Description

Technical Field

[0001] This utility model belongs to the field of product thrust detection technology, specifically relating to a product assembly thrust detection system. Background Technology

[0002] In the manufacturing process of consumer electronics, smart home products, and other similar products, product logos are an indispensable component. The secure assembly of product logos (such as brand identification patches and decorative nameplates) directly affects the product's appearance, brand presentation, and user experience. If the logo is not securely assembled, it is prone to detachment or loosening during transportation, use, or subsequent processes. This not only reduces the product's pass rate but may also lead to user complaints and damage the brand's reputation. Therefore, conducting a thrust test on the logo's assembly secureness before the product leaves the factory is a crucial step in ensuring product quality.

[0003] Currently, thrust testing of these product assemblies in the industry is mostly done manually or with semi-automated equipment. In manual testing, operators apply thrust to the assembly using a handheld thrust gauge, judging product quality by observing whether the assembly detaches or reading the thrust count. However, this method is highly subjective, prone to error, and cannot guarantee consistent testing standards. Some companies use semi-automated testing equipment, which uses a mechanical structure to transport products, requiring manual assistance to position the product at the testing station before initiating thrust testing. However, the loading, positioning, and unloading of products using this equipment still require manual intervention, resulting in a high degree of reliance on human labor and low automation. Utility Model Content

[0004] To address the technical problems existing in the prior art, this utility model provides a product assembly thrust detection system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A product assembly thrust detection system, comprising: The product conveying mechanism includes a loading conveyor line and a unloading conveyor line. At least one tray for carrying products is placed on the loading conveyor line, and the loading conveyor line can transport the tray carrying the products to be tested to the pickup position. A thrust detection mechanism is arranged on one side of the product conveying mechanism and is used to perform thrust detection on the product. The picking mechanism is located between the product conveying mechanism and the thrust detection mechanism. The picking mechanism is used to pick up the product to be tested from the tray at the picking position and transfer it to the thrust detection mechanism for thrust testing. The picking mechanism is also used to pick up the qualified product after the thrust detection mechanism has completed the thrust test and put it back into the tray. The unloading conveyor line is used to transport the tray containing the tested products to the unloading position for unloading.

[0006] Furthermore, the thrust detection mechanism includes a first chassis, an electronic control unit disposed in the first chassis, and a plurality of detection components detachably connected to a first platform of the first chassis and electrically connected to the electronic control unit. The detection components include a base plate detachably connected to the first platform and equipped with a barcode scanner, a positioning fixture detachably connected to the upper end of the base plate for fixing the product, a drive module detachably connected to the upper end of the base plate, and detection modules connected to the drive module and distributed above the positioning fixture. The drive module can drive the detection module to reciprocate in a direction closer to or further away from the positioning fixture to achieve contact or separation between the detection module and the product on the positioning fixture; when the detection module moves towards the positioning fixture under the action of the drive module, the working end of the detection module can press against the part of the product to be tested fixed by the positioning fixture, and by applying a preset thrust and collecting force data, the thrust detection of the part of the product to be tested is completed.

[0007] Furthermore, the positioning fixture includes a base plate located above the substrate, a plurality of legs connected between the base plate and the substrate, a support plate disposed on the base plate for supporting the product, and a positioning component capable of fixing the product on the support plate. The support plate is provided with a material detection sensor for detecting whether the product material is in place, and a contour groove with the same shape as the assembly to be tested and the position corresponding to the assembly to be tested is also provided on the support plate. A detachment detection sensor for sensing whether the assembly to be tested has fallen off is installed in the contour groove. The positioning assembly includes several fixed positioning posts arranged at intervals and all located on the outside of the support plate, several first driving units located at the lower end of the base plate, a movable positioning assembly connected to each of the first driving units, and several negative pressure suction cups that pass through the support plate and can adsorb the product. The base plate has an installation notch for installing the movable positioning assembly. The movable positioning assembly includes a side push block connected to the first driving unit and capable of reciprocating along the installation notch, and several movable positioning posts detachably connected to the upper end of the side push block. The movable positioning posts can reciprocate in a direction that approaches or moves away from the support plate. When the product is supported on the support plate, the several movable positioning posts can cooperate with the several fixed positioning posts to surround the product, forming a full circumferential limit on the product.

[0008] Furthermore, the drive module includes a support frame detachably connected to the upper end of the substrate, a lifting mechanism mounted on the support frame and connected to the detection component, and two overshoot limiting members connected to the support frame and spaced apart along the height direction of the support frame. The two overshoot limiting members can be used to prevent the detection component from moving excessively.

[0009] Furthermore, the detection module includes a mounting bracket detachably connected to the drive module, a housing mounted on the mounting bracket, a pressure sensor built into the housing, and a pusher disposed at the lower end of the housing for abutting against the component to be tested on the product. The drive module can drive the mounting bracket to reciprocate in a direction toward or away from the support plate. The pusher can press against the component to be tested on the product fixed by the positioning fixture. An alarm is also installed on the housing for triggering an alarm when the component to be tested on the product falls off.

[0010] Furthermore, the material picking mechanism includes a robotic arm and a second chassis detachably connected to the lower end of the robotic arm and having a second platform; the second platform is provided with an NG material station for bearing products with unqualified thrust, the NG material station includes a support plate detachably connected to the second platform for bearing the material tray, a plurality of limiting posts fixed to each corner of the support plate, a first tray sensor installed on the support plate, and an over-height sensor installed on the limiting posts; the plurality of limiting posts enclose a limiting space for limiting the horizontal displacement of the material tray.

[0011] Furthermore, a visual positioning mechanism is also provided on one side of the second chassis. The visual positioning mechanism includes a fixed frame and a light source and a CCD camera mounted on the fixed frame. The CCD camera and the light source work together to collect real-time posture information of the robotic arm grasping the product and guide the robotic arm to adjust the posture of the product so that the product is accurately placed into the thrust detection mechanism.

[0012] Furthermore, the product conveying mechanism also includes a frame for mounting the loading conveyor line and the unloading conveyor line side by side above it, and a tray transfer mechanism detachably connected to the frame for transferring trays from the loading conveyor line to the unloading conveyor line. The tray transfer mechanism includes a gantry frame connected to the frame, a linear drive mechanism mounted on the gantry frame, and a tray gripping assembly connected to the linear drive mechanism for gripping the trays. The linear drive mechanism can drive the tray gripping assembly to move horizontally reciprocally along the length direction of the gantry frame. The gripping assembly includes a connecting seat connected to the linear drive mechanism, a second drive unit mounted on the connecting seat, a gripping frame connected to the lower end of the second drive unit, and a plurality of gripping suction cups disposed on the gripping frame. The second drive unit can drive the gripping frame to reciprocate in a direction toward or away from the loading / unloading conveyor line, thereby adsorbing and transferring the material tray on the loading conveyor line to the adjacent unloading conveyor line.

[0013] Furthermore, both the loading conveyor line and the unloading conveyor line include an outer frame connected to the frame, two conveyor belts installed inside the outer frame and arranged at intervals, a number of material receiving mechanisms, a material tray fixing mechanism, and a number of stacking and distributing mechanisms located between the two conveyor belts and distributed at intervals. The material-bearing mechanism includes a mounting plate installed at the lower end of the outer frame, a third drive unit connected to the mounting plate, a material-bearing plate connected to the upper end of the third drive unit, and a plurality of material-bearing suction cups distributed on the material-bearing plate. When the material tray is normally conveyed on the conveyor belt, the third drive unit will drive the material-bearing plate to move toward the direction closer to the frame, so that the plane of the material-bearing plate is kept below the conveying surface of the conveyor belt to avoid the conveying path; the third drive unit can also drive the material-bearing plate to move away from the frame, so that the material tray on the material-bearing plate can be separated from the conveying surface of the conveyor belt. The tray fixing mechanism includes a first clamping mechanism distributed at the end of the feeding conveyor line away from the feeding point, and a second clamping mechanism distributed at the end of the unloading conveyor line away from the unloading point. The first clamping mechanism includes two symmetrically arranged clamping members. Each clamping member includes a fourth driving unit connected to the outer frame and a clamping plate connected to the fourth driving unit. The fourth driving unit can drive the two clamping plates to move closer to each other to clamp the tray, and the fourth driving unit can also drive the two clamping plates to move away from each other to release the tray. The second clamping mechanism includes a clamping side plate mounted on the outer frame and a clamping member positioned corresponding to the clamping side plate. The fourth driving unit in this clamping member can drive the clamping plate to reciprocate in the direction of moving closer to or away from the clamping side plate to complete the clamping or releasing of the tray. One of the stacking and distributing mechanisms is located at the material receiving mechanism closest to the first clamping mechanism. This stacking and distributing mechanism can separate several trays stacked on the material receiving plate one by one. After the trays are separated, a single tray can continue to move along a preset conveying path and finally arrive at the location of the first clamping mechanism. Each material receiving mechanism in the unloading conveyor line is equipped with one stacking and distributing mechanism. This stacking and distributing mechanism can stack and store the single trays conveyed from the second clamping mechanism one by one. Each stacking and distributing mechanism includes two stacking and distributing components symmetrically arranged and located on both sides of the receiving plate. Each stacking and distributing component includes a fifth driving unit connected to the outer frame, a connecting plate disposed on the upper end of the fifth driving unit, a sixth driving unit mounted on the connecting plate, and a side base plate connected to the sixth driving unit. During operation, the fifth driving unit can drive the connecting plate to move up and down and back and forth in the vertical direction to adapt to the stacking or distributing of trays of different heights. The sixth driving unit can drive the two side base plates to move closer to each other to complete the distributing of the trays or drive the two side base plates to move away from each other to move away from the trays.

[0014] Furthermore, one side of the material receiving mechanism, the material tray fixing mechanism, and the stacking and distributing mechanism is provided with a material blocking mechanism distributed between the two conveyor belts to block the material tray from moving forward or backward. The material blocking mechanism includes several fixed material blocking components and several movable material blocking components. One of the fixed material blocking components is located at the end of the feeding conveyor line away from the feeding end, and this fixed material blocking component is distributed near the first clamping mechanism; the other fixed material blocking component is located at the unloading end of the unloading conveyor line; the fixed material blocking component includes a first plate connected to the outer frame and a plurality of first material blocking ears disposed on the first plate, the top of the first material blocking ears being higher than the conveying surface of the conveyor belt. The moving material stop assembly includes a second plate connected to the outer frame, a seventh drive unit mounted on the second plate, a connecting base plate connected to the upper end of the seventh drive unit, and a plurality of second material stop ears disposed on the connecting base plate. The seventh drive unit can drive the connecting base plate to move up and down reciprocally, so that the top of the second material stop ears can be higher or lower than the conveying surface.

[0015] In summary, the beneficial effects of this utility model are as follows: 1. Full-process automation, significantly improving testing efficiency and production continuity. The system automates the entire process from "product loading—product picking and attitude adjustment—thrust detection—return of qualified products to trays—tray stacking and unloading," eliminating the need for dedicated personnel to handle repetitive operations such as loading, positioning, sorting, and unloading. This avoids process interruptions caused by low efficiency and fatigue of manual operation, shortens the product testing cycle, and is suitable for batch production scenarios. The interconnected mechanisms, such as the "off-peak temporary storage" function of the material-bearing mechanism, coordinate the loading and tray-sorting rhythms to avoid tray accumulation; the tray-shifting mechanism synchronously transfers empty trays, ensuring "return to tray immediately after testing," eliminating intermediate waiting steps. The continuous assembly line operation seamlessly connects with the front-end production and back-end packaging processes, shortening the overall product production cycle and improving factory capacity utilization. 2. Standardized testing parameters ensure product quality stability and reliability. The thrust testing process utilizes a drive module to achieve uniform and constant pressure control, avoiding issues such as excessive instantaneous force, pressure angle deviation, or force value reading errors that can occur with manual pressure application. This ensures consistent testing conditions (pressure speed, thrust threshold, contact position) for each product, significantly reducing the risk of missed detections and misjudgments due to manual operation. The positioning fixture's full-circumferential mechanical limiting and negative pressure adsorption double fixation ensure no product displacement during testing and consistent testing benchmarks. Thirdly, it reduces production and maintenance costs. The system automatically transfers empty trays from the loading conveyor line to the unloading conveyor line via a tray-shifting mechanism, reusing them as "containers for qualified products." This eliminates the need to purchase new trays and saves on the labor costs of manually handling empty trays. The fully automated process eliminates the need for dedicated personnel to monitor loading, testing, and sorting, while also preventing product scrap due to human error (such as damage from human collisions), reducing the generation of defective products.

Detailed Implementation

[0031] The present invention will be further explained below with reference to specific illustrations.

[0032] Please see Figure 1This utility model provides a product assembly thrust detection system, which can perform thrust detection on logo pieces (i.e., assemblies as described below) pasted or embedded on the surface of various products. The product assembly thrust detection system includes a product conveying mechanism 100, a thrust detection mechanism 400 arranged on one side of the product conveying mechanism 100 for thrust detection of products 300, and a picking mechanism 500 distributed between the product conveying mechanism 100 and the thrust detection mechanism 400. The product conveying mechanism 100 includes a loading conveyor line 110 and a unloading conveyor line 120. At least one tray 200 for carrying products 300 is placed on the loading conveyor line 110, which can transport the tray 200 carrying the product 300 to be tested to the picking position. The picking mechanism 500 is used to transfer the product 300 to be tested from the tray 200 at the picking position to the thrust detection mechanism 400 for thrust detection. The picking mechanism 500 is also used to pick up the qualified products 300 after the thrust testing mechanism 400 completes the thrust test and place them back into the tray 200. The unloading conveyor line 120 is used to transport the tray 200 carrying the tested products 300 to the unloading position for unloading. The thrust testing mechanism 400 ensures that the testing parameters of each product 300 are consistent, avoiding missed inspections or misjudgments due to human error, and improving product quality stability. This system integrates "feeding conveyor - picking - testing - tray return - unloading" into a continuous automated production line operation through the coordinated linkage of various mechanisms, significantly shortening the single-product testing cycle and improving overall testing efficiency. The fully automated process eliminates the need for dedicated personnel to be responsible for feeding, positioning, sorting, etc., eliminating efficiency bottlenecks caused by manual intervention. Compared with manual testing, it is more efficient. The continuous production line operation does not require intermediate stops and can be seamlessly connected with the front-end production and back-end packaging processes, shortening the overall product production cycle.

[0033] In one embodiment, a product assembly thrust detection system further includes a protective net (not shown in the figure) that surrounds the product conveying mechanism 100, the thrust detection mechanism 400, and the material picking mechanism 500. The protective net forms a safety barrier through physical isolation and can also block ejected objects from splashing, preventing secondary injuries to surrounding personnel.

[0034] Please see Figure 2The product conveying mechanism 100 also includes a frame 130 for mounting the loading conveyor line 110 and the unloading conveyor line 120 side-by-side above it, and a transfer mechanism 140 bolted to the frame 130 for transferring the tray 200 on the loading conveyor line 110 to the unloading conveyor line 120. The loading conveyor line 110 and the unloading conveyor line 120 are integrated into a compact side-by-side structure, reducing the floor space occupied by the conveying system and facilitating connection with the thrust detection mechanism 400 and the picking mechanism 500. The transfer mechanism 140 includes a gantry frame 141 connected to the frame 130, a linear drive mechanism 142 mounted on the gantry frame 141, and a tray gripping assembly 143 connected to the linear drive mechanism 142 for gripping the tray 200. The linear drive mechanism 142 can adopt a ball screw transmission mechanism, a gear and rack transmission mechanism, a pneumatic slide (cylinder driven) mechanism, etc. The linear drive mechanism 142 can drive the gripper assembly 143 to move horizontally reciprocally along the length direction of the gantry frame 141. The gripper assembly 143 includes a connecting seat 1431 connected to the linear drive mechanism 142, a second drive unit 1432 mounted on the connecting seat 1431, a gripping frame 1433 connected to the lower end of the second drive unit 1432, and a plurality of gripping suction cups 1434 disposed on the gripping frame 1433. The second drive unit 1432 can be a cylinder. The second drive unit 1432 can drive the gripping frame 1433 to move reciprocally toward or away from the loading conveyor line 110 / unloading conveyor line 120, thereby adsorbing and transferring the material tray 200 on the loading conveyor line 110 to the adjacent unloading conveyor line 120. The second drive unit 1432 drives the gripper 1433 to perform a vertical motion of "descending—adsorption—ascending—transferring—descending—releasing": during descent, it ensures that the gripping suction cup 1434 adheres to the surface of the tray 200; during ascent, it lifts the tray 200 away from the conveyor line to avoid friction damage during transfer. Thus, after the picking mechanism 500 picks up the product 300, the empty tray 200 is transferred from the loading conveyor line 110 to the unloading conveyor line 120 to await and be used to carry qualified products 300 after inspection. Automatic transfer of the empty tray 200 allows it to be directly reused as a "container for qualified products," eliminating the need to purchase new trays 200 or manually handle them.

[0035] Please see Figure 3 , Figure 5 and Figure 6 Both the loading conveyor line 110 and the unloading conveyor line 120 include an outer frame 150 connected to the frame 130, two conveyor belts 160 installed inside the outer frame 150 and arranged at intervals, several material receiving mechanisms 170 arranged between the two conveyor belts 160 and distributed at intervals, a material tray 200 fixing mechanism, and several stacking and distributing mechanisms.

[0036] The material receiving mechanism 170, the material tray 200 fixing mechanism, and the stacking and distributing mechanism are all equipped with blocking mechanisms distributed between the two conveyor belts 160 to prevent the material tray 200 from moving forward or backward. The stacking and distributing mechanism in the feeding conveyor line 110 is located away from the feeding point; that is, on the conveying path, the stacking and distributing mechanism is located in front of the material receiving mechanism 170. Please continue reading. Figure 3The material receiving mechanism 170 includes a mounting plate 171 installed at the lower end of the outer frame 150, a third drive unit 172 connected to the mounting plate 171, a material receiving plate 173 connected to the upper end of the third drive unit 172, and a plurality of material receiving suction cups 174 distributed on the material receiving plate 173. The third drive unit 172 is preferably a cylinder. When the material tray 200 is normally conveyed on the conveyor belt 160, the third drive unit 172 drives the material receiving plate 173 to move towards the direction closer to the frame 130, so that the plane of the material receiving plate 173 is kept below the conveying surface of the conveyor belt 160 to avoid the conveying path. The third drive unit 172 can also drive the material receiving plate 173 to move away from the frame 130, so that the material tray 200 on the material receiving plate 173 can be removed from the conveying surface of the conveyor belt 160. To maximize overall conveying efficiency, during the initial loading stage, workers stack multiple layers of trays 200 carrying products 300. A height limit sensor 151 on the outer frame 150 detects whether the height exceeds the limit. The trays 200 are then piled up and placed at the loading point of the conveyor line 110. This reduces the number of loading operations per cycle, enabling batch transport of trays 200. It is particularly suitable for scenarios with high production volumes and high transport demands, significantly reducing the frequency of manual intervention and improving the overall efficiency of the loading process. Just before the stacked trays 200 reach the conveyor belt 160, the third drive unit 172 of the receiving mechanism 170 is pre-activated, driving the receiving plate 173 to move towards the frame 130. This lowers the plane of the receiving plate 173 below the conveying surface of the conveyor belt 160, creating a clear conveying path for the trays 200 and preventing collisions. This ensures the trays 200 can be smoothly placed on the conveyor belt 160 and make full contact with its conveying surface, preparing for stable subsequent conveying. After the conveyor belt 160 starts, it carries the stacked trays 200 forward along a preset path. A blocking mechanism on one side of the receiving mechanism 170 blocks the trays 200 in their forward direction, preventing them from continuing forward and ensuring they stop precisely above the receiving plate 173, providing accurate positioning for subsequent receiving operations. After the material tray 200 is positioned, the material suction cup 174 on the material support plate 173 is activated, using negative pressure to adhere to the bottom of the material tray 200, enhancing the connection stability between the material tray 200 and the material support plate 173. If the preceding stacking and distributing mechanism is still performing tray distribution operations and cannot receive new material trays temporarily, to prevent the material tray 200 from accumulating on the conveyor belt 160 and causing interruptions in the subsequent feeding process, the third drive unit 172 of the material support mechanism 170 will be activated again, driving the material support plate 173 to rise away from the frame 130 until the material tray 200 is completely detached from the conveyor surface of the conveyor belt 160. At this time, the material tray 200 is in a suspended temporary storage state to achieve staggered waiting of the material tray 200, allowing the material support mechanism 170 to act as a buffer node, coordinating the rhythm of the preceding tray distribution process and the subsequent feeding process, ensuring the smooth flow of the entire conveyor line, and avoiding efficiency losses caused by asynchronous processes.When the forward stacking and distributing mechanism completes the tray distribution operation and is ready to receive a new tray, the third drive unit 172 drives the material support plate 173 to descend, so that the tray 200 re-contacts the conveying surface of the conveyor belt 160, and resumes the forward conveying of the tray 200.

[0037] One of the stacking and distributing mechanisms is located at the nearest material receiving mechanism 170 to the pickup position. This mechanism separates several trays 200 stacked on the material receiving plate 173 one by one. After the trays are separated, each individual tray 200 continues to move along a preset conveying path until it reaches the pickup position. The pickup position is the transfer hub for the trays 200 from the conveying stage to subsequent core processes such as processing and assembly. The corresponding arrangement of the stacking and distributing mechanism with the nearest material receiving mechanism 170 directly minimizes the entire link of the trays 200 from "temporary storage - tray separation - conveying to pickup". When the individual tray 200 moves along the preset path to the pickup position after being separated, the transmission time is greatly shortened due to the extremely short distance.

[0038] Please see Figure 4 Each stacking and distributing mechanism includes two stacking and distributing components 190 symmetrically arranged and located on both sides of the receiving plate 173. Each stacking and distributing component 190 includes a fifth driving unit 191 connected to the outer frame 150, a connecting plate 192 located at the upper end of the fifth driving unit 191, a sixth driving unit 193 mounted on the connecting plate 192, and a side base plate 194 connected to the sixth driving unit 193. The side base plate 194 is provided with a plurality of screwed side lugs 1940, and the side lugs 1940 and the side base plate 194 form an L-shaped receiving position. Both the fifth drive unit 191 and the sixth drive unit 193 preferably employ cylinders. During operation, the fifth drive unit 191 drives the connecting plate 192 to move vertically in a reciprocating motion to accommodate stacking or separating of trays 200 at different heights. The sixth drive unit 193 drives the two side substrates 194 to move closer together to complete the tray separating operation or to move the two side substrates 194 away from each other to move away from the tray 200. Please refer to... Figure 8The side wall of the tray 200 is provided with a side recess 210 that mates with the side lugs 1940. The side recess 210 is recessed from the side wall of the tray 200 toward the interior of the tray 200, and the top of the side recess 210 is a free opening. When the tray is separated by clamping with symmetrically arranged stacking and dispensing assemblies 190, the sixth drive unit 193 mounted on the connecting plate 192 starts to work, driving the side base plates 194 on both sides to move relative to each other in the horizontal direction. Since the side wall of the tray 200 is pre-designed with side recesses 210 that match the side lugs 1940 on the side base plates 194, when the side base plates 194 on both sides move closer to each other under the drive of the sixth drive unit 193, several side lugs 1940 on the side base plates 194 will extend into the side recesses 210 of the bottom tray 200, which is equivalent to an L-shaped receiving position supporting the tray 200. At this point, the side lugs 1940 and the side recesses 210 form a stable engaging structure, effectively separating and positioning the bottom tray 200 from the remaining trays 200 stacked above, preventing tray 200 from shifting or misaligning during the tray separation process. The fifth drive unit 191 drives the side substrate 194 to rise. Since the top of the side recesses 210 of the tray 200 is a free opening, the remaining trays 200 stacked above are also lifted. After rising, the side lugs 1940 are precisely supported on the bottom surface of the second tray 200. At this point, the bottom tray 200 is completely detached from the upper tray stack, realizing the separation operation of a single tray 200. After a single tray 200 is conveyed to the pickup position, the fifth drive unit 191 drives the connecting plate 192 to descend to the initial height, and the sixth drive unit 193 drives the side substrates 194 on both sides to move away from each other. The remaining trays are then placed back on the support plate 173 to continue the next tray separation and peeling operation. The tray distribution operation is automated, requiring no manual intervention throughout the process. It can be seamlessly integrated with the picking equipment in automated production lines, significantly improving the automation level and overall production efficiency of the 200 tray distribution.

[0039] After the trays 200 have been sorted and transported to the pickup position, a tray 200 fixing mechanism is needed to hold each tray 200 in place so that the pickup mechanism 500 can pick up the product 300. The tray fixing mechanism includes a first clamping mechanism located on the feeding conveyor line 110 away from the feeding point, and a second clamping mechanism 180 located on the unloading conveyor line 120 away from the unloading point. The first clamping mechanism includes two symmetrically arranged clamping members 181. Each clamping member 181 includes a fourth drive unit 181A connected to the outer frame 150 and a clamping plate 181B connected to the fourth drive unit 181A. The fourth drive unit 181A is preferably a cylinder. The fourth drive unit 181A can drive the two clamping plates 181B to move closer together to clamp the tray 200, and the fourth drive unit 181A can also drive the two clamping plates 181B to move away from each other to release the tray 200. The first clamping mechanism takes over the conveying results from the stacking and distributing mechanism. After fixing the material tray 200, the picking mechanism 500 can safely pick up the product 300 without worrying about the material tray 200 moving.

[0040] Please see Figure 5 The second clamping mechanism 180 includes a clamping side plate 182 mounted on the outer frame 150 and a clamping member 181 positioned corresponding to the clamping side plate 182. The fourth driving unit 181A in the clamping member 181 can drive the clamping plate 181B to reciprocate in a direction closer to or further away from the clamping side plate 182, thereby clamping or releasing the material tray 200. After material pickup, the first clamping mechanism releases the material tray 200, and the empty tray is transferred to the unloading conveyor line 120 via the tray transfer mechanism 140, where it is fixed by the second clamping mechanism 180. This provides stable positioning for subsequent unloading and storage, preventing the empty tray from sliding arbitrarily on the conveying path and affecting material loading.

[0041] The material blocking mechanism includes several fixed material blocking components 600 and several movable material blocking components 700. One fixed material blocking component 600 is located at the end of the feeding conveyor 110 away from the feeding end, and this fixed material blocking component 600 is distributed near the first clamping mechanism, that is, it blocks the material at the pick-up position to prevent the material tray 200 from "overshooting" and deviating from the pick-up position. Another fixed material blocking component 600 is located at the unloading end of the unloading conveyor 120, and blocks the material at the unloading position to prevent the material tray 200 from rushing out of the unloading conveyor 120 during unloading. Please continue reading. Figure 4 The fixed material stop assembly 600 includes a first plate 610 connected to the outer frame 150 and a plurality of first material stop ears 620 disposed on the first plate 610, the top of the first material stop ears 620 being higher than the conveying surface of the conveyor belt 160.

[0042] Please see Figure 7The movable stop assembly 700 includes a second plate 710 connected to the outer frame 150, a seventh drive unit 720 mounted on the second plate 710, a connecting base plate 730 connected to the upper end of the seventh drive unit 720, and a plurality of second stop supports 740 disposed on the connecting base plate 730. The seventh drive unit 720 is preferably a cylinder, which can drive the connecting base plate 730 to move up and down reciprocally, so that the top of the second stop supports 740 can be higher or lower than the conveying surface. As the dynamic adjustment core of the stop mechanism, the movable stop assembly 700, through the lifting drive of the seventh drive unit 720 and in conjunction with the height change of the second stop supports 740, realizes the on-demand blocking and precise release of the material tray 200.

[0043] After the material tray 200 is fixed in the pickup position, the product 300 is picked up by the pickup mechanism 500 for thrust detection. Please refer to [link / reference]. Figure 1 and Figure 9 The picking mechanism 500 includes a robotic arm 510 and a second housing 520 with a second platform 521, which is bolted to the lower end of the robotic arm 510. A suction mechanism 511 is connected to the end of the robotic arm 510 away from the second platform 521. (See also...) Figure 9 The suction mechanism 511 has suction cups 5110 at both the top and bottom, which can pick up the product 300 from both sides.

[0044] Please continue reading. Figure 9 and Figure 10 A visual positioning mechanism 540 is also provided on one side of the second chassis 520. The visual positioning mechanism 540 includes a fixed frame 541 and a light source and a CCD camera 542 mounted on the fixed frame 541. The CCD camera 542 works with the light source to collect real-time posture information of the robotic arm 510 grasping the product 300 and guides the robotic arm 510 to adjust the posture of the product 300 so that the product 300 is accurately placed into the thrust detection mechanism 400. During the grasping process of the robotic arm 510, the product is prone to posture problems such as displacement and tilting due to factors such as the robotic arm 510's own error, product deformation, and fluctuations in grasping force. The visual positioning mechanism 540 can capture these dynamic deviations in real time and dynamically generate adjustment commands through a closed-loop feedback of "collection-comparison-adjustment" to guide the robotic arm 510 to correct its posture in real time. It can cope with the uncertainties in production without relying on a fixed mechanical structure and avoid the shortcomings of traditional mechanical limiters that "cannot flexibly adapt to dynamic deviations".

[0045] Please continue reading. Figure 9 and Figure 10 The second worktable 521 is equipped with an NG material station 530 for carrying products 300 that do not meet thrust requirements. Please refer to [link / reference]. Figure 11The NG material station 530 includes a support plate 531 bolted to the second table 521 for supporting the material tray 200, several limiting posts 532 fixed to each corner of the support plate 531, a first tray sensor 533 mounted on the support plate 531, and an over-height sensor 534 mounted on the limiting posts 532. The limiting posts 532 enclose a limiting space to restrict the horizontal displacement of the material tray 200. The NG material station 530 serves as a dedicated storage area for non-conforming products 300, clearly separated from the qualified product tray area (material conveyor line 120). This physically eliminates the risk of "mixing qualified and non-conforming products," allowing operators to quickly identify the material trays through station markings without having to check each tray 200 label individually. This reduces misjudgments caused by confusion (such as mistakenly putting non-conforming products 300 into the qualified line) and improves the accuracy of quality control.

[0046] After the robotic arm 510 adjusts the product's posture to 300, it sends it to the thrust detection mechanism 400 for thrust detection. Please refer to [link / reference]. Figure 12 The thrust detection mechanism 400 includes a first housing 410, an electronic control unit disposed within the first housing 410, and several detection components 430 detachably connected to a first platform 420 of the first housing 410 and electrically connected to the electronic control unit. (See also...) Figure 13 and Figure 14The detection assembly 430 includes a base plate 431 screwed to the first platform 420 and equipped with a barcode scanner 4310; a positioning fixture 432 bolted to the upper end of the base plate 431 for fixing the product 300; a drive module 433 bolted to the upper end of the base plate 431; and a detection module 434 connected to the drive module 433 and distributed above the positioning fixture 432. The drive module 433 can drive the detection module 434 to reciprocate in a direction closer to or away from the positioning fixture 432 to achieve contact or separation between the detection module 434 and the product 300 on the positioning fixture 432. When the detection module 434 moves towards the positioning fixture 432 under the action of the drive module 433, the working end of the detection module 434 can press against the part of the product 300 to be tested fixed by the positioning fixture 432. By applying a preset thrust and collecting force data, the thrust detection of the part of the product 300 to be tested is completed. The fixing method of the positioning fixture 432 ensures that each component of the product to be tested maintains a uniform relative position with the working end of the testing module 434, ensuring consistent testing standards and avoiding fluctuations in test data due to standard deviations. The drive module 433 drives the testing module 434 to approach the positioning fixture 432 at a uniform speed along a preset direction (usually vertical). Compared to manual pressure application (which is prone to excessive instantaneous force and uneven pressure application speed), the drive module 433 can precisely control the moving speed and pressure stroke through the electronic control unit, ensuring that the working end of the testing module 434 presses against the component of product 300 at a stable speed, accurately applying a preset thrust (such as 10N, 20N, 50N, etc., settable values). This uniform speed and constant pressure testing method can more realistically simulate the stress scenario of product 300 components in actual use, and the test results are more in line with actual use requirements, avoiding misjudgments of pass or fail due to improper testing methods.

[0047] Please continue reading. Figure 13 and Figure 14The positioning fixture 432 includes a base plate 4321 located above the substrate 431, a plurality of legs 4322 connected between the base plate 4321 and the substrate 431, a support plate 4323 disposed on the base plate 4321 for supporting the product 300, and a positioning component 4324 capable of fixing the product 300 on the support plate 4323. The support plate 4323 is provided with an incoming material detection sensor 4323A for detecting whether the product 300 has arrived in place, and a contour groove 4323B with the same shape as the assembly to be inspected and the position corresponding to the assembly to be inspected is also formed on the support plate 4323, and a detachment detection sensor 4323B0 for sensing whether the assembly to be inspected has fallen off is installed in the contour groove 4323B. The positioning component 4324 includes several fixed positioning posts 43241 spaced apart and all located on the outside of the support plate 4323, several first drive units located at the lower end of the base plate 4321, movable positioning components 43242 connected to each of the first drive units, and several negative pressure suction cups 43243 inserted inside the support plate 4323 and capable of adsorbing the product 300. The base plate 4321 has an installation notch for installing the movable positioning component 43242. The movable positioning component 43242 includes a side push block 43242A connected to the first drive unit and capable of reciprocating along the installation notch, and several movable positioning posts 43242B detachably connected to the upper end of the side push block 43242A. The movable positioning posts 43242B can reciprocate in a direction closer to or further away from the support plate 4323. When the product 300 is supported on the support plate 4323, a number of movable positioning posts 43242B can cooperate with a number of fixed positioning posts 43241 to surround the product 300, forming a full circumferential limit on the product 300.

[0048] Using the above structure, after the robotic arm 510 adjusts the posture of the product 300 and transports it to the support plate 4323 of the positioning fixture 432, the incoming material detection sensor 4323A on the edge of the support plate 4323 first detects the product 300 and immediately sends a "product 300 in position" signal to the electronic control unit. After receiving the signal, the electronic control unit synchronously triggers the positioning component 4324 and the negative pressure system to prepare to start the product 300 fixing process. The first drive unit preferably uses a cylinder. The electronic control unit controls the first drive unit to start, and the drive end pushes the side push block 43242A to move along the mounting notch of the base plate 4321 towards the support plate 4323. The movable positioning column 43242B at the upper end of the side push block 43242A moves synchronously. The movable positioning column 43242B and the fixed positioning column 43241 on the outside of the support plate 4323 together surround the product 300, forming a full-circumferential mechanical limit, restricting the horizontal displacement of the product 300. As the movable positioning column 43242B completes its limiting position, the external negative pressure system is activated, providing negative pressure to the negative pressure suction cup 43243 on the support plate 4323 through an air pipe. The suction cup generates an adsorption force, firmly fixing the product 300 to the surface of the support plate 4323, preventing the product 300 from tilting or shaking in the vertical direction. This dual fixing method ensures that the product 300 remains completely stationary during subsequent thrust testing, guaranteeing a consistent testing benchmark. After the positioning fixture 432 has fixed the product 300, the drive module 433 of the thrust testing mechanism 400 drives the testing module 434 to approach the assembly to be tested on the product 300 and begin applying the preset thrust. During this process: The detachment detection sensor 4323B0 in the contour groove 4323B on the support plate 4323 monitors the status of the assembly in real time. If the assembly falls off under the action of thrust, the sensor immediately sends an "assembly detachment" signal to the electronic control unit. The electronic control unit then determines that product 300 is unqualified, records the detection data, and alarms the staff to remove the detached assembly through the alarm connected to the electronic control unit. If the assembly does not fall off and the force value collected by the detection module 434 reaches the preset qualified range, the detachment detection sensor 4323B0 maintains a normal signal, the electronic control unit determines that product 300 is qualified, and the robotic arm 510 picks up the qualified product 300 and transfers it to the unloading conveyor line 120 for unloading. The NG material with unqualified thrust is picked up by the robotic arm 510 and stored in the NG material station 530.

[0049] The drive module 433 includes a support frame 4331 bolted to the upper end of the base plate 431, a lifting mechanism 4332 mounted on the support frame 4331 and connected to the detection component 430, and two overshoot limiters 4333 connected to the support frame 4331 and spaced apart along the height direction of the support frame 4331. The two overshoot limiters 4333 are used to prevent excessive movement of the detection component 430. The lifting mechanism 4332 can achieve lifting through a servo motor + ball screw lifting mechanism or a stepper motor + synchronous belt lifting mechanism. The drive module 433 can meet diverse detection needs and operate stably for a long time, reducing the risk of downtime due to malfunctions, and providing core support for the efficient and reliable operation of the thrust detection mechanism 400.

[0050] The detection module 434 includes a mounting bracket 4341 bolted to the drive module 433, a housing 4342 mounted on the mounting bracket 4341, a pressure sensor built into the housing 4342, and a pusher head 4343 located at the lower end of the housing 4342 for contacting the assembly to be tested on the product 300. The drive module 433 can drive the mounting bracket 4341 to reciprocate towards or away from the support plate 4323. The pusher head 4343 can press against the assembly to be tested on the product 300 fixed by the positioning fixture 432. The housing 4342 is also equipped with an alarm that triggers an alarm when the assembly to be tested falls off the product 300, and a display screen 4342A for displaying information. The drive module 433 drives the detection module 434 to descend slowly, and the pusher head 4343 gradually contacts the assembly to be tested and applies a pushing force. The pressure sensor is activated simultaneously to collect data and transmits the real-time force value data to the electronic control unit via wires. If an assembly falls off during the thrust test, the electronic control unit immediately determines an anomaly and triggers the alarm on the housing 4342. When the thrust reaches the preset acceptable range and remains stable, the assembly does not fall off, and the pressure sensor value remains stable within the acceptable range, the electronic control unit determines the product is acceptable, sends a "rise reset" signal to the drive module 433, and simultaneously sends a "pick up acceptable product" command to the robotic arm 510, while the alarm remains silent. If the force does not reach the lower acceptable limit but exceeds the upper acceptable limit, the electronic control unit determines "product 300 is unacceptable," triggers the alarm, and sends a "pick up NG product to NG material station 530" command to the robotic arm 510, ensuring that unacceptable product 300 does not flow into the next stage.

[0051] When the product completes inspection and is deemed qualified, the robotic arm 510 picks up the product 300 and places it into the empty tray 200, which is secured by the second gripping mechanism 180. Please continue reading. Figure 5Each material receiving mechanism 170 in the unloading conveyor line 120 is equipped with a corresponding stacking and distributing mechanism, which can stack and store individual trays 200 conveyed from the second clamping mechanism 180 one by one. When the tray 200 moves with the unloading conveyor line 120 to above the receiving plate 173, the sixth drive unit 193 of the stacking and distributing mechanism is activated, driving the two side base plates 194 to move synchronously towards the receiving plate 173. Since the side lugs 1940 and the side base plates 194 form an L-shaped receiving position, during the movement of the side base plates 194, the side lugs 1940 gradually extend under the tray 200, and finally stand on the lower end face of the tray 200 closest to the receiving plate 173. At this time, the horizontal section of the L-shaped receiving position supports the bottom of the tray 200, and the vertical section fits against the side wall of the tray 200, forming a stable support and fixation for the tray 200, preventing the tray 200 from shifting during subsequent lifting and lowering. After the side support lug 1940 receives the tray 200, the fifth drive unit 191 is activated, driving the connecting plate 192 to rise. During the ascent of the connecting plate 192, the side support lug 1940 and the received tray 200 rise synchronously, completely detaching the tray 200 from the surface of the support plate 173. At this point, the support plate 173 returns to an unloaded state, ready to receive the next tray 200 transferred from the second clamping mechanism 180. After the support plate 173 is unloaded, the unloading conveyor line 120 continues to transport the next tray 200 containing qualified products 300 to above the support plate 173. The tray 200 is placed stably on the support plate 173, awaiting stacking. After the new tray 200 arrives, the fifth drive unit 191 of the stacking and distributing mechanism reverses its action, causing the connecting plate 192 and the already supported tray 200 to slowly descend. The bottom of the supported tray 200 is aligned with the top of the new tray 200 to complete the stacking of trays 200. After the upper tray 200 and the new tray 200 are stacked, the sixth drive unit 193 drives the two side substrates 194 to move away from each other, releasing the support constraint on the upper tray 200. Subsequently, the fifth drive unit 191 drives the connecting plate 192 to continue to descend to the initial position, and the side support ears 1940 return to the standby state, waiting for the next new tray 200 to arrive, and repeating the action of "side support ear reception - tray rise - new tray arrival - tray descent and stacking" to realize the layer-by-layer stacking of trays 200.

[0052] The working process of this thrust detection system is as follows: The operator places a multi-layered tray 200 containing the products to be tested (300 units) at the loading point of the feeding conveyor line 110. A height limit sensor 151 detects whether the stacking height is compliant. The conveyor belt 160 of the feeding conveyor line 110 starts, driving the tray 200 along a preset path. The third drive unit 172 of the receiving mechanism 170 pre-drives the receiving plate 173 to descend below the conveyor belt 160, avoiding the conveying path of the tray 200 and ensuring smooth movement of the tray 200. When the tray 200 reaches above the receiving mechanism 170, a blocking mechanism prevents the tray 200 from reaching its precise position, and a suction cup 174 adheres to the bottom of the tray 200 to enhance stability. If the preceding stacking and distributing mechanism is not ready, the receiving plate 173 rises to lift the tray 200 away from the conveyor belt 160 for temporary storage to avoid accumulation. Once the preceding mechanism is ready, the receiving plate 173 descends to return the tray 200 to the conveyor belt 160 and continue to be conveyed to the stacking and distributing mechanism. The sixth drive unit 193 of the stacking and distributing mechanism drives the two side base plates 194 to move closer together, and the side lugs 1940 extend into the side recesses 210 of the bottom tray 200. The fifth drive unit 191 drives the side base plates 194 to rise, separating the bottom tray 200 from the upper tray stack. The single tray is conveyed to the pickup position by the conveyor belt 160. At this time, the first clamping mechanism drives the clamping plate 181B to move closer and fix the tray 200, and the blocking mechanism (fixed blocking assembly 600) prevents the tray 200 from overshooting, thus preparing the pickup mechanism 500.

[0053] The robotic arm 510 of the picking mechanism 500 moves to the picking position and picks up the product 300 to be tested from the tray 200. After picking up, the first clamping mechanism releases the tray 200, and the tray-moving mechanism 140's gripping assembly 143 transfers the empty tray 200 from the loading conveyor line 110 to the unloading conveyor line 120 through a "descending-adsorption-rising-transfer-release" action, where it is fixed by the second clamping mechanism 180, waiting to receive the qualified product 300. The robotic arm 510 carries the product 300 to be tested to the vision positioning mechanism 540, where the CCD camera 542 collects real-time posture data of the product 300 (such as offset and tilt) and compares it with the standard posture to calculate the deviation. The electronic control unit generates adjustment commands to guide the robotic arm 510 to correct the posture of the product 300, ensuring that the product 300 can be accurately placed into the positioning fixture 432 of the thrust detection mechanism 400.

[0054] The robotic arm 510 places the product 300, after adjusting its posture, onto the support plate 4323 of the positioning fixture 432. The incoming material detection sensor 4323A sends a "product in place" signal, and the electronic control unit simultaneously triggers the positioning component 4324 and the negative pressure system: the first drive unit drives the moving positioning column 43242B to move closer, forming a full-circumferential limit with the fixed positioning column 43241; the negative pressure suction cup 43243 activates to adsorb the product 300, providing double fixation to prevent displacement during detection. The drive module 433 of the thrust detection mechanism 400 drives the detection module 434 to descend, and the push head 4343 presses down on the product 300 to be inspected assembly. The pressure sensor collects force data in real time and displays it on the display screen 4342A. If an assembly falls off, an alarm is triggered, reminding the worker to remove the assembly from the contour groove 4323B; for NG materials where the thrust test fails but the assembly has not fallen off, the robotic arm 510 transfers product 300 to the NG material station 530; for qualified product 300 where the force value is within the acceptable range and the assembly has not fallen off, the testing module 434 rises and resets, and the robotic arm 510 prepares to pick up the qualified product.

[0055] The robotic arm 510 picks up a qualified product 300, moves it to the unloading conveyor line 120, and places the product 300 into an empty tray 200 fixed by the second clamping mechanism 180. After unloading, the second clamping mechanism 180 releases the tray 200, and the conveyor belt 160 transports the tray 200 carrying the qualified product 300 to the corresponding receiving plate 173 of the stacking and distributing mechanism. The sixth drive unit 193 of the stacking and distributing mechanism drives the side support ear 1940 to extend under the tray 200, and the L-shaped receiving position supports the tray 200. The fifth drive unit 191 drives the tray 200 to rise and detach from the receiving plate 173, and the empty receiving plate 173 receives the next tray 200. After the new tray 200 is in place, the fifth drive unit 191 drives the upper tray 200 to descend and stack, the side support ear 1940 resets, and the action is repeated to achieve layer-by-layer stacking. When the trays 200 are stacked to a preset quantity, they are conveyed to the unloading point for unloading.

[0056] This thrust testing system offers the following advantages: 1. Full-process automation, significantly improving testing efficiency and production continuity. The system automates the entire process from "product loading—product picking and attitude adjustment—thrust testing—return of qualified products to trays—tray stacking and unloading," eliminating the need for dedicated personnel to handle repetitive operations such as loading, positioning, sorting, and unloading. This avoids process interruptions caused by low efficiency and fatigue of manual operation, shortens the product testing cycle, and is suitable for mass production scenarios. Interlocking mechanisms, such as the "off-peak storage" function of the material receiving mechanism 170, coordinates the loading and tray distribution rhythm, preventing tray 200 from piling up; the tray transferring mechanism 140 synchronously transfers empty trays 200, ensuring "return to tray immediately after testing," eliminating intermediate waiting periods. The seamless assembly line operation can be smoothly integrated with the front-end production and back-end packaging processes, shortening the overall product production cycle and improving factory capacity utilization. 2. Standardized testing parameters ensure product quality stability and reliability. The thrust detection process utilizes the drive module 433 to achieve uniform and constant pressure control, avoiding issues such as excessive instantaneous force, pressure angle deviation, or force value reading errors that occur during manual pressure application. This ensures consistent testing conditions (pressure speed, thrust threshold, and contact position) for each product 300, significantly reducing the risk of missed detections and misjudgments due to manual operation. The positioning fixture 432 employs a combination of circumferential mechanical limiting and negative pressure adsorption for dual fixation, ensuring no displacement of the product 300 during testing and maintaining consistent testing standards. Thirdly, the system reduces production and maintenance costs. The system automatically transfers empty material trays 200 from the loading conveyor line 110 to the unloading conveyor line 120 via the tray transfer mechanism 140, reusing them as "containers for qualified products." This eliminates the need to purchase new material trays 200 and saves on the labor costs of manually handling empty material trays 200. The fully automated process eliminates the need for dedicated personnel to oversee loading, testing, and sorting, while also preventing product 300 scrap due to human error (such as damage from human collisions), reducing the generation of defective products.
