The upper module is arranged on the lifting mechanism, and the lifting mechanism drives the upper module to do lifting and lowering motion.

[0040] like Figure 1 , Figure 2 , Figure 5As shown, a PCB board test module 1 provided in an embodiment of the present invention is suitable for use in a program burning test machine. Specifically, the PCB board test module 1 in this embodiment includes a lifting mechanism 11, an upper module 12, a linear motion module 13 and a lower module 14. The upper module 12 is arranged on the lifting mechanism 11 and is driven by the lifting mechanism 11 to perform lifting and lowering movements. The first end of the linear motion module 13 is located below the upper module 12, and the second end of the linear motion module 13 extends to the side of the upper module 12. The lower module 14 is fixedly installed on the linear motion module 13 and is driven by the linear motion module 13 to perform reciprocating movements along the length direction of the linear motion module 13. The upper module 12 includes An upper fixing plate 122, an upper test main board 123, an upper template 121, a locking mechanism 15 and a separation mechanism 16, wherein the upper fixing plate 122 is arranged on the lifting mechanism 11, the upper test main board 123 is arranged on the upper surface of the upper template 121, the upper template 121 is detachably mounted on the lower surface of the upper fixing plate 122, the locking mechanism 15 is fixed on the upper fixing plate 122 and is used to lock the upper template 121 on the lower surface of the upper fixing plate 122, and the separation mechanism 16 is fixed on the upper fixing plate 122 and is used to separate the upper template 121 from the lower surface of the upper fixing plate 122;

[0041] The lower mold assembly 14 includes a lower fixed plate 142, a lower mold plate 141, a clamping mechanism 17 and a lifting mechanism 18. The clamping mechanism 17 is fixedly connected to the lower fixed plate 142 and is used to press the lower mold plate 141 onto the lower fixed plate 142. The lifting mechanism 18 is fixedly connected to the upper fixed plate 122 and is used to lift the lower mold plate 141 from the lower fixed plate 142.

[0042] In this embodiment, a locking mechanism 15 is provided on the upper fixing plate 122, and the locking mechanism 15 locks the upper template 121 to the lower surface of the upper fixing plate 122, and also locks the upper test main board 123, so that in the PCB board test module 1, the upper template 121 can be quickly and automatically locked and unlocked; the separation mechanism 16 can separate the upper template 121 and the upper test main board 123 arranged on the upper template 121 from the upper fixing plate 122, and automatically separate the upper template 121 and the upper test main board 123. Through the cooperation of the locking mechanism 15 and the separation mechanism 16, the speed of locking and separating the upper template 121 and the upper test main board 123 of the PCB board test module 1 is accelerated, and the replacement speed of the upper template 121 and the upper test main board 123 is accelerated. The clamping mechanism 17 can press the lower template 141 against the upper surface of the lower fixing plate 142, so that the lower template 141 is locked; the lifting mechanism 18 can lift the lower template 141, so as to separate the lower template 141 from the upper surface of the lower fixing plate 142. Through the cooperation of the clamping mechanism 17 and the lifting mechanism 18, the speed of locking and separating the lower template 141 of the PCB board test module 1 is accelerated, and the installation and replacement speed of the lower template 141 is accelerated.

[0043] The working process of the PCB board test module 1 of the present embodiment includes the disassembly and installation process of the upper test mainboard 123 and the upper template 121, and the disassembly and installation process of the lower template 141. In the process of installing the upper test mainboard 123 and the upper template 121, the upper test mainboard 123 is first fixed to the upper surface of the upper template 121, and the upper template 121 is then placed on the lower module 14; then, the lower module 14 is driven by the linear motion module 13 to move to the bottom of the upper fixed plate 122, and the upper test mainboard 123 and the upper template 121 are also brought to the bottom of the upper fixed plate 122; then, the two locking mechanisms 15 start working, and the upper template 121 and the upper test mainboard 123 are locked to the lower surface of the upper fixed plate 122, thereby realizing the automatic installation of the upper template 121 and the upper test mainboard 123. During the process of disassembling the upper template 121 and the upper test main board 123, first, the linear motion module 13 drives the lower module 14 to move to the bottom of the upper template 121 so as to receive the upper template 121; then, the locking mechanism 15 unlocks the upper template 121, and the separation mechanism 16 pushes the upper template 121 and the upper test main board 123 to move downward, so that the upper template 121 is separated from the upper fixed plate 122 and falls onto the lower module 14; finally, the linear motion module 13 drives the lower module 14 to move so as to transport the upper template 121 and the upper test main board 123 from under the upper fixed plate 122 to outside the upper fixed plate 122. In this embodiment, the locking mechanism 15 and the separation mechanism 16 automatically disassemble and install the upper template 121 and the upper test main board 123, and the upper template 121 and the upper test main board 123 are moved to the second end of the linear motion module 13 through the linear motion module 13, and the linear motion module 13 also moves the lower module 14 to the second end of the linear motion module 13, and the lower template 141 is disassembled and installed at the second end of the linear motion module 13. Therefore, the upper template 121, the upper test main board 123 and the lower template During the replacement process of 141, what we need to do is to load the upper template 121 and the lower template 141 with the upper test mainboard 123 to the second end of the linear motion module 13 and unload the upper template 121 and the lower template 141 with the upper test mainboard 123 from the second end of the linear motion module 13, to avoid directly manually disassembling and installing the upper template 121, the upper test mainboard 123 and the lower template 141. This embodiment fully automatically replaces the upper template 121, the upper test mainboard 123 and the lower template 141, and the replacement speed is fast.

[0044] During the installation of the lower template 141, the lower template 141 is placed on the lower fixed plate 142, and the clamping mechanism 17 then presses the lower template 141 against the upper surface of the lower fixed plate 142; during the removal of the lower template 141, the lifting mechanism 18 lifts the lower template 141 from the upper surface of the lower fixed plate 142, thereby separating the lower template 141 from the lower fixed plate 142, completing the removal of the lower template 141.

[0045] In this embodiment, the locking mechanism 15 and the separation mechanism 16 automatically lock the upper template 121 and automatically separate the upper template 121, and transport the upper template 121 and the upper test mainboard 123 through the linear motion module 13. At the same time, the pressing mechanism 17 and the lifting mechanism 18 can automatically disassemble and install the lower template 141. The entire replacement process does not require manual participation, thereby improving work efficiency. When the PCB board test module 1 of this embodiment is applied to a program burning test machine, multiple PCB board test modules 1 are densely distributed in the program burning test machine. Under such dense distribution, the disassembly and installation tools have a small working space, and it is difficult to manually replace the upper template 121, the upper test mainboard 123 and the lower template 141, and the replacement speed is slow. The PCB board test module 1 of this embodiment does not require manual use of tools, and fully automatically replaces the upper template 121, the upper test mainboard 123 and the lower template 141, with fast replacement speed and efficiency.

[0046] like Figure 4 As shown, in order to accurately locate the connection position between the upper fixing plate 122 and the upper template 121, the upper fixing plate 122 and the upper template 121 are positioned by installing the positioning pins 1213. Since the positioning pins 1213 are installed to fit tightly, it is difficult to separate the upper template 121 from the upper fixing plate 122. When the locking mechanism 15 is in the unlocked state, the separation mechanism 16 can push the upper template 121 to move downward, thereby automatically separating the upper template 121 from the upper fixing plate 122, thereby reducing the difficulty of disassembling the upper template 121 and the upper test main board 123.

[0047] Specifically, in this embodiment, one locking mechanism 15 or two locking mechanisms 15 can be provided, and both can realize the locking function of the upper template 121. Relatively speaking, two locking mechanisms 15 can ensure the force balance of the upper template 121. When two locking mechanisms 15 are provided, the two locking mechanisms 15 are respectively provided on two opposite sides of the upper fixed plate 122. In this embodiment, one separation mechanism 16 or two separation mechanisms 16 can be provided, and both can realize the locking function of the upper template 121. Relatively speaking, two separation mechanisms 16 can ensure the force balance of the upper template 121. When two separation mechanisms 16 are provided, the two separation mechanisms 16 are respectively provided on two opposite sides of the upper fixed plate 122.

[0048] Specifically, the present embodiment is provided with four clamping mechanisms 17, which are respectively arranged at the four corners of the lower fixing plate 142. In the present embodiment, a lifting mechanism 18 is provided, which is located below the middle of the lower fixing plate.

[0049] In this embodiment, when installing the upper template 121, the lifting mechanism 11 drives the upper fixing plate 122 to do lifting movement, thereby adjusting the distance between the locking mechanism 15 and the upper template 121, so that the second end of the swing rod 151 can just penetrate into the lower surface of the upper template 121 when swinging to support the upper template 121, thereby pushing the upper template 121 to rise. At the same time, when disassembling the upper template 121, the lifting mechanism 11 can drive the upper fixing plate 122 to do lifting movement, thereby adjusting the distance between the upper template 121 and the lower module 14, reducing the height of the upper template 121 and the upper test mainboard 123 falling, and avoiding damage to the upper template 121 and the upper test mainboard 123.

[0050] Optionally, specifically, the lifting mechanism 11 includes a plurality of vertically parallel guide posts 111, a top plate 112 disposed on the upper ends of the guide posts 111, and a lifting cylinder 113 fixed on the top plate 112. The upper fixed plate 122 is slidably sleeved on the guide posts 111, and the output end of the lifting cylinder 113 is connected to the upper fixed plate 122 to drive the upper fixed plate 122 to perform lifting motion along the guide posts 111, thereby realizing that the lifting mechanism 11 drives the upper die set 12 to perform lifting motion.

[0051] Alternatively, if Figure 3 , Figure 4As shown, the locking mechanism 15 includes a swing rod 151, an articulated seat 152 and a traction member 153. The articulated seat 152 is fixed to the edge of the upper fixed plate 122. The middle part of the swing rod 151 is hinged to the articulated seat 152. The first end of the swing rod 151 extends to the middle of the upper fixed plate 122. The second end of the swing rod 151 extends downward and bends to the lower surface of the upper template 121. The traction member 153 is fixed to the upper fixed plate 122 and connected to the first end of the swing rod 151 and has the function of traction to traction the first end of the swing rod 151 to swing upward or downward. In this embodiment, the traction member 153 is connected to the first end of the swing rod 151 and traction the first end of the swing rod 151 to swing upward or downward. When the first end of the swing rod 151 swings, it drives the second end of the swing rod 151 to swing around the hinge point between the middle part of the swing rod 151 and the hinge seat 152. Since the second end of the swing rod 151 first extends downward and then bends toward the lower surface of the upper template 121 and the hinge seat 152 is fixed to the edge of the upper fixed plate 122, the end of the second end of the swing rod 151 and the abutment position of the upper template 121 are located below the hinge seat 152 and close to the middle of the upper template 121. During use, when the traction member 153 pulls the first end of the swing rod 151 to swing upward, the second end of the swing rod 151 swings downward, so that the tip of the second end of the swing rod 151 moves toward the inner side of the upper template 121 and moves upward, and the tip of the second end of the swing rod 151 pushes the upper template 121 to move upward, thereby quickly locking the upper template 121 to the lower surface of the upper fixed plate 122; when the traction member 153 pulls the first end of the swing rod 151 to swing downward, the second end of the swing rod 151 swings upward, so that the tip of the second end of the swing rod 151 moves toward the outer side of the upper template 121 and moves downward, and the tip of the second end of the swing rod 151 releases the upper template 121, thereby facilitating the separation of the upper template 121 from the upper fixed plate 122. In this embodiment, through the cooperation of the traction member 153 and the swing rod 151, the upper template 121 can be quickly locked and the locking state between the upper template 121 and the upper fixed plate 122 can be quickly released, which greatly speeds up the disassembly and replacement speed of the upper template 121 and the upper test main board 123 located between the upper template 121 and the upper fixed plate 122, thereby improving production efficiency.

[0052] Specifically, since the upper template 121 and the upper fixed plate 122 are positioned and installed by installing the positioning pins 1213, the matching tolerance of the installation positioning pins 1213 itself makes it necessary to apply appropriate force to the connection between the upper template 121 and the upper fixed plate 122 in order to completely install the upper template 121 on the lower surface of the upper fixed plate 122. Usually, the upper template 121 is fixedly installed by locking the upper template 121 with screws. In this embodiment, the upper template 121 is fixed to the lower surface of the upper fixed plate 122 together with the upper test main board 123 by the locking mechanism 15, avoiding the use of manual screwing to lock the upper template 121, reducing manual participation, and speeding up the locking of the upper template 121.

[0053] In other embodiments of the locking mechanism 15, the locking mechanism 15 is a pneumatic clamping finger and a moving mechanism. The moving mechanism moves with the upper fixed plate 122 and drives the pneumatic clamping finger to move to the upper fixed plate 122 or away from the upper fixed plate 122. The pneumatic clamping finger is fixed on the moving mechanism. The pneumatic clamping finger is provided with two clamping fingers that can clamp and move. The clamping fingers perform clamping movement, thereby locking the upper template 121 to the lower surface of the upper fixed plate 122.

[0054] Furthermore, if Figure 2As shown, the lower surface of the upper mold plate 121 is provided with a test positioning pin 1211 extending downward and inserted into the lower mold assembly 14 and a limit pin 1212 extending downward and abutting against the lower mold assembly 14 , and the limit pin 1212 is shorter than the test positioning pin 1211 . In the process of automatically installing the upper test mainboard 123 and the upper template 121, the upper test mainboard 123 is first fixed to the upper surface of the upper template 121, and the upper template 121 is then placed on the lower module 14, and the test positioning pin 1211 is matched and connected with the lower module 14, and the limit pin 1212 abuts against the lower module 14, so that the upper template 121 and the lower module 14 maintain a distance; then, the lower module 14 is driven by the linear motion module 13 to move to the bottom of the upper fixed plate 122, and the upper test mainboard 123 and the upper template 121 are also brought to the bottom of the upper fixed plate 122; then, the two locking mechanisms 15 start working, and the two traction members 153 pull the first ends of the two swing rods 151 to swing upward, and the second ends of the two swing rods 151 extend into the gap between the upper template 121 and the lower module 14, and the upper template 121 is connected to the upper test mainboard 123 and locked together, thereby realizing the automatic installation of the upper template 121 and the upper test mainboard 123. In this embodiment, the upper template 121 and the upper test main board 123 are transported by the linear motion module 13, and the upper template 121 and the upper test main board 123 are transported to the bottom of the upper fixed plate 122, and by setting a test positioning pin 1211 and a limit pin 1212 on the lower surface of the upper template 121, a gap is created between the upper template 121 and the lower module 14, so that the second end of the swing rod 151 can extend into the gap between the upper template 121 and the lower module 14, thereby realizing automatic installation of the upper template 121 and the upper test main board 123.

[0055] During the process of automatically disassembling the upper template 121 and the upper test main board 123, first, the linear motion module 13 drives the lower module 14 to move to the bottom of the upper template 121 so as to receive the upper template 121; then, the traction member 153 in the locking mechanism 15 pulls the first end of the swing rod 151 to swing downward, so that the second end of the swing rod 151 swings outward and disengages from the upper template 121; then, the separation mechanism 16 starts working, and the push rod of the first cylinder pushes the upper template 121 to move downward, so that the upper template 121 is separated from the upper fixed plate 122 and falls onto the lower module 14; finally, the linear motion module 13 drives the lower module 14 to move, so as to transport the upper template 121 and the upper test main board 123 from under the upper fixed plate 122 to outside the upper fixed plate 122.

[0056] Furthermore, in this embodiment, preferably, the opposite side edges of the upper fixing plate 122 are provided with locking mechanisms 15 for locking the upper template 121 to the lower surface of the upper fixing plate 122 . Two sets of locking mechanisms 15 are provided to facilitate force balance of the upper template 121 .

[0057] Alternatively, if Figure 3 As shown, the number of the articulated seats 152 and the number of the swinging rods 151 are both two, and the two articulated seats 152 are arranged side by side. The locking mechanism 15 also includes an articulated rod 154 and a connecting rod 155. The two ends of the articulated rod 154 are respectively penetrated on the two articulated seats 152, and the two ends of the articulated rod 154 are respectively hinged to the middle of the two swinging rods 151, the two ends of the connecting rod 155 are respectively connected to the first ends of the two swinging rods 151, and the traction member 153 is connected to the middle of the connecting rod 155. When a single swinging rod 151 locks the upper template 121, there is a problem that the swinging rod 151 cannot stably support the upper template 121. In this embodiment, by providing two swinging rods 151, and driving the two swinging rods 151 to swing at the same time through the connecting rod 155, the second ends of the two swinging rods 151 can synchronously lock the upper template 121 or synchronously release the locking of the upper template 121, and the second ends of the two swinging rods 151 can stably support the upper template 121.

[0058] Further, in this embodiment, the traction member 153 is a power element or elastic element capable of pulling the first end of the swing rod 151 to swing, such as the power element is a cylinder, a hydraulic cylinder, etc., and the elastic element is a compression spring. The traction member 153 is fixed on the upper fixed plate 122, and the upper end of the traction member 153 is connected to the first end of the swing rod 151, so as to pull the first end of the swing rod 151 to swing.

[0059] Alternatively, if Figures 2 to 4 As shown, the locking mechanism 15 also includes a first fixed seat 156, and the traction member 153 is a first cylinder. The first cylinder is fixed on the first fixed seat 156 and is located between the first ends of the two swing rods 151. The push rod of the first cylinder extends downward and is connected to the middle of the connecting rod 155. The push rod of the first cylinder can be automatically extended and retracted. Compared with the compression spring, it has a higher degree of automation and is faster to disassemble and replace the upper template 121 and the upper test main board 123. In addition, in order to accurately locate the position between the upper fixed plate 122 and the upper template 121, the upper fixed plate 122 and the upper template 121 are positioned by installing the positioning pin 1213. Due to the tight fit of the installation of the positioning pin 1213, it takes a large force to lock the upper template 121 to the lower surface of the upper fixed plate 122, and the first cylinder can apply a large force to the swing rod 151, so that the second end of the swing rod 151 can exert a large force to support and push the upper template 121 upward to lock the upper template 121.

[0060] Alternatively, if Figure 3 , Figure 4As shown, elastic members 157 are provided on both sides of the first fixed seat 156, and the upper ends of the two elastic members 157 are respectively connected to the two sides of the first fixed seat 156, and the lower ends of the two elastic members 157 are respectively connected to the first ends of the two swing rods 151. In this embodiment, the two ends of the elastic member 157 are respectively connected to the corresponding sides of the first fixed seat 156 and the first ends of the corresponding swing rods 151, and the elastic member 157 can continuously apply a force to swing the first end of the swing rod 151 upward, so that the second end of the swing rod 151 can continuously support the upper template 121, so that when the traction member 153 suddenly loses power (such as the loss of air pressure in the first cylinder), the force can be supplemented in time to support the upper template 121, so as to prevent the upper template 121 from detaching from the lower surface of the upper fixed plate 122 and causing the upper template 121 and the upper test main board 123 to break.

[0061] Furthermore, both sides of the first fixing seat 156 are provided with fixing parts extending to the upper end of the corresponding swing rod 151, and the upper ends of the two elastic members 157 are respectively connected to the two fixing parts.

[0062] In this embodiment, the elastic member 157 is a tension spring or an elastic rubber band, and a tension spring is preferred in this embodiment.

[0063] Alternatively, if Figure 4 As shown, the lower end of the push rod of the first cylinder is provided with a hinge 158, the upper end of the hinge 158 is hinged to the lower end of the push rod of the first cylinder, and the lower end of the hinge 158 is connected to the connecting rod 155. Since the first end of the swing rod 151 is swinging, the motion trajectory of the connecting rod 155 is arc-shaped, while the motion trajectory of the push rod of the first cylinder is a straight line, so there will be motion interference between the push rod of the first cylinder and the connecting rod 155. In this embodiment, by providing the hinge 158 at the lower end of the push rod of the first cylinder, the motion interference between the push rod of the first cylinder and the connecting rod 155 is avoided.

[0064] Alternatively, if Figure 4 As shown, the separation mechanism 16 includes a second fixing seat 161 and a second cylinder 162, the second fixing seat 161 is fixed on the upper fixing plate 122, the second cylinder 162 is fixed on the second fixing seat 161, and the push rod of the second cylinder 162 extends downward and passes through the upper fixing plate 122 and abuts against the upper template 121. In the separation mechanism 16 of this embodiment, the push rod of the second cylinder 162 abuts against the upper template 121, thereby pushing the upper template 121 to move downward, so that the upper template 121 is separated from the upper fixing plate 122, and the upper template 121 is unlocked.

[0065] Specifically, in this embodiment, the push rod of the second cylinder 162 abuts against the upper test main board 123, and the push rod pushes the upper test main board 123 to move, thereby separating the upper template 121 and the upper test main board 123 from the upper fixing plate 122. In this embodiment, a through hole for avoiding the push rod of the second cylinder 162 can also be provided on the upper test main board 123, so that the push rod of the second cylinder 162 passes through the through hole and directly abuts against the upper template 121.

[0066] In other embodiments of the separation mechanism 16, the separation mechanism 16 includes a motor and a screw. The motor is fixed to the upper fixed plate 122. The screw passes through the upper fixed plate 122 and extends downward and is threadedly connected to the upper template 121. The motor drives the screw to rotate, and the screw drives the upper template 121 to perform a lifting movement, thereby separating the upper template 121 from the upper fixed plate 122.

[0067] Alternatively, if Figures 2 to 4 As shown, an upper connection seat 124 is provided at the edge of the upper fixing plate 122, and a plurality of upper elastic probes 125 extending downward and abutting against the upper test main board 123 are provided on the upper connection seat 124, and a plurality of upper conductive contacts 1231 corresponding to each of the upper elastic probes 125 are provided on the upper test main board 123. In this embodiment, the upper connection seat 124 is fixed on the upper fixing plate 122, and each of the upper elastic probes 125 on the upper connection seat 124 can smoothly extend downward to the upper test main board 123, and each of the upper elastic probes 125 on the upper connection seat 124 elastically abuts against each of the upper conductive contacts 1231 on the upper test main board 123, so that each of the upper elastic probes 125 can be stably connected to the upper test main board 123, and further, the test card 5 can be stably electrically connected to the upper test main board 123. When the upper test mainboard 123 is disassembled, the upper test mainboard 123 can be automatically separated from each upper elastic probe 125 on the upper connection seat 124, and when the upper test mainboard 123 is installed, the upper test mainboard 123 can be automatically connected to each upper elastic probe 125 on the upper connection seat 124. Therefore, in this embodiment, when replacing the upper test mainboard 123, there is no need to disassemble the test card 5 and the upper connection seat 124, thereby eliminating the disassembly and installation process of the test card 5 and the upper connection seat 124, and the replacement speed of the upper test mainboard 123 is faster.

[0068] Furthermore, if Figure 4As shown, the upper fixing plate 122 is provided with an upper mounting groove 1221 for fixing and mounting the upper connecting seat 124, and a plurality of upper conductive contacts 1231 corresponding to each upper elastic probe 125 are provided on the area of ​​the upper test main board 123 facing the upper mounting groove 1221, and the upper connecting seat 124 is fixed in the upper mounting groove 1221, and each upper elastic probe 125 abuts against each upper conductive contact 1231 in a one-to-one correspondence. In this embodiment, by providing the upper mounting groove 1221, the space occupied by the upper connecting seat 124 is reduced, and at the same time, it is convenient for each upper elastic probe 125 to pass through the upper fixing plate 122.

[0069] In this embodiment, the test card 5 can be connected to each upper elastic probe 125 through a wire. Alternatively, the test card 5 can be fixed on the upper connection seat 124 and the test card 5 is electrically connected to each upper elastic probe 125. More specifically, a plug-in slot (not shown in the figure) is provided on the upper connection seat 124, and the test card 5 is plugged into the plug-in slot.

[0070] When the test card 5 can be connected to each upper elastic probe 125 through a wire, as shown in the figure, the present embodiment is also provided with a socket (not shown in the figure) having multiple sockets, and multiple test cards 5 are concentrated in the socket, which is convenient for centralized management of each test card 5 and unified replacement of the test cards 5.

[0071] Furthermore, as shown in the figure, the upper fixing plate 122 and the upper template 121 are positioned and installed by installing positioning pins 1213, so that when the upper template 121 is fixed to the lower surface of the upper fixing plate 122, the upper elastic probe 125 can be accurately aligned with the upper conductive contact 1231.

[0072] Specifically, the installation positioning pin 1213 is fixed on the upper template 121 , and the upper end of the installation positioning pin 1213 passes through the upper test main board 123 and is connected to a pin hole (not shown in the figure) on the upper fixing plate 122 .

[0073] Alternatively, if Figure 2 As shown, the upper mold assembly 12 also includes an upper insulating plate 127 to prevent electrical connection between the upper test main board 123 and the upper fixing plate 122, and to prevent the upper fixing plate 122 from affecting the normal operation of the upper test main board 123. The upper insulating plate 127 is provided with a hollow groove (not shown) that passes through its upper and lower surfaces and faces the upper mounting groove 1221, and the lower end of the upper elastic probe 125 or the upper connecting seat 124 passes through the hollow groove.

[0074] In other embodiments of the upper insulating plate 127 , the upper insulating plate 127 is provided with a plurality of through holes penetrating the upper and lower surfaces thereof and corresponding one to one with each upper elastic probe 125 . Each upper elastic probe 125 passes through the corresponding through hole and abuts against an upper conductive contact 1231 on the upper test main board 123 .

[0075] Alternatively, if Figure 5 As shown, the clamping mechanism 17 includes a clamping rod 171 and a clamping cylinder 172 having an output rod, the clamping rod 171 is fixed to the upper end of the output rod and extends toward the lower template 141, and the clamping cylinder 172 is fixedly connected to the lower fixed plate 142 and is used to drive the output rod to perform lifting and rotational movements. In this embodiment, the clamping cylinder 172 drives the output rod to perform lifting and rotational movements, so that the clamping rod 171 can clamp or loosen the lower template 141, and the clamping cylinder 172 drives the output rod to perform rotational movements, so that the clamping rod 171 can move to the upper part of the lower template 141, or avoid the upper part of the lower template 141, so as to provide space for the disassembly and installation of the lower template 141.

[0076] Specifically, the clamping cylinder 172 is fixedly connected to the lower fixing plate 142 via a connecting piece 173 . One end of the connecting piece 173 is connected to the lower fixing plate 142 , and the other end extends outward. The clamping cylinder 172 is fixed to the connecting piece 173 .

[0077] Optionally, the lifting mechanism 18 includes a lifting cylinder with a lifting rod, which is arranged below the lower fixed plate 142. The lifting rod extends upward and passes through the lower fixed plate 142 and abuts against the lower template 141. When the lifting cylinder is working, the lifting rod moves upward to lift the lower template 141, so that the lower template 141 is separated from the lower fixed plate 142.

[0078] Specifically, the lifting cylinder is fixed to the lower surface of the lower fixing plate 142 , or the lifting cylinder is fixed to the linear moving module and is located below the lower fixing plate 142 and moves synchronously with the lower fixing plate 142 .

[0079] Alternatively, if Figure 2 As shown, the lower module 14 also includes a lower test mainboard 143, which is arranged on the upper surface of the lower fixing plate 142, and the lower template 141 is covered on the lower test mainboard 143. The lower test mainboard 143 is provided with a plurality of lower test pins extending upward and passing through the lower template 141. In the PCB board detection module of this embodiment, the lower module 14 has the original conveying function in conveying the PCB board. By arranging the lower test mainboard 143 in the lower module 14, the lower module 14 can test the lower surface of the PCB board, and cooperate with the upper module 12 to test the upper and lower surfaces of the PCB board at the same time, so that the PCB board test module 1 in this embodiment can adapt to more types of PCB boards and has diversified functions.

[0080] Specifically, in the present embodiment, in the lifting mechanism 18, the push rod of the lifting cylinder abuts against the lower test main board 143, and the push rod pushes the lower test main board 143 to move, thereby separating the lower test main board 143 and the lower template 141 from the lower fixing plate 142. In the present embodiment, a through hole for avoiding the push rod of the lifting cylinder can also be provided on the lower test main board 143, and the push rod of the lifting cylinder passes through the through hole and abuts against the lower template 141.

[0081] Alternatively, if Figure 1 , Figure 5 and Figure 6 As shown, the lower module 14 also includes at least one group of test interface components 144 arranged on the edge of the lower fixed plate 142, and each test interface component 144 includes a driving mechanism 1441, a guide rail 1442, a slider 1443 and at least one test interface 1444 arranged on the slider 1443 and electrically connected to the lower test main board 143, the guide rail 1442 is arranged on the edge of the lower fixed plate 142 and extends to the middle part of the lower fixed plate 142, the slider 1443 is slidably connected to the guide rail 1442, and the driving mechanism 1441 is fixed on the lower fixed plate 142 and connected to the slider 1443. In this embodiment, after the PCB board is placed on the lower template 141, the driving mechanism 1441 drives the slider 1443 to move along the guide rail 1442, and the slider 1443 drives the test interface 1444 to move toward the PCB board, and makes the test interface 1444 connected with the functional interface on the PCB board. The test main board is connected to the PCB board from the side of the PCB board through the test interface 1444, and the PCB board is tested, so that the PCB board test module 1 of this embodiment can adapt to the PCB board with a welded functional interface, and the PCB board with a welded functional interface is almost a finished PCB board, and the PCB board can be tested more comprehensively. At the same time, the upper test main board 123 and the lower test main board 143 also test the upper surface and the lower surface of the PCB board respectively, so as to further improve the detection of the PCB board.

[0082] In this embodiment, the slider 1443 can be provided with corresponding test interfaces 1444 according to the number of functional interfaces of the PCB board, and the position of the corresponding test interface 1444 can be adjusted according to the position of the functional interface of the PCB board.

[0083] Alternatively, if Figure 6 As shown, the edge of the lower fixing plate 142 is provided with grooves 1421 corresponding to the test interface components 144, the driving mechanism 1441 is arranged in the groove 1421, and the guide rail 1442 is arranged on the upper surface of the lower fixing plate 142 and located on one side of the groove 1421. In this embodiment, the driving mechanism 1441 is accommodated by the groove 1421, so as to avoid the test interface components 144 from being too protruding, and also avoid the driving mechanism 1441 from being too protruding and occupying the space on the upper surface of the lower template 141, so as to avoid the driving mechanism 1441 from affecting the test of the PCB board.

[0084] Alternatively, if Figure 5 , Figure 6 As shown, each test interface assembly 144 also includes a test interface seat 1445, the number of guide rails 1442 and the number of sliders 1443 are both two, the two guide rails 1442 are respectively arranged on both sides of the groove 1421, the two sliders 1443 are respectively slidably connected to the two guide rails 1442, the two ends of the test interface seat 1445 are respectively fixed on the two sliders 1443, and each test interface 1444 is fixed on the test interface seat 1445. In this embodiment, the two sliders 1443 are respectively guided to move by the double guide rails 1442, and the test interface seat 1445 spans the two sliders 1443, so that the test interface seat 1445 moves more accurately, thereby ensuring that the test interface 1444 can accurately match the functional structure on the PCB board. In addition, the two guide rails 1442 are respectively arranged on both sides of the groove 1421, so that the test interface seat 1445 has a longer length, which is convenient for arranging multiple test interfaces 1444 on the test interface seat 1445.

[0085] Optionally, the edges of the lower template 141 corresponding to each test interface assembly 144 are provided with a clearance groove 1411 for avoiding each guide rail 1442. The clearance groove 1411 on the lower template 141 avoids installation interference between the lower template 141 and the two guide rails 1442, and provides space for the fixed installation of each guide rail 1442.

[0086] Furthermore, the upper surface height of each guide rail 1442 is less than the upper surface height of the lower template 141. In this way, when each guide rail 1442 is located in the air avoidance groove 1411, each guide rail 1442 will not protrude from the upper surface of the lower template 141, thereby avoiding interference of the guide rail 1442 with the PCB board.

[0087] Alternatively, if Figure 5 , Figure 6As shown, a lower connection seat 145 is provided at one side edge of the lower fixing plate 142, and a plurality of lower elastic probes 146 extending upward to the lower test main board 143 are provided on the lower connection seat 145, and a plurality of lower conductive contacts corresponding to the lower elastic probes 146 are provided on the lower test main board 143. In this embodiment, the lower connection seat 145 is fixed on the lower fixing plate 142, and the lower elastic probes 146 on the lower connection seat 145 can smoothly extend upward to the lower test main board 143, and the lower elastic probes 146 on the lower connection seat 145 elastically abut against the lower conductive contacts on the lower test main board 143, so that the lower elastic probes 146 can be stably connected to the lower test main board 143, and further the test card 5 can be stably electrically connected to the lower test main board 143. When the lower test mainboard 143 is removed, the lower test mainboard 143 can be automatically separated from each lower elastic probe 146 on the lower connection seat 145, and when the lower test mainboard 143 is installed, the lower test mainboard 143 can be automatically connected to each lower elastic probe 146 on the lower connection seat 145. Therefore, in this embodiment, when the lower test mainboard 143 is replaced, the lower test mainboard 143 can be automatically disconnected from other electrical structures without removing the test card 5 and the lower connection seat 145, thereby eliminating the disassembly and installation process of the test card 5 and the lower connection seat 145, and the replacement speed of the lower test mainboard 143 is faster.

[0088] Alternatively, if Figure 6 As shown, the lower fixing plate 142 is provided with a lower mounting groove 1422 for fixing the lower connecting seat 145, and the lower connecting seat 145 is fixed in the lower mounting groove 1422. In this embodiment, by providing the lower mounting groove 1422, the space occupied by the lower connecting seat 145 is reduced, and at the same time, each lower elastic probe 146 is convenient to extend upward through the lower fixing plate 142.

[0089] Optionally, the lower module 14 also includes a lower insulating plate, which is arranged between the lower test main board 143 and the lower fixed plate 142, and is used to insulate the lower test main board 143 from the lower fixed plate 142 to avoid forming an electrical connection between the lower test main board 143 and the lower fixed plate 142, thereby preventing the lower fixed plate 142 from affecting the normal operation of the lower test main board 143.

[0090] In other embodiments of the lower insulating board, the lower insulating board is provided with a plurality of through holes penetrating the upper and lower surfaces thereof and corresponding to each lower elastic probe 146 . Each lower elastic probe 146 passes through the corresponding through hole and abuts against the lower conductive contact on the lower test main board 143 .

[0091] The present invention also provides a program burning test machine, such as Figure 7 , Figure 8As shown, the program burning test machine includes a work platform 2, on which at least one work group is arranged, each work group includes a gantry 3, a conveying mechanism 4 arranged on the crossbeam of the gantry 3 and moving along the crossbeam of the gantry 3, and a plurality of PCB board test modules 1 arranged below the gantry 3 and arranged side by side, and the second end of each linear motion module 13 extends below the moving track of the conveying mechanism 4. In this embodiment, the PCB board test module 1 can automatically disassemble and install the upper template 121 and the upper test main board 123, and automatically disassemble and install the lower template 141. After disassembling the upper template 121 and the upper test main board 123, the upper template 121 and the upper test main board 123 are transported to the second end of the linear motion module 13 through the linear motion module 13, and after the linear motion module 13 drives the lower module 14 to move to the second end of the linear motion module 13, the lower template 141 is disassembled, so that the lower template 141 is also located at the second end of the linear motion module 13. Since the second end of each linear motion module 13 extends below the moving track of the transport mechanism 4 , the transport mechanism 4 on the gantry 3 grabs the upper template 121 and the lower template 141 and transports the upper template 121 and the lower template 141 to a unified loading area.

[0092] Therefore, in the program burning test machine, the replacement process of the upper template 121, the upper test main board 123 and the lower template 141 includes an installation process and a disassembly process. During the installation process, firstly, multiple lower templates 141 are loaded into the loading area, and at the same time, the linear motion module 13 transports the lower fixed plate 142 to the second end of the linear motion module 13, and the transport mechanism 4 moves to the loading area and grabs the lower template 141. The transport mechanism 4 then transports the lower template 141 to the second end of the linear motion module 13 of one of the PCB board test modules 1 and places the lower template 141 on the lower fixed plate 142. Next, the clamping mechanism 17 clamps the lower template 141; fixes the upper test mainboard 123 on the upper template 121, and loads the upper template 121 to the loading area, the conveying mechanism 4 moves to the loading area and grabs the upper template 121, and the conveying mechanism 4 then transports the upper template 121 to the second end of the linear motion module 13 of the PCB board test module 1 and places the upper template 121 on the lower template 141, then, the linear motion module 13 drives the upper template 121 to move to the bottom of the upper fixed plate 122, and the locking mechanism 15 locks the upper template 121 to the lower surface of the upper fixed plate 122. During the disassembly process, the linear motion module 13 drives the lower module 14 to move to the first end of the linear motion module 13, the separation mechanism 16 separates the upper template 121, so that the upper template 121 falls onto the lower template 14, the linear motion module 13 drives the lower template 14 to move to the second end of the linear motion module 13, and finally the upper template 121 is transported away by the conveying mechanism 4; when disassembling the lower template 141, the linear motion module 13 drives the lower template 14 to move to the second end of the linear motion module 13, the lifting mechanism 18 lifts the lower template 141, and then the lower template 141 is transported away by the conveying mechanism 4. Through the cooperation of the conveying mechanism and the PCB board test module, the upper template 121 and the lower template 141 can be fully automatically loaded, installed, disassembled and unloaded. All the operator needs to do is to place the upper template 121 and the lower template 141 with the upper test mainboard 123 in the loading area, and to recover the upper template 121 and the lower template 141 with the upper test mainboard 123 in the unloading area. The replacement speed of the upper template 121, the upper test mainboard 123 and the lower template 141 is fast and efficient, avoiding the manual use of tools to replace the upper template, the upper test mainboard and the lower template.

[0093] In this embodiment, Figure 8As shown, the transport mechanism 4 includes a sliding assembly 41, a lifting assembly 42, and a grabbing assembly 43 disposed on the lifting assembly 42 and used to grab the PCB board. The sliding assembly 41 is disposed on the crossbeam to drive the lifting assembly 42 to move along the crossbeam. The lifting assembly 42 is fixedly mounted on the driving end of the sliding assembly 41 and is used to drive the grabbing assembly 43 to do lifting and lowering motion. In this embodiment, the sliding assembly 41 drives the lifting assembly 42 to move along the crossbeam, and the lifting assembly 42 drives the grabbing assembly 43 to do lifting and lowering motion, and the grabbing assembly 43 is disposed on the lifting assembly 42. Therefore, the sliding assembly 41 can drive the lifting assembly 42 and the grabbing assembly 43 to move to the loading area, the lifting assembly 42 drives the grabbing assembly 43 to move up and down to adjust the height so that the grabbing assembly 43 grabs the PCB board, and the sliding assembly 41 then drives the lifting assembly 42 and the grabbing assembly 43 to move to one of the PCB board test modules 1, and the lifting assembly 42 drives the grabbing assembly 43 to move up and down so that the grabbing assembly 43 places the PCB board on the second end of the linear motion module 13.

[0094] In this embodiment, the grabbing assembly 43 includes at least one suction cup.

[0095] In this embodiment, as shown in the figure, the lifting assembly 42 may include a lifting plate 421, a guide rod 422, a mounting plate 423 and a third cylinder 424. The lifting plate 421 is fixed to the third slider 412 or the fourth slider. The guide rod 422 is slidably connected to the lifting plate 421 through a linear bearing. The mounting plate 423 is connected to the lower end of each guide rod 422. The third cylinder 424 is fixed to the lifting plate 421 and the output push rod of the third cylinder 424 extends downward and is fixedly connected to the mounting plate 423. The grabbing assembly 43 is fixed to the mounting plate 423.
