Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the invention. However, it will be understood by those skilled in the art that the following description illustrates preferred embodiments of the invention by way of example only and that the invention may be practiced without one or more of these details. Furthermore, some technical features that are known in the art have not been described in detail in order to avoid obscuring the invention.

Embodiments of the present invention provide a spotting apparatus. The spotting device can perform feeding, spotting, discharging and other operations on the spotted piece (such as a circuit board). The spotting device according to an embodiment of the present invention will be described in detail below with reference to the specific drawings.

As shown in fig. 1-2, the spotting apparatus may include a loading device 1000, a transfer device (not shown), a lifting device (not shown), a spotting device 2000, and a discharging device 3000.

The loading device 1000 may be used to transfer a piece to be printed (i.e. a piece to be printed that is not printed) from a loading position to a loading interface position. Illustratively, the loading device 1000 includes, but is not limited to, a robotic arm or a conveyor belt.

The conveying device can be used for conveying the to-be-spotted piece positioned at the feeding and handover position to the appointed position. And, the conveying device can be used for conveying the spotted piece at the designated position to the blanking handing-over position. Illustratively, the conveyor includes, but is not limited to, a robotic arm or a conveyor belt.

The lifting device can be used for lifting the piece to be printed at the designated position to the printing position. And, the jacking device may be used to transport the spotted member at the spot location (i.e., the spotted member) to the designated location. Illustratively, the jacking devices include, but are not limited to, motor jacking devices or cylinder jacking devices. In some embodiments, the conveyor may comprise two parallel conveyor belts. The jacking device may include a jacking drive and a jacking plate. The jacking plate may be arranged between two parallel conveyor belts. When the sample application member is conveyed to a designated position by two parallel conveyor belts, the lifting driving member can drive the lifting plate to lift. In this process, the lifting plate can lift the piece to be spotted on two parallel conveyor belts to the spot location. Conversely, the lifting driving piece can drive the lifting plate to descend. In this process, the lift plate may lower the spotted piece to a designated position. In this way the spotted pieces are replaced on two parallel conveyors. Two parallel conveyors can continue to transport the spotted pieces to the blanking interface.

The printing device 2000 may be used for printing a printing process on a piece to be printed in a printing position. In this way, the article to be spotted can be made to form a spotted article. The spotting liquid spotted by the spotting device 2000 may be, for example, a glue solution, a pharmaceutical solution, or any other suitable spotting liquid. Thus, the spotting device 2000 may also comprise a glue dispensing device. The spotting device may also comprise a dispensing device.

The blanking device 3000 may be used to transport the spotted pieces from the blanking interface location to the blanking location. Illustratively, the blanking device 3000 includes, but is not limited to, a robotic arm or a conveyor belt. The structures of the discharging device 3000 and the feeding device 1000 may be the same or different.

In practical application, the relevant personnel can place the sample to be spotted piece in the material loading position. Then, the loading device 1000 may transfer the to-be-spotted member from the loading position to the loading handover position. Then, the conveying device can convey the to-be-spotted piece at the feeding and handover position to the appointed position. Then, the jacking device can jack the piece to be spotted at the designated position to the spotting position. By the arrangement, the jacking device can ensure that the sample to be spotted at the spotting position can be in a horizontal state. In this way, the accuracy of the spotting can be improved. The printing device 2000 may then perform a printing operation on the item to be printed in the printing position. In this way, the to-be-spotted piece may become a spotted piece. The jacking means may then be used to transport the spotted piece at the spot location to the designated location. The transfer device may then transfer the spotted piece at the designated location to the blanking delivery location. The blanking device 3000 may then transfer the spotted pieces from the blanking interface location to the blanking location. The person concerned can then take away the spotted sample piece in the blanking position. In this way, the spotting device can complete a single pass. In conclusion, the functions of the sample application equipment are rich, and the automation level is high. The spotting device can improve the work efficiency of spotting, thereby improving the flux of spotting. In addition, the spotting device can be free of participation of personnel, so that labor cost can be reduced. Based on this, the problem of reduced spotting accuracy due to manual operating errors can be avoided, and thus the spotting device also has the advantage of high accuracy.

For example, the printing device may print only one printed item in a single pass. That is, the loading device 1000, the transfer device, the lifting device, the spotting device 2000 and the discharging device 3000 process only one spotted piece at a time. Illustratively, the spotting device may spot a plurality of spotted items in a single pass. That is, the loading device 1000, the transfer device, the lifting device, the spotting device 2000, and the discharging device 3000 can process a plurality of spotted pieces at a time. In some embodiments, the spotting device can spot 18 spotted pieces in one pass. The 18 sample pieces can be arranged in a 3×6 array. The jacking device can jack a plurality of pieces to be spotted at the designated positions to the spotting positions. The deposition device 2000 may simultaneously perform a deposition process on a plurality of members to be deposited at a deposition location. So arranged, the throughput of the spotting device is high.

Illustratively, the spotting device may further comprise a frame 6000. The transfer device, the lifting device and the spotting device 2000 may be arranged in the frame 6000. A relatively closed space can be formed in the frame 6000, so that the conveying device, the jacking device and the spotting device 2000 can be protected, and the spotting process is prevented from being influenced by external environments. The frame 6000 may have two openings. An opening may be used for the transfer of the sample to be spotted in the loading interface position between the loading apparatus 1000 and the transfer apparatus. Another opening may be used to interface the transfer device with the blanking device 3000 for the spotted sample in the blanking interface position.

Illustratively, the spotting device may also include a humidifier (not shown). The humidifier may be disposed within the frame 6000. The humidifier can keep certain humidity in the frame 6000, so that a better environment can be provided for sample application, and the sample application effect is improved.

Illustratively, the loading device 1000 may be pivotally connected to the frame 6000 between a loading open position and a loading engaged position. Specifically, when the feeding device 1000 is in the feeding open position, it may be in a horizontal state. In this way, the loading device 1000 can be used to transport the item to be spotted. When the feeding device 1000 does not need feeding, the feeding device 1000 may be at a feeding attaching position. At this time, the feeding device 1000 may be in a vertical state and may be attached to the side wall of the frame 6000. Thus, the spotting device occupies less space.

Illustratively, the blanking apparatus 3000 may be pivotally connected to the frame 6000 between a blanking open position and a blanking conforming position. Specifically, when the discharging device 3000 is in the discharging open position, it may be in a horizontal state. In this manner, the blanking device 3000 can be used to transport the spotted pieces. When the blanking device 3000 does not need blanking, the blanking device 3000 may be in a blanking attaching position. At this time, the discharging device 3000 may be in a vertical state, and may be attached to a side wall of the frame 6000. Thus, the spotting device occupies less space.

Illustratively, the spotting device may further comprise a visual positioning member and a controller. The visual positioning member can be used for photographing the member to be spotted at a specified position and generating a position signal. Visual positioners include, but are not limited to, cameras. The controller may control the spotting device 2000 to align the sample to be spotted at a specified position based on the position signal. The controller can be built by adopting electronic elements such as a timer, a comparator, a register, a digital logic circuit and the like, or can be realized by adopting processor chips such as a singlechip, a microprocessor, a Programmable Logic Controller (PLC), a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), a Programmable Logic Array (PLA), an Application Specific Integrated Circuit (ASIC) and the like and peripheral circuits thereof. By this arrangement, a high accuracy of the spotting by the spotting device 2000 can be ensured.

The visual positioning assembly may also be used for taking a picture of the printed parts in the printing position after the printing operation and generating the detection signal, for example. The spotting device may also include an alarm. The controller can control the alarm to send out a reminding signal when the spotted piece has the spotting defect based on the detection signal. The manner in which the alarm emits the alert signal includes, but is not limited to, sound or light. Such spotting defects include, but are not limited to, leaks, bias, or mucus. So configured, after the blanking device 3000 transfers the spotted pieces from the blanking transfer position to the blanking position, the personnel can sort out the spotted pieces having the spotting defects for subsequent processing.

For example, as shown in fig. 3-5, the deposition device 2000 may comprise a deposition tool 2100. The deposition tool 2100 can include a tool body 2110, a deposition needle assembly 2120, and a deposition spring 2130.

The jig body 2110 may be used for connection to other components. As is known in the art, the tool body 2110 can be driven by a driving member such as a robot arm, so as to be movable to the spotted member.

The sample needle assembly 2120 may protrude from the jig main body 2110. In the embodiment shown in the figures, the print needle assembly 2120 can protrude downward from the jig body 2110. The print needle assembly 2120 can be used for applying a print process to a piece to be printed in a print position. Specifically, the print needle assembly 2120 can aspirate the print fluid and then spit the print fluid to a desired location on the sample to be printed. The number of print needle assemblies 2120 can be any number including, but not limited to, one, two, or more. In some embodiments, the print needle assembly 2120 can include 48. The 48 print needle assemblies 2120 can be arranged according to the requirements of the printed article. The print needle assembly 2120 can include a dispensing needle assembly. The spotting jig 2100 may also include a dispensing jig.

The spotting elastic member 2130 may be connected between the jig main body 2110 and the spotting needle assembly 2120. The spotting elastic member 2130 may apply an elastic force to the spot needle assembly 2120 to move toward the outside of the jig main body 2110. The spotting elastic member 2130 includes, but is not limited to, a spring or a member made of an elastic material such as rubber.

In practical applications, the print tool 2100 will abut against the workpiece when it moves to a position where the workpiece is to be printed, resulting in a large distance of movement of the print needle assembly 2120. Since the deposition elastic member 2130 is connected between the tool body 2110 and the deposition needle assembly 2120, the deposition needle assembly 2120 can move toward the inside of the tool body 2110 under the pressing of the deposition sample, thereby compensating for the greater distance the deposition needle assembly 2120 moves. Therefore, the print needle assembly 2120 can make elastic contact with the print-to-be-printed member, and thus damage to both due to excessive pressing force can be avoided. Also, in this process, the spotting elastic member 2130 may be compressed. When the printing is completed and the printing needle assembly 2120 is separated from the printed material, the printing elastic member 2130 may release elastic potential energy, so that an elastic force moving toward the outside of the jig main body 2110 may be applied to the printing needle assembly 2120, and thus the printing needle assembly 2120 may be moved to an initial position for the next printing. In summary, the deposition tool 2100 has a low requirement for movement accuracy, which can save costs.

Illustratively, each print needle assembly 2120 can include a print needle 2121 and a sleeve 2122. The needle 2121 and cannula 2122 may be attached by any suitable means, such as welding, clamping or adhesive. The spotting elastic member 2130 may be connected between the jig body 2110 and the sleeve 2122. The sample needle 2121 may protrude from the jig main body 2110. The needle 2121 can be used to aspirate the sample fluid and then spit the fluid to the desired location on the sample being spotted. Print needle 2121 includes, but is not limited to, a glue needle. The cannula 2122 may be sleeved over the sample needle 2121. So configured, the sample needle 2121 and the cannula 2122 can be connected by an interference fit, thereby simplifying the connection structure. The sample application elastic member 2130 may be sleeved on the sample application needle 2121. So arranged, the needle 2121 can provide a better guide for the sample elastic member 2130, thereby preventing the sample elastic member 2130 from moving out of the desired position.

Illustratively, the print needle assembly 2120 can include multiple sets, e.g., two sets, three sets, or more. Each of the plurality of sets may include at least one print needle assembly 2120. Each of the plurality of sets may be connected to one of the spotting fluid drivers, respectively. In particular, one end of the print needle assembly 2120 can be connected to a print fluid drive. The other end of the print needle assembly 2120 can be used for printing. The spotting fluid drive can draw the spotting fluid through its corresponding set of spotting needle assemblies 2120 and spit the spotting fluid to the desired location on the sample to be spotted. The spotting fluid driver includes, but is not limited to, a pump. By this arrangement, the number of printing liquid driving members can be reduced, and thus the cost can be reduced.

Illustratively, the deposition device 2000 can also include a deposition body 2200, a first connector 2300, and a fastener (not shown due to an angle issue).

Sample application body 2200 can be used for attachment to other components. In some embodiments, deposition body 2200 can be used to couple to a drive such as the robotic arm described above. The driving member can drive the deposition body 2200 so that the deposition tool 2100 can be moved to the deposition member.

The first link 2300 is movable between a print clamping station and a print release station. The first connector 2300 of the deposition clamping station is closer to the deposition tool 2100 than the deposition release station. Similarly, the first connector 2300 of the deposition release station is further away from the deposition tool 2100 than the deposition clamping station. As such, when the first connector 2300 is in the deposition clamping station, it can clamp the deposition tool 2100 with the deposition body 2200. The first connector 2300 can release the deposition tool 2100 when in the deposition release station.

The first connector 2300 may be provided with one of a first catch 2310 and a first protrusion 2111. The deposition tool 2100 may be provided with the other one of the first card slot 2310 and the first protrusion 2111. In the embodiment shown in the figures, a first clamping groove 2310 may be provided on the first connector 2300 and a first protrusion 2111 may be provided on the deposition jig 2100. The first protrusions 2111 and the first card slots 2310 may have structures adapted to each other. The first protrusions 2111 can be inserted into the first card slots 2310 when the first connector 2300 is in the sample application gripping station. The first connector 2300 may be inserted into the first catch 2310 while the first connector 2300 is in the print-release position, or may be separated from the first catch 2310.

With the first connector 2300 in the deposition clamping station, a fastener can be secured between the deposition body 2200 and the first connector 2300. Fasteners include, but are not limited to, screws, bolts, or magnets.

In practical use, deposition device 2000 may have a fastener secured between deposition body 2200 and first connector 2300. In this way, the first connector 2300 may be held in the sample application clamping station. The first connector 2300 may clamp the deposition jig 2100 with the deposition body 2200, so that the deposition jig 2100 may be fixed. Further, the first protrusions 2111 are inserted into the first grooves 2310, so that the spot jig 2100 can be positioned. When it is desired to replace the deposition tool 2100, the fastener can be adjusted (e.g., unscrewed) so that the deposition body 2200 and the first connector 2300 can be moved relative to each other. First link 2300 may then be moved to a spot-like release station. In this way, a new deposition tool 2100 may be removed and replaced. When a new deposition tool 2100 is replaced, the first connector 2300 can be moved to the deposition clamping station and the first protrusion 2111 can be inserted into the first card slot 2310. The fastener can then be adjusted (e.g., tightened) so that the fastener can be secured between deposition body 2200 and first connector 2300. In this way, the replacement of the deposition tool 2100 is completed.

In summary, the process of replacing the deposition tool 2100 is simple, so that the deposition device 2000 can reduce the man-hour and improve the working efficiency of replacing the deposition tool 2100. Further, the first protrusions 2111 are inserted into the first grooves 2310, so that the spotting jig 2100 can be positioned at a desired position. And, by fixing the fastening member between the deposition body 2200 and the first connector 2300, it can be ensured that the first connector 2300 is held at the deposition clamping station, thereby ensuring that the structure of the first connector 2300 and the deposition body 2200 clamping the deposition jig 2100 is stable. In this way, the deposition device 2000 can make the deposition accuracy of the deposition jig 2100 mounted thereon high.

Illustratively, the deposition body 2200 may also be provided with deposition fixing holes (not shown due to the angle issue). With the first connector 2300 in the spot clamping station, a fastener may pass through the first connector 2300 and be secured to the spot mounting hole. Illustratively, the first connector 2300 may be provided with a first through-hole 2320. The fastener may pass through the first through hole 2320 and be fixed to the spotting fixing hole. It will be appreciated that the configuration of the spot mounting wells may be adapted to the fastener. For example, when the fastener is a screw, the spotting fixation hole may be a threaded hole. In this way, the structural strength of the fastener fixed between the deposition body 2200 and the first connector 2300 is high.

Illustratively, the first connector 2300 may also be provided with a guide hole 2330. The deposition body 2200 may further be provided with a deposition guide bar 2210. The spotting guide rod 2210 may be inserted into the guide hole 2330. The guide holes 2330 can slide along the deposition guide bar 2210 during movement of the first link 2300 between the deposition clamping station and the deposition release station. So configured, the spotting guide bar 2210 can act as a guide, thereby preventing the first link 2300 from being out of the intended movement track.

Illustratively, the number of guide holes 2330 may be two. The number of spotting guide 2210 may be two. The spotting guide rods 2210 may be inserted into the two guide holes 2330 in a one-to-one correspondence. The spotting guide 2210 may be located on either side of the fastener. In this way, the guiding of the spot guiding rod 2210 works better.

Illustratively, a first card slot 2310 may be provided on the first connector 2300. Also, the first card slot 2310 may penetrate the first connector 2300 along the extending direction thereof. So configured, the deposition tool 2100 can be removed and installed from either side of the first connector 2300 in the direction of extension described above, and is relatively easy to handle. In addition, the first clamping groove 2310 can be conveniently processed, and the spotting device 2000 can be processed and manufactured cheaply.

Illustratively, the first card slot 2310 may have a first sidewall 2311 and a second sidewall 2312. The first and second sidewalls 2311 and 2312 may be oppositely disposed. An opening 2314 may be formed between the first and second sidewalls 2311 and 2312. Illustratively, the first and second sidewalls 2311 and 2312 may be connected to each other, so that a V-shaped first card slot 2310 may be formed. In the embodiment shown in the figures, the first card slot 2310 may also have a bottom wall 2313. The bottom wall 2313 may be connected between the first and second side walls 2311 and 2312. The bottom wall 2313 may be disposed opposite the opening 2314. The angle between the first sidewall 2311 and the second sidewall 2312 may be an acute angle. The acute angle includes, but is not limited to, 30 degrees, 40 degrees, or 45 degrees. The first protrusions 2111 may be gradually inserted into the first card slots 2310 during the movement of the first link 2300 from the deposition release station to the deposition clamping station. Since the angle between the first side wall 2311 and the second side wall 2312 is acute, the first clamping groove 2310 can gradually clamp the first protrusion 2111. Thus, the first connector 2300 can provide a better limit for different deposition tools 2100. The applicability of the spotting device 2000 is better.

Illustratively, the first side wall 2311 may extend in a horizontal direction in a direction toward the opening 2314 of the first card slot 2310, and the second side wall 2312 may extend obliquely downward. Thus, when the first protrusions 2111 are inserted into the first clamping grooves 2310, the first clamping grooves 2310 can function as supporting the first protrusions 2111, so that the sample application jig 2100 can be prevented from falling down due to accidents.

Illustratively, the sample application body 2200 can include a sample application body base 2220 and a second connector 2230. The sample body base 2220 can be used to connect to other components. Illustratively, the print body base 2220 can be used to connect to a drive such as the robotic arm described above. The second connector 2230 can be fixed to the sample body base 2220 by any suitable means, such as welding or connector connection. The second connector 2230 and the first connector 2300 may be disposed opposite. In particular, the second connector 2230 and the first connector 2300 may be disposed on both sides of the deposition tool 2100. The second connector 2230 may have one of a second clamping groove 2231 and a second protrusion 2112 provided thereon. The deposition tool 2100 may be provided with the other of the second card slot 2231 and the second protrusion 2112. In the embodiment shown in the figures, a second clamping groove 2231 may be provided on the second connector 2230 and a second protrusion 2112 may be provided on the spotting jig 2100. The second protrusions 2112 and the second card slots 2231 may have structures that fit into each other. When the first connector 2300 is in the clamping station, it can clamp the deposition tool 2100 with the second connector 2230. And, the second protrusion 2112 may be inserted into the second card slot 2231. So configured, the second connector 2230 can be used as a reference member that can be used to position the deposition tool 2100. Further, by inserting the second protrusions 2112 into the second card slots 2231, a better positioning effect can be achieved on the spot jig 2100.

For example, the structure of the second card slot 2231 can refer to the structure of the first card slot 2310, which is not described in detail for brevity. Of course, the structure of the second card slot 2231 may be different from that of the first card slot 2310.

For example, as shown in fig. 6-8, the spotting device may also include a tray 4100. The tray 4100 may be used to hold a spotting fluid for spotting, such as a glue solution, a pharmaceutical solution, or any other suitable spotting fluid. Specifically, the tray 4100 may have one or more bins 4110 therein. Each silo 4110 may have multiple levels therein. Each level may be used for holding a spotting fluid, respectively. The spotting device 2000 may aspirate the spotting fluid within the stock level. In particular, the deposition device 2000 can be moved to the tray 4100 to insert the deposition needle 2121 into its corresponding level. The spotting fluid driver may then drive the spotting needle 2121 to aspirate the spotting fluid. The printing device 2000 can then be moved to the piece to be printed in preparation for printing.

Illustratively, the spotting device may further comprise a waste disc 4200. Waste tray 4200 may be used to hold waste, such as waste glue, wash spotting liquid, or any other suitable spotting liquid. After the printing device 2000 finishes printing, it can be moved to the waste plate 4200 if the printing liquid needs to be replaced next time printing. The printing fluid drive can then drive the printing needle 2121 to expel the printing fluid therein. In some embodiments, the printing fluid drive can also inject a cleaning fluid (e.g., water) into the print needle 2121 to drain as much of the printing fluid from the print needle 2121 as possible. The washing liquid and the discharged spotting liquid may be discharged into the waste liquid tray 4200 as well.

For example, as shown in fig. 6-8, the spotting device may further comprise a tray positioning means 5000. The tray positioning device 5000 may include a tray positioning body 5100, a reference member 5200, and a resilient clamping assembly 5300.

The tray positioning body 5100 may serve as a base of the tray positioning device 5000. The tray positioning body 5100 may be used for connection to other components. The tray positioning body 5100 may be used for placing the tray 4100 and the waste tray 4200 thereon.

The datum member 5200 can be provided on the tray positioning body 5100 by any suitable means such as welding, adhesive or a connector connection. The structure of the datum member 5200 can be any number including, but not limited to, a datum block, a datum bar, or a datum bar. In some embodiments, a receiving groove 5110 may be provided on the tray positioning body 5100. The receiving groove 5110 may be used to receive the tray 4100. The sidewall of the receiving groove 5110 may be configured as a reference member 5200.

The number of resilient clamping assemblies 5300 can be the same as the number of datum members 5200. Also, the elastic clamping members 5300 may be provided on the tray positioning body 5100 in one-to-one correspondence with the reference members 5200. The resilient clamp assembly 5300 may have a tray clamping station and a tray release station. Specifically, when the elastic clamping assembly 5300 is in the tray clamping station, it can clamp the tray 4100 together with its corresponding reference 5200. When the elastic clamping assembly 5300 is in the tray release station, the tray 4100 is no longer clamped and can thus be released. The elastic clamping assembly 5300 may be in a tray clamping station in a natural state. The natural state refers to a state in which the elastic clamping assembly 5300 is not subjected to an external force.

In practical application, when the tray 4100 needs to be replaced, the tray positioning device 5000 may first apply an external force to the elastic clamping assembly 5300, so that the elastic clamping assembly 5300 may be switched to the tray releasing station. In this manner, the tray 4100 may be removed from between the base 5200 and the resilient clamp assembly 5300. A new tray 4100 may then be placed between the fiducials 5200 and the resilient clamp assembly 5300. Then, the external force to the elastic clamping assembly 5300 can be removed, and the elastic clamping assembly 5300 can be automatically switched to the tray clamping station under the action of the elastic force, so that the tray 4100 can be clamped with the reference member 5200. Thus, the replacement of the tray 4100 is completed. In summary, the operation of replacing the tray 4100 is very simple and requires no tools. Further, even when the size of the replaced tray 4100 is different from the previous tray 4100 due to the machining accuracy or the like, the elastic clamping unit 5300 can clamp the tray 4100 with the corresponding reference member 5200. Therefore, the tray positioning device 5000 has high applicability. And, since the clamped tray 4100 can abut against the reference member 5200, the tray 4100 is maintained at a desired position even if the tray 4100 is replaced. Thus, the subsequent processes such as liquid suction can be easily performed.

For example, as shown in connection with fig. 9-12, each resilient clamp assembly 5300 can include a clamp base 5310, a tray resilient member 5320, and a clamp member 5330. The clamp base 5310 may be secured to the tray positioning body 5100 by welding, adhesive, or a connector connection, among other suitable means. The tray elastic member 5320 may be clamped between the clamp base 5310 and the clamp member 5330. The tray elastic member 5320 may apply an elastic force to the clamp 5330 toward its corresponding reference member 5200. The tray spring 5320 includes, but is not limited to, a spring or a member made of an elastic material such as rubber. When the elastic clamping assembly 5300 is in the tray clamping station, the clamping member 5330 can clamp the tray 4100 together with its corresponding reference member 5200. The resilient clamp assembly 5300 can be used to release the tray 4100 when in the tray release station. The structure of the clamp 5330 may be any, including but not limited to a clamp plate or clamp block.

In practical application, when the tray 4100 needs to be replaced, the tray positioning device 5000 may first apply an external force to the clamping member 5330, so that the elastic clamping assembly 5300 may be switched to the tray releasing station. During this process, the tray spring 5320 may be compressed. In this way, the tray 4100 can be taken out from between the reference member 5200 and the clamp 5330. Then, a new tray 4100 may be placed between the reference member 5200 and the clamp 5330. Then, the external force to the clamp 5330 may be canceled, the tray elastic member 5320 may release the elastic potential energy, and the clamp 5330 may clamp the tray 4100 with the reference member 5200 under the elastic force. Thus, the elastic clamping assembly 5300 can be automatically switched to the tray clamping station. So set up, the structure of elastic clamping component 5300 is comparatively succinct, low in manufacturing cost.

Illustratively, the clamping base 5310 may be provided with a guide slot 5311. The guide groove 5311 may extend in a movable direction of the clamp 5330. The holder 5330 may be provided with guide protrusions 5331. The guide projection 5331 may be inserted into the guide groove 5311. Also, the guide projection 5331 can slide with respect to the guide groove 5311. So configured, the clamp base 5310 can provide better guidance for the clamp 5330, thereby preventing the clamp 5330 from moving out of the intended path of movement.

Illustratively, the clamp base 5310 may include a fixed portion 5312 and an adjustment portion 5313. The fixing portion 5312 may be fixed to the tray positioning body 5100 by welding, adhesive, or a connector connection, or the like in any suitable manner. The fixing portion 5312 may be provided with a clamping fixing hole 5314. The number of clamp fixation holes 5314 may be any number, including but not limited to one, two, or more. In embodiments in which the clamp-securing apertures 5314 include a plurality of clamp-securing apertures 5314, the plurality of clamp-securing apertures 5314 may be aligned along the movable direction of the clamp 5330. The adjustment portion 5313 may be provided with a kidney-shaped hole 5315. The kidney-shaped aperture 5315 may extend in a movable direction of the clamp 5330. Each resilient clamp assembly 5300 can also include a clamp fastener (not shown). The clamp fastener may pass through the kidney-shaped hole 5315 and connect to the clamp fixing hole 5314. Thus, the fixing portion 5312 and the adjusting portion 5313 can be relatively fixed. Clamping fasteners include, but are not limited to, screws, bolts, or pins. It is understood that the structure of the clamp fixing hole 5314 may be adapted to the clamp fastener. For example, when the clamping fastener is a screw, the clamping fixing hole 5314 may be a threaded hole. The tray elastic member 5320 may be clamped between the adjustment portion 5313 and the clamping member 5330. So configured, by adjusting (e.g., unscrewing) the clamp fastener, the position of the adjusting portion 5313 in the movable direction of the clamp 5330 can be adjusted. When the adjustment is completed, the clamping fastener can be adjusted (e.g., tightened) so that the fixing portion 5312 and the adjusting portion 5313 can be relatively fixed. By adjusting the position of the adjusting portion 5313, the compressible length of the tray elastic member 5320 can be changed, so that the magnitude of the elastic force can be adjusted. In this way, the reference member 5200 and the clamping member 5330 can adjust the clamping force of the tray 4100, so that damage to the tray 4100 due to excessive clamping force can be avoided on the premise of sufficient clamping force.

Illustratively, each resilient clamp assembly 5300 may further include a tray guide 5340. The tray guide bar 5340 is slidably connected to the clamp base 5310. In an embodiment in which the clamp base 5310 includes a fixed portion 5312 and an adjustment portion 5313, the tray guide lever 5340 is slidably connected to the adjustment portion 5313. One end of the tray guide 5340 may be connected to the holder 5330. The tray elastic member 5320 may be sleeved on the tray guide bar 5340. So configured, the clamp base 5310 can provide better guidance for the clamp 5330, thereby preventing the clamp 5330 from moving out of the intended path of movement.

Illustratively, the tray guide 5340 may extend through the clamp base 5310. Specifically, the clamping base 5310 may be provided with a second through hole 5316. The tray guide 5340 may extend through the second through hole 5316. It is appreciated that the configuration of the second through hole 5316 may be adapted to the tray guide 5340. The other end of the tray guide lever 5340 may be provided with a stopper 5350. The stopper 5350 may protrude from the tray guide lever 5340 in a radial direction of the tray guide lever 5340. Thus, the stopper 5350 cannot enter the second through hole 5316. The stop 5350 includes, but is not limited to, a flap or a stop. In the embodiment shown in the figures, a screw may be attached to the other end of the tray guide 5340. The cap of the screw may be configured as a stop 5350. The stopper 5350 can prevent the clamp 5330 from moving out of its intended path when the clamp 5330 moves toward its corresponding reference 5200 under the elastic force of the tray elastic 5320.

Illustratively, the datum 5200 can include a first datum 5201 and a second datum 5202. The resilient clamp assembly 5300 can include a first resilient clamp assembly 5301 and a second resilient clamp assembly 5302. The first elastic clamping assembly 5301 can apply an elastic force to the tray 4100 in the first direction X-X toward the first reference 5201. The second elastic clamping assembly 5302 may apply an elastic force to the tray 4100 in the second direction Y-Y towards the second reference 5202. The first direction X-X and the second direction Y-Y may be different. For example, the first direction X-X and the second direction Y-Y may be perpendicular to each other. So configured, the fiducial 5200 and the resilient clamping assembly 5300 can clamp and position the tray 4100 in two directions, thereby allowing the tray 4100 to be more accurately held in a desired position. In an embodiment in which the tray positioning body 5100 is provided with the receiving groove 5110, the receiving groove 5110 may have adjacent first and second groove walls 5111 and 5112. The first groove wall 5111 and the second groove wall 5112 may be configured as a first reference member 5201 and a second reference member 5202, respectively.
