Description

Technical Field

[0001] The utility model relates to the technical field of testing and sorting, in particular to a transport device and testing and sorting equipment. Background Art

[0002] Since chip products are small in size, large in number, and easy to damage, they need to be placed on trays and stored in silos before and after testing and sorting. By transporting the trays through a tray handling device, the chip products can be transferred in batches between designated workstations. The tray handling device is generally powered by a power source or air source, but it may encounter special working conditions such as power outages or air outages during actual operation. At present, a brake is generally used to deal with the above special working conditions, and the tray handling device can remain in the state of the brake at the moment of the brake. However, the tray handling device will cause large vibrations at the moment the brake stops, which may cause the chip products in the tray to tilt or scatter, thereby affecting the results of the test sorting.

[0033] See also Figure 1 The utility model provides a test sorting device 10 and a handling device 100. The test sorting device 10 includes a handling device 100, a material bin 200, a loading mechanism 300, a unloading mechanism 400, a testing machine 500 and a plurality of loading test trays 600.

[0034] The silo 200 is used to store trays, and the trays are used to hold products to be tested or tested. Specifically, the products held in the trays are chips. Among them, the trays are divided into trays to be tested, empty trays and tested trays. The trays to be tested are trays that hold untested products, the empty trays are trays from which all products have been taken out, and the tested trays are trays that hold tested products. Preferably, the silo 200 is divided into a supply silo 210 and a discharge silo 220. The supply silo 210 is used to store the trays to be tested, and the discharge silo 220 is used to store the tested trays. The supply silo 210 and the discharge silo 220 are spaced apart in the first direction. The supply silo 210 and the discharge silo 220 may also be provided in plurality along the first direction. Specifically, the first direction refers to Figure 1 Left and right directions shown.

[0035] The handling device 100 can transfer the material tray to be tested stored in the material bin 200, specifically the feeding bin 210, to the feeding station, and the loading mechanism 300 can transfer the products in the material tray to be tested at the feeding station to the loading test tray 600 located at the loading station. Multiple loading test trays 600 can circulate between the loading station, the testing station and the unloading station in sequence. When the loading test tray 600 at the loading station is full, the loading test tray 600 will be transferred to the testing station and the products therein will be tested by the testing machine 500. After the test is completed, the loading test tray 600 will be transferred to the unloading station, and the products in the loading test tray 600 will be unloaded by the unloading mechanism 400.

[0036] When the last loading test tray 600 flows out from the loading station, the next loading test tray 600 can flow into the loading station and continue to handle the products in the tray to be tested. When all the products of a tray to be tested are transferred to the loading test tray 600, the tray to be tested becomes an empty tray. The handling device 100 can transfer the empty tray on the feeding station to the receiving station. After the empty tray is transported from the loading station to the receiving station, the handling device 100 can transport a new tray to be tested in the material bin 210 to the loading station.

[0037] The unloading mechanism 400 can transfer the products in the loading test tray 600 transferred to the unloading station to the empty tray on the receiving station. When the empty tray is filled with the tested products and becomes a tested tray, the handling device 100 can also transfer the tested tray on the receiving station to the silo 200. When all the tested products in the loading test tray 600 on the unloading station are transferred out, the loading test tray 600 will be transferred to the loading station again and be ready to receive the untested products.

[0038] In this embodiment, the unloading mechanism 400 includes a first unloading component 410 and a second unloading component 420. The first unloading component 410 first transfers the products in the loading test tray 600 of the unloading station to the transfer station, and the second unloading component 420 then transfers the products from the transfer station to the empty tray on the receiving station. The transfer station can cache the products transferred to the unloading station, thereby ensuring that the loading test tray 600 can be circulated at a set frequency to ensure coordination of various processes.

[0039] It should be noted that multiple empty trays can be placed at the receiving station at the same time to hold different grades of tested products, and the grade of the product is related to the test results of the product at the test station. For example, according to the test results, the products can be divided into three grades: A, B, and C. Then three empty trays are placed at the receiving station at the same time to hold grade A, grade B, and grade C products respectively. In the silo 200, specifically in the unloading silo 220, the tested trays containing products of different grades can be stored separately for easy access.

[0040] Three groups of conveying devices 100 can be set. The first group of conveying devices 100 is used to transfer the material trays to be tested stored in the silo 200 to the feeding station; the second group of conveying devices 100 is used to transfer the empty material trays on the feeding station to the receiving station; the third group of conveying devices 100 is used to transfer the measured material trays on the receiving station to the silo 200.

[0041] By making multiple loading test trays 600 circulate among the loading station, the testing station and the unloading station in sequence, when the loading station is loading untested products by the loading mechanism 300, the testing machine 500 can test the products at the testing station, and the unloading mechanism 400 can unload the tested products at the unloading station. It can be seen that the above-mentioned testing and sorting equipment 10 can realize the simultaneous operation of multiple stations, so it can effectively improve the testing efficiency.

[0042] In addition, in this embodiment, a preheating station is provided between the loading station and the testing station, and a rewarming station is provided between the testing station and the unloading station, and multiple loading test trays 600 can pass through the preheating station and the rewarming station during the circulation process. The loading test tray 600 loaded with untested products first enters the preheating station for preheating and temperature control before entering the testing station for testing, thereby avoiding the need for the product to heat up for a long time after entering the testing station to reach the temperature required for the test. After the loading test tray 600 loaded with tested products is removed from the testing station, it first enters the rewarming station for cooling, and waits until the temperature of the product drops to the set value before flowing to the unloading station, thereby preventing the temperature from dropping sharply and affecting the performance of the product.

[0043] The preheating station, the test station and the temperature return station can all be provided with corresponding temperature control cavities, and the required temperature can be adjusted and maintained in the temperature control cavity. The loaded test tray 600 can enter the corresponding temperature control cavity respectively, so as to realize preheating, test temperature control and temperature return of the product.

[0044] Please also read Figure 2 and Figure 3 The transport device 100 in the preferred embodiment of the present invention includes a transport base 110 , a transport unit 120 , a driving mechanism 130 and a braking mechanism 140 .

[0045] The transport seat 110 plays a supporting role, and the transport device 100 can be installed as a whole through the transport seat 110. The transport unit 120 is installed on the transport seat 110, and is used to carry the material tray. Specifically, the transport unit 120 can obtain the material tray by vacuum adsorption, electromagnetic adsorption, clamping, etc. The transport unit 120 can move relative to the transport seat 110 to perform a transport operation. Among them, the transport operation refers to transporting the acquired material tray from one position to another designated position. Specifically, it can be transferring the material tray to be measured stored in the silo 200 to the feeding station; or transferring the empty material tray on the feeding station to the receiving station; or transferring the measured material tray on the receiving station to the silo 200.

[0046] Driven by the driving mechanism 130, the transport unit 120 can move along a preset trajectory to perform a transport operation. For example, the driving mechanism 130 can drive the transport unit 120 to perform linear motion, circular motion or curvilinear motion to transport the material tray. Specifically in the present embodiment, the transport unit 120 is slidably mounted on the transport seat 110 along a preset direction, and the driving mechanism 130 can drive the transport unit 120 to reciprocate in the preset direction to transport the material tray. The transport unit 120 can be mounted on the transport seat 110 via a guide rail slider assembly (not shown), and the above-mentioned preset direction intersects with the first direction, specifically Figure 1 Up and down directions shown.

[0047] In addition, the transport device 100 can also be installed on the moving end of the translation mechanism (not shown) through the transport seat 110. The translation mechanism can drive the transport device 100 to move back and forth in the first direction to expand the coverage of the transport unit 120, thereby ensuring that the transport device 100 can successfully obtain the material tray to be tested in any supply bin 210, and can also successfully place the measured material tray in any unloading bin 220.

[0048] The driving mechanism 130 includes a first driving member 131 and a transmission member 132. The first driving member 131 is connected to the transport unit 120 through the transmission member 132 to drive the transport unit 120 to perform the transport operation. The first driving member 131 can be a power element such as a motor or a cylinder, and the transmission member 132 can be a transmission chain, a transmission belt, a transmission shaft, etc.

[0049] In this embodiment, the driving mechanism 130 also includes a first transmission wheel 133 and a second transmission wheel 134. The first transmission wheel 133 is installed at the driving end of the first driving member 131 and can rotate under the drive of the first driving member 131. The second transmission wheel 134 is connected to the conveying unit 120. The transmission member 132 is configured as a transmission belt and is sleeved on the first transmission wheel 133 and the second transmission wheel 134.

[0050] When performing the transport operation, the first driving member 131 drives the first transmission wheel 133 to rotate, and then drives the second transmission wheel 134 to rotate through the transmission belt, and finally drives the transport unit 120 to move along a preset track through the second transmission wheel 134 to achieve transport. Among them, the second transmission wheel 134 can directly drive the transport unit 120 to make a circular motion, or cooperate with the lead screw pair to drive the transport unit 120 to make a linear motion, or cooperate with the cam assembly to drive the transport unit 120 to make a rotation or linear reciprocating motion, which is not limited here and can be set according to the actual application scenario.

[0051] Furthermore, in the present embodiment, the driving mechanism 130 further includes a screw rod 135 and a nut seat 136. The screw rod 135 extends along a preset direction and is connected to the second transmission wheel 134. The nut seat 136 is screwed to the screw rod 135 and is connected to the transport unit 120. The rotation of the second transmission wheel 134 can drive the screw rod 135 to rotate, thereby driving the nut seat 136 to move along the screw rod 135, and then driving the transport unit 120 connected to the nut seat 136 to move along the preset direction to perform the transport operation. The nut seat 136 cooperates with the screw rod 135 to convert the circular motion of the second transmission wheel 134 into the linear motion of the transport unit 120, which can improve the stability and feeding accuracy of the transport unit 120 during the movement process.

[0052] The brake mechanism 140 includes a second driving member 141, an elastic member 142 and a brake member 143. The brake member 143 abuts against the transmission member 132 under the action of the elastic member 142, and the second driving member 141 has a first state of driving the brake member 143 and a second state of releasing the brake member 143 from moving.

[0053] The elastic member 142 can be a spring, a spring sheet, a gas spring or other element capable of elastic energy storage, which can provide a pre-tightening force to the brake member 143 and make the brake member 143 have a tendency to approach the transmission member 132. The first state is when the second driving member 141 starts working. In the first state, the second driving member 141 overcomes the force of the elastic member 142 and drives the brake member 143 to separate from the transmission member 132. When the second driving member 141 is not working, it is the second state. In the second state, the second driving member 141 releases the driving action on the brake member 143, so that the brake member 143 abuts against the transmission member 132 under the action of the elastic member 142.

[0054] The second driving member 141 may be a single-acting cylinder, and its piston rod retracts and drives the brake member 143 to separate from the transmission member 132 when air is supplied, and extends its piston rod after air is cut off, and the brake member 143 abuts against the transmission member 132 under the action of the elastic member 142. Of course, when the installation position of the second driving member 141 changes, the second driving member 141 may extend its piston rod and drive the brake member 143 to separate from the transmission member 132 when air is supplied, and retract its piston rod after air is cut off, and the brake member 143 abuts against the transmission member 132 under the action of the elastic member 142.

[0055] like Figure 4 As shown, under normal working conditions, the first driving member 131 and the second driving member 141 are both started, and the second driving member 141 is in the first state. At this time, the second driving member 141 overcomes the preload force of the elastic member 142 to drive the brake member 143 to separate from the transmission member 132, and the first driving member 131 drives the transport unit 120 to perform the transport operation through the transmission member 132.

[0056] like Figure 5 As shown, when encountering special working conditions such as power failure and gas failure, the first driving member 131 and the second driving member 141 will both stop, and the second driving member 141 will be in the second state. At this time, the transport unit 120 will not stop immediately due to inertia, but will continue to move and drive the transmission member 132 to continue to rotate, and the brake member 143 will abut against the transmission member 132 under the action of the elastic member 142. The brake member 143 can gradually stop the transmission member 132 through friction, so that the transport unit 120 can be smoothly switched to a stationary state, which can avoid large vibrations of the transport unit 120 caused by instantaneous stop, and can improve stability under special working conditions.

[0057] The brake member 143 can be configured as a friction block, a friction roller, etc. Specifically, in this embodiment, the brake member 143 is configured as a brake wheel, which can roll along the transmission member 132 when in contact with the transmission member 132. The brake wheel can rotate, and will encounter greater resistance during the rotation process. In this way, the transmission member 132 can be braked while the wear on the transmission member 132 can be reduced.

[0058] In addition, in other embodiments, the brake member 143 may also be configured in the form of two clamping blocks (not shown) that cooperate with each other. The two clamping blocks are respectively located on both sides of the transmission member 132 and can approach each other and abut against the transmission member 132 under the action of the elastic member 142, thereby clamping the transmission member 132 to achieve braking. When the second driving member 141 is in the first state, it can overcome the force of the elastic member 142 and separate the two clamping blocks from each other.

[0059] Please refer again Figure 3 , Figure 4 and Figure 5In this embodiment, the braking mechanism 140 also includes a connecting rod 144, the middle part of the connecting rod 144 is rotatably mounted on the transport base 110, the braking member 143 is mounted on the connecting rod 144, the second driving member 141 is connected to the connecting rod 144 and can drive the connecting rod 144 to rotate forward to drive the braking member 143 to separate from the transmission member 132, and the elastic member 142 is connected to the connecting rod 144 and can drive the connecting rod 144 to rotate reversely to drive the braking member 143 to abut against the transmission member 132.

[0060] Specifically, the connecting rod 144 can be rotatably mounted on the transport base 110 via a pin or a hinge, and the location of the pin or the hinge is the rotation point of the connecting rod 144. The connecting rod 144 can rotate forward or reverse around the rotation point, and the forward rotation and the reverse rotation are relative. Figure 3 As shown in the example, the connecting rod 144 rotates clockwise to drive the brake member 143 to separate from the transmission member 132, so it is a positive rotation, while the connecting rod 144 rotates counterclockwise to drive the brake member 143 to abut against the transmission member 132, so it is a reverse rotation.

[0061] Specifically, the elastic member 142 is configured as a tension spring, and the two ends of the tension spring are respectively connected to the connecting rod 144 and the transport seat 110, and the preload force generated by the tension of the tension spring can drive the connecting rod 144 to rotate in the opposite direction. Obviously, in other embodiments, the elastic member 142 can also be configured as a spring or compression spring with one end abutting against the transport seat 110 and the other end abutting against the connecting rod 144, or configured as a torsion spring located at the rotation point of the connecting rod 144.

[0062] The brake member 143 can move in a circular motion along with the connecting rod 144, thereby moving away from or close to the transmission member 132. Moreover, the space required for the brake member 143 to move in a circular motion is smaller than that required for the linear motion, so the space required for the brake mechanism 140 can be reduced.

[0063] In addition, it should be noted that, in other embodiments, the brake member 143 may also be replaced by the above-mentioned connecting rod 144. That is, the connecting rod 144 as a whole may be used as the brake member 143, and one end of the connecting rod 144 is used to abut against the transmission member 132 to achieve braking.

[0064] Furthermore, in this embodiment, the elastic member 142 is connected to the connecting rod 144 at a first connection on the connecting rod 144, the first connection and the brake member 143 are respectively located on both sides of the rotation point of the connecting rod 144, and the distance between the first connection and the rotation point is greater than the distance between the rotation point and the brake member 143. In this way, the connecting rod 144 is equivalent to a labor-saving lever, and the elastic member 142 only needs a small pre-tightening force to hold the brake member 143 against the transmission member 132 through the connecting rod 144, so the braking effect is better.

[0065] Furthermore, in this embodiment, the second driving member 141 is connected to the connecting rod 144 at the second connection of the connecting rod 144, and the second connection is located between the first connection and the rotation point. In other words, the second connection is closer to the rotation point than the first connection, so the force arm of the second driving member 141 is shorter than the force arm of the elastic member 142.

[0066] After the second driving member 141 encounters a special working condition and stops, it generally does not reset immediately. The elastic member 142 needs to overcome the resistance of the second driving member 141 to force the connecting rod 144 to rotate in the opposite direction and force the second driving member 141 to reset to drive the brake member 143 to abut against the transmission member 132. Since the elastic member 142 has a long force arm, the elastic member 142 can quickly overcome the resistance of the second driving member 141 and force the connecting rod 144 to rotate in the opposite direction.

[0067] In the above-mentioned handling device 100 and the test sorting equipment 10, under normal working conditions, the first driving member 131 and the second driving member 141 are both started, the second driving member 141 is in the first state and drives the brake member 143 to separate from the transmission member 132, and the first driving member 131 drives the handling unit 120 through the transmission member 132 to perform the handling operation. When encountering special working conditions such as power failure and gas failure, the first driving member 131 and the second driving member 141 are both shut down, and the second driving member is in the second state. At this time, the handling unit 120 will not stop immediately due to inertia, but will continue to move and drive the transmission member 132 to continue to rotate, and the brake member 143 will abut against the transmission member 132 under the action of the elastic member 142. The brake member 143 gradually stops the transmission member 132 through friction, so that the handling unit 120 is smoothly switched to a stationary state to avoid large vibrations caused by instantaneous stops. Therefore, the above-mentioned handling device 100 and the test sorting equipment 10 have high stability under special working conditions.

[0068] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
