensitive components need to be bonded at multiple points, so there are also multiple glue injection points. Therefore, the amount of glue injection at each point needs to be controlled. If the amount of glue injection is too large, the corresponding bonding surface of the sensitive component will become larger, and the places that cannot be bonded will be covered by bonding, thereby affecting the normal use of the sensitive component. If the amount of glue injection is too small, the sensitive component may not be firmly bonded. Therefore, it is particularly important to control the amount of glue injection. In this embodiment, in order to ensure that the amount of glue injected by the glue injection mechanism 100 in the first working state can always be maintained within a preset range, please refer to 3. In this embodiment, the weighing detection mechanism includes a monitoring control unit and a weighing tray 102 arranged on the base 1. In the second working state, the glue injection head 101 is used to inject glue to the weighing tray 102, and the weighing tray 102 is used to obtain the amount of glue injected by the glue injection mechanism 100 in the second working state. The monitoring control unit is electrically connected to the weighing tray 102 and the glue injection mechanism 100. When the amount of glue injected obtained by the weighing tray 102 is within the preset range, When the glue injection amount obtained by the weighing tray 102 is outside the preset range, the monitoring and control unit controls the glue injection mechanism 100 to switch to the first working state, and performs normal glue injection on the workpiece. When the glue injection amount obtained by the weighing tray 102 is outside the preset range, the monitoring and control unit controls the glue injection mechanism 100 to adjust the glue injection amount, and injects glue into the weighing tray 102 again until the glue injection amount is within the preset range. The glue injection mechanism 100 switches back to the first working state, and performs normal glue injection on the workpiece. In this way, the glue injection mechanism 100 is switched to the second working state at intervals, and the glue injection amount is sampled, so that the glue injection amount can be controlled in time.

[0062] Specifically, since the glue injection mechanism 100 switches between the first working state and the second working state, the glue injection mechanism 100 is in an active state. In order to ensure that the glue injection mechanism 100 can accurately inject glue into the workpiece to be bonded, refer to Figure 4 In the present embodiment, the glue injection mechanism 100 further includes a glue cylinder 103, and the glue cylinder 103 has a containing cavity for containing glue liquid. The glue injection head 101 is located at the lower end of the glue cylinder 103 and is connected to the containing cavity. Due to the large mass of the glue liquid, the glue cylinder 103 is prone to vibrate during the activity, thereby driving the glue injection head 101 to vibrate. In order to prevent the position of the glue injection point from being inaccurate due to the shaking, the glue injection mechanism 100 further includes a limit plate arranged on the machine base 1, and the limit plate is located below the glue cylinder 103. The limit plate is penetrated with a limit groove for the glue injection head 101 to pass through, and the limit plate is used to support and fix the glue cylinder 103, so that the glue cylinder 103 reduces the shaking.

[0063] Furthermore, in order to make the assembly equipment 1000 have better compatibility and match more types of workpieces, please refer to the figure. In this embodiment, a plurality of fixing units are arranged on the support seat, and each of the fixing units is used to carry the workpiece of the corresponding model. When using the assembly equipment 1000, the workpiece to be glued is placed in the fixing unit of the corresponding model to fix it. When it is necessary to change the workpiece to another model, it is placed in another fixing unit accordingly.

[0064] Specifically, the fixing unit can take many forms, and different clamps may be provided to clamp and fix the workpiece. In the present embodiment, a receiving groove with an opening facing upward is provided on the upper side of each fixing unit, and each receiving groove is used to accommodate the workpiece of the corresponding model. This arrangement makes it convenient for the robot to take the workpiece out of the loading tray and directly place it into the receiving groove, and also makes it convenient for the robot to take the workpiece out of the receiving groove without other manual operations, which is more efficient.

[0065] Further, in order to facilitate the detection and comparison of the injection quality of the injection mechanism 100, please refer to Figure 4 In this embodiment, the glue injection mechanism 100 also includes an image acquisition device, which is arranged on the machine base 1 and located above the supporting seat. The image acquisition device is used to acquire the image of the workpiece on the supporting seat, and compare the acquired image with a qualified glue injection workpiece, so as to detect the glue injection quality of the glue injection mechanism 100.

[0066] Specifically, in order to switch the glue injection head 101 between the first working state and the second working state, refer to Figure 3In the present embodiment, the glue injection mechanism 100 further includes a driving component, which is disposed on the machine base 1 and is drivingly connected to the glue injection head 101. The driving component may be in various forms, but in order to ensure the accuracy of the glue injection head 101, the driving component requires higher precision. Specifically, in the present embodiment, the driving component includes a first electric slide 104, a second electric slide 105, and a third electric slide 106. The electric slides are low in cost, small in size, low in energy consumption, use of high-precision straight slider guides, smooth movement, and compact in structure, so that the glue injection mechanism 100 can achieve high-precision displacement control in a limited space. The first electric slide 104 is disposed on the The machine base 1, the first electric slide 104 is drivingly connected to the second electric slide 105 to drive the second electric slide 105 to move in the left and right direction, the second electric slide 105 is drivingly connected to the third electric slide 106 to drive the third electric slide 106 to move in the front and back direction, the third electric slide 106 is drivingly connected to the glue injection head 101 to drive the glue injection head 101 to move in the up and down direction. This arrangement allows the glue injection head 101 to be precisely controlled in the X, Y, and Z directions.

[0067] Furthermore, since the assembly equipment 1000 adopts an automated production line, manual monitoring will not be used all the time during the glue dispensing process. When the glue in the glue cartridge 103 is used up, if it is not replenished in time, the glue injection amount of the workpiece will be affected. In the present embodiment, the glue injection mechanism 100 also includes a monitoring device, which is arranged on the machine base 1 and is spaced apart from the glue injection head 101. The monitoring device is used to monitor the glue output of the glue injection head 101 to monitor the remaining glue in the glue cartridge 103. Of course, the monitoring device can be monitored by image acquisition and photography, by weighing, or by using an optical fiber sensor to monitor the glue output, which is not limited in the present solution.

[0068] Furthermore, after the injection is completed, the next step is to place the sensitive element in the sensor housing. At this time, the sensitive element needs to be accurately placed at the injection location. Because the sensitive element is usually small, delicate and easily damaged, the sensitive element and the sensor housing need to be accurately matched during the assembly process to ensure the quality of the assembly. Figures 5 to 7In this embodiment, the machine base 1 further has a third station, the first station, the second station and the third station are sequentially distributed along the transmission, the third station is provided with a loading device and an assembly mechanism 200, the loading device is used to carry the mounting member, the assembly mechanism 200 is used to assemble the workpiece to be assembled sent to the third station, the assembly mechanism 200 includes a picking portion 201, the picking portion 201 is movably arranged on the machine base 1, so as to have a movable stroke between the bearing seat and the loading device, the picking portion 201 is used to pick up the mounting member on the loading device, and transport the mounting member to the bearing seat, so that the mounting member falls onto the workpiece to be assembled; because the mass of the sensitive element is small, the sensitive element When the part falls into the workpiece to be assembled, the sensitive element falls to the upper side of the glue. The pressure of the glue in the workpiece to be assembled only by the gravity of the sensitive element is not enough, and it cannot ensure that the glue is fully in contact with the sensitive element, which will lead to insufficient bonding strength. In this embodiment, the assembly mechanism 200 also includes a pressing component 202, and the pressing component 202 is movably arranged on the machine base 1 to have a movable stroke close to or away from the bearing seat. The pressing component 202 is used to press the sensitive element on the bearing seat down and fix it to the workpiece to be assembled in the movable stroke close to the bearing seat, so that the sensitive element forms more bonding surfaces with the workpiece to be assembled as much as possible, so that the bonding effect is better.

[0069] Specifically, the picking component 201 can be in various forms, and can be clamped or glued. Considering the precision of the sensitive element, it may be inconvenient to pick up by clamping or other methods, or the sensitive element may be damaged. Please refer to the figure. In this embodiment, the picking component 201 includes a vacuum suction cup, which is used to absorb or release the sensitive element. The sensitive element has a small mass. The sensitive element is sucked by the vacuum suction cup to generate negative pressure, and the adsorption force is easier to control, so that the sensitive element is not easily damaged when picking it up. When the sensitive element needs to be placed, it only needs to stop generating negative pressure, and the sensitive element will fall into the workpiece to be assembled. Such a setting operation is not only simple, but also suitable for the precision characteristics of the sensitive element.

[0070] Furthermore, since both the pressing component 202 and the material picking component 201 need to be processed or moved on the bearing seat, in the present embodiment, the assembly mechanism 200 also includes a rotating arm, which is rotatably arranged on the machine base 1 around a rotating axis, so as to have a first end and a second end that rotate around the rotating axis, the material picking component 201 is arranged at the first end, and the pressing component 202 is arranged at the second end, so that the material picking component 201 and the pressing component 202 are alternately located on the bearing seat, so that one driving device can be fully utilized to simultaneously drive the pressing component 202 and the material picking component 201 to work on the same bearing seat, so that the activity stroke of the device driven by the pressing component 202 and the material picking component 201 when switching to the bearing seat is shorter and more convenient.

[0071] Furthermore, during the pressing process, since the pressing of the sensitive element is controlled by the size of the pressing stroke provided by the driving device, when the stroke is too small, the sensitive element cannot be completely pressed into place, and when the stroke is too large, the sensitive element is subjected to excessive impact force and the glue is completely squeezed out, resulting in a poor gluing effect and the sensitive element may also be damaged. In order to buffer and reduce the pressing force of the pressing component 202 contacting the sensitive element, in this embodiment, the pressing component 202 includes a pin 2021 and a spring 2022, and the pin 2021 is connected to the rotating arm through the spring 2022, so that the spring 2022 will be deformed during the pressing process, so that the pressing force can be partially absorbed by the spring 2022, so that the sensitive element will not be suddenly subjected to excessive pressing force. In this way, the pressing force is adjusted by the spring 2022, so that the product compatibility of the assembly mechanism 200 is stronger, and the precision requirements for the driving device are not too strict.

[0072] Furthermore, since the movable stroke of the sensitive element relative to the workpiece to be assembled is very small when the sensitive element is pressed, the displacement control of the sensitive element needs to be precisely controlled. In this embodiment, the assembly mechanism 200 further includes a pressure sensor 203, a displacement sensor 204 and a driving device arranged on the machine base 1. The driving device is drivingly connected to the pressing component 202. The pressure sensor 203 and the displacement sensor 204 are arranged between the pressing component 202 and the driving device. The pressure sensor 203 is used to detect the pressure signal of the pressing component 202, and the displacement sensor 204 is used to detect the displacement signal of the pressing component 202, so that the driving device drives the pressing component 202 to move up and down according to the pressure signal and the displacement signal. In this way, by setting up dual sensors, the driving device can be precisely moved to drive the ejector pin 2021 to press the sensitive element according to the pressure and displacement range values.

[0073] Furthermore, in order to facilitate the detection and comparison of the assembly quality of the assembly mechanism 200, the assembly mechanism 200 also includes an image acquisition device, which is arranged on the machine base 1 and located above the supporting seat. The image acquisition device is used to acquire images of the sensitive element and the workpiece to be assembled at the supporting seat to detect the assembly quality of the sensitive element and the workpiece to be assembled, and compare the acquired image with a qualified assembly workpiece, thereby detecting the assembly quality of the assembly mechanism 200.

[0074] Furthermore, during the assembly process, since the workpiece to be assembled is placed on a processing table, the processing table transports the workpiece to be assembled from the previous injection station to the assembly station. The sensitive component is manufactured from another production line, so when assembly is required, the sensitive component is placed in a tray and waits to be transported to the support seat. Please refer to Figure 7 In this embodiment, the assembly mechanism 200 further includes a transmission member 210 disposed on the machine base 1, and the transmission member 210 is disposed between the loading device and the supporting seat to transfer the sensitive element in the loading device to the material picking station.

[0075] Specifically, the transmission member 210 can be in various forms. In the present embodiment, the transmission member 210 includes two guide rails 2101, an electric slide 2102 and a material tray. The two guide rails 2101 are arranged at intervals and extend respectively between the loading device and the supporting seat. The material tray is used to carry the sensitive element and is straddled between the two guide rails 2101. The electric slide 2102 is drive-connected to the material tray to drive the material tray to slide along the two guide rails 2101. In order to enable the material tray to be accurately transported to the supporting seat, each guide rail 2101 is provided with a plurality of auxiliary wheels 205 in sequence along the length direction. The material tray is located on the upper side of the plurality of auxiliary wheels 205. In this way, during the sliding process of the material tray, the material tray slides toward the supporting seat along the rotation direction of the auxiliary wheels 205, and the auxiliary wheels 205 play a good guiding and assisting role.

[0076] Furthermore, many industrial plastic surfaces such as PE, PP, ABS, PET, PS, EPDM, PTFE, etc. usually have low surface energy and cannot be fully wetted, making it very difficult to paint, print and bond on them; even some organic materials, metals, silicone rubber, glass ceramics, etc. are often difficult to coat and bond, or require a high price to solve with the help of professional polymer products. In order to increase the surface adhesion of the workpiece, the assembly equipment 1000 can maintain the maximum adhesion after the workpiece is injected and assembled, and the glue is not easy to loosen and fall off. Please refer to Figure 8In this embodiment, the machine base 1 also has a pretreatment station, and the pretreatment station is used to carry the workpiece; the assembly equipment 1000 also includes a plasma activation mechanism 300, and the plasma activation mechanism 300 is located at the pretreatment station; the plasma activation mechanism 300 includes an activation head 301, and the activation head 301 can be movably arranged on the machine base 1 to have a movable stroke close to or away from the workpiece at the pretreatment station. The activation head 301 is used to perform high-temperature activation on the workpiece. Through the activation head 301, plasma generated by different atmospheres can form different active groups, such as oxygen groups such as -OH (hydroxyl functional group) or nitrogen groups such as NH (amino functional group), etc. These active groups can be concentrated on the surface of the material, which makes it very easy to achieve the bonding of two different substances, which is incomparable to traditional surface treatment processes.

[0077] For further information, see Figure 1 and Figure 2 In this embodiment, the carrier platform 2 includes a turntable, and the rotating axis of the turntable is extended in the up and down directions. The pretreatment station, the first station, the second station and the third station are arranged in sequence along the circumference of the turntable, and the turntable is driven to rotate, so that the various mechanisms on the overall assembly equipment 1000 can transport the workpiece from the pretreatment station to the first station, the second station and the third station in sequence through the set turntable. With this arrangement, the structure is compact and the processing efficiency is also high.

[0078] Furthermore, before assembly, multiple workpieces are all stored in the tray in advance. In order to improve the automation and efficiency of packaging production and cooperate with the later process flow, please refer to Figure 1 , Figure 2 and Fig. 9In this embodiment, the base 1 also has a loading station, and the loading station, the first station, the second station and the third station are sequentially distributed along the transmission. The assembly equipment 1000 also includes a circulating loading mechanism 400, and the circulating loading mechanism 400 is arranged adjacent to the base 1 at intervals. The circulating loading mechanism 400 is used to provide the workpiece to the bearing seat on the first station. The circulating loading mechanism 400 includes a frame 3, and the frame 3 is sequentially distributed with a feeding station a, a picking station b, Transfer station c and discharging station d; the circulating feeding mechanism 400 also includes a first transmission member 31, a second transmission member 32 and a third transmission member 33 arranged on the frame 3, the first transmission member 31 is extended between the feeding station a and the picking station b, the second transmission member 32 is extended between the transfer station c and the discharging station d, the third transmission member 33 includes a receiving plate 34, the receiving plate 34 is used to receive the empty material tray, and the receiving plate 34 is movably arranged between the picking station b and the transfer station c. When conveying a tray loaded with multiple workpieces, the first transmission member 31 transports the tray from the feeding station a to the picking station b. At the picking station b, the multiple workpieces are picked up in sequence to form an empty tray. After the receiving plate 34 transports the empty tray formed in the previous process at the picking station b to the transfer station c, the empty tray is transported from the transfer station c to the unloading station d through the first transmission member 31. By setting the receiving plate 34, during the process of taking out the multiple workpieces in the tray in sequence at the picking station b, the receiving plate 34 turns back between the picking station b and the transfer station c, making full use of the time for taking out the multiple workpieces and efficiently transporting the empty tray to the transfer station c.

[0079] Specifically, in the present embodiment, the first transmission member 31 and the second transmission member 32 are arranged side by side, and the transmission directions of the first transmission member 31 and the second transmission member 32 are opposite, and they extend horizontally respectively, so that the feeding station a and the discharging station d are located at one end of the frame 3. When loading or unloading, the operator or the loading robot only needs to be on one side of the frame 3 to conveniently load and unload materials efficiently and in a short stroke. The transfer stroke after loading and unloading at one side of the transfer station c and the discharging station d is also a short active stroke. The setting of the loading mechanism makes the entire conveying stroke more compact and occupies less floor space.

[0080] Furthermore, in the production line, in order to make the circulating feeding mechanism 400 adapt to the height of the carrying platform 2 of the next process and facilitate the material picking at the material picking station b of the circulating feeding mechanism 400, in the present embodiment, the third transmission member 33 is located above the first transmission member 31 and the second transmission member 32, and the height of the third transmission member 33 can be set to be basically consistent with the height of the operating table of the next process. The third transmission member 33 has a first end located at the material picking station b and a second end located at the transfer station c. The circulating feeding mechanism 400 also includes a transfer device, which is arranged on the frame 3, and the transfer device includes a first transmission member 31 and a second transmission member 32. A slide 35 and a second slide 36, the first slide 35 can be movably arranged up and down at the material picking station b, and is used to transport the material tray from the first transmission member 31 upward to the first end of the third transmission member 33, so that the material picking robot in the production line can conveniently reciprocate and pick up materials on basically the same horizontal plane, shortening the material picking stroke, and the second slide 36 can be movably arranged up and down at the transfer station c, and is used to transport the empty material tray from the second end of the third transmission member 33 downward to the second transmission member 32. This arrangement enables the circulating feeding mechanism 400 to also have the shortest stroke in the up and down directions, and the overall structure of the entire circulating feeding mechanism 400 is compact.

[0081] Specifically, when the receiving plate 34 receives the tray or an empty tray, it is located below the tray. Fig.11In this embodiment, the transfer device also includes a first vacuum suction cup and a second vacuum suction cup. The first slide 35 is driven and connected to the first vacuum suction cup, and the first vacuum suction cup is used to absorb or release the material tray. The second slide 36 is driven and connected to the second vacuum suction cup, and the second vacuum suction cup is used to absorb or release the empty material tray. When the material tray needs to be transported from the first transmission member 31 to the material picking station b, the first vacuum suction cup is located above the receiving plate 34. When the receiving plate 34 is opposite to the first vacuum suction cup, the negative pressure generated by the first vacuum suction cup adsorbs the material tray, and then transfers it upward. The manipulator cooperates to pick up the workpieces located at the material picking station b one by one. Take out, and when all are taken out, the first vacuum suction cup stops generating negative pressure, and the empty tray falls to the receiving plate 34, and the receiving plate 34 then transfers the empty tray to the transfer station c, and the second vacuum suction cup is located above the receiving plate 34. When the receiving plate 34 is opposite to the second vacuum suction cup, the second vacuum suction cup generates negative pressure to adsorb the empty tray, and then transmits it downward. When the empty tray is sent to the first transmission member 31, the negative pressure is stopped, and the empty tray falls to the first transmission member 31. Of course, the method of picking up the tray is not limited to the above-mentioned vacuum adsorption method, and other structures that can be clamped and pick up the tray are all within the scope of protection of this application.

[0082] Further, in order to make the tray more stable during the conveying process, please refer to Fig.11 In this embodiment, the transfer device also includes a first connecting plate and a first connecting plate, the first connecting plate is connected to the first slide 35, and a plurality of the first vacuum suction cups are arranged on the first connecting plate at intervals, the first connecting plate is connected to the second slide 36, and a plurality of the first vacuum suction cups are arranged on the first connecting plate at intervals. By setting up a plurality of vacuum suction cups, the transfer device has sufficient adsorption force to adsorb the material tray, which makes the material tray more stable during the transmission process, and also prevents the material tray from falling and being damaged when one of the vacuum suction cups is damaged and does not work during the transmission process.

[0083] For further information, see Fig.11In this embodiment, the circulating feeding mechanism 400 also includes a detection component and a controller arranged on the first connecting plate, the detection component is used to detect the number of the multiple workpieces in the material tray, the controller is electrically connected to the detection component and the multiple first vacuum suction cups, the controller can control the multiple first vacuum suction cups to absorb or release according to the detection quantity of the detection component, when the robot takes the material, the detection component monitors the situation of the material tray in real time, when the multiple workpieces in the material tray are taken, the controller controls the multiple first vacuum suction cups to release the empty material tray, so that the time spent on the material taking process will not be wasted, the degree of automation is improved, and it is efficiently coordinated with the following processing steps.

[0084] Specifically, since the material tray has a larger bearing surface for carrying multiple workpieces, in order to prevent the material tray from shaking during transmission and causing multiple workpieces to fall, in this embodiment, the first transmission member 31 includes two first guide rails and a first driver, and the two first guide rails are arranged at intervals so that the material tray is mounted between the two first guide rails, and each of the first guide rails extends between the feeding station a and the picking station b. The first drive device is used to drive the material tray to move along the two first guide rails. The second transmission member 32 includes two second guide rails and a second driver, and the two second guide rails are arranged at intervals so that the empty material tray is mounted between the two second guide rails, and each of the second guide rails extends between the feeding station a and the picking station b. The second drive device is used to drive the empty material tray to move along the two second guide rails. In this way, by arranging two first guide rails and two second guide rails to lift the material tray on both sides of the bottom, the lifting force on the material tray is more evenly distributed.

[0085] Furthermore, the circulating feeding mechanism 400 also includes a first infrared sensor and a first controller, and a second infrared sensor and a second controller. The first infrared sensor is arranged on any one of the two first guide rails to sense and identify the material tray transported on the first transmission member 31. The first controller is electrically connected to the first infrared sensor and the first driver. The first controller can control the first driver to work according to the sensing detection result of the first infrared sensor. When the material tray is placed at the feeding station a, the first controller controls the first driver to drive the material tray to the material picking station b. Like the first transmission member 31, on the second transmission member 32, the second infrared sensor is arranged on any one of the two second guide rails to sense and identify the empty material tray transported on the second transmission member 32. The second controller is electrically connected to the second infrared sensor and the second driver to control the second driver to work according to the sensing detection result of the second infrared sensor, so that when the empty material tray is transported to the transfer station c, the second controller controls the second driver to drive the empty material tray to the discharging station d.

[0086] Furthermore, in order to facilitate the cyclic loading mechanism 400 to be more compatible and adapt to more processing platforms, in the present embodiment, a steering wheel is provided at the bottom of the frame 3, which can conveniently move the cyclic loading mechanism 400 to each workstation in the production line where loading is required, thereby increasing the versatility of the cyclic loading mechanism 400.
