[0037] In the description of the present application, if the first, second, etc. are described, it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the sequence of technical features indicated.

[0038] In the description of the present application, unless otherwise explicitly defined, the words such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0039] With reference to Figures 1 to 3 According to the circuit board core positioning and glue injection transfer mechanism 2 of the first aspect of the present application, the circuit board core positioning and glue injection transfer mechanism 2 comprises a workbench 10, a support frame 20, a transmission assembly 30 and a driving assembly 40. The workbench 10 has a glue injection station 11; the support frame 20 is arranged to reciprocally slide on the workbench 10, and both ends of the support frame 20 are configured to place material plates 21, and the material plates 21 are configured to carry circuit boards 1; the transmission assembly 30 is arranged to slide on the workbench 10, and the support frame 20 is arranged on the transmission assembly 30, and the transmission assembly 30 is configured to drive the support frame 20 to reciprocally slide on the workbench 10; and the driving assembly 40 is arranged on the workbench 10, and the driving assembly 40 is configured to drive the transmission assembly 30 to reciprocally slide on the workbench 10, so that both ends of the support frame 20 are alternately slid to the glue injection station 11 on the workbench 10.

[0040] It can be understood that the driving assembly 40 drives the transmission assembly 30 to reciprocally slide on the workbench 10 along the left-right direction shown in the figure, so that the transmission assembly 30 can drive the support frame 20 to reciprocally slide on the workbench 10, and then drive the material plates 21 at both ends of the support frame 20 to alternately slide to the glue injection station 11 on the workbench 10. Specifically, when one end (the left end shown in the figure) of the support frame 20 is located on the glue injection station 11, the circuit boards 1 on the material plates 21 can be injected with glue, and at this time, the material plates 21 at the other end (the right end shown in the figure) of the support frame 20 are outside the workbench 10, and at this time, the circuit boards 1 on the material plates 21 can be simultaneously unloaded and then loaded. When the circuit boards 1 on the glue injection station 11 are injected with glue, the transmission assembly 30 can be driven to make the support frame 20 move to the left, so that the material plates 21 at the left end of the support frame 20 slide out of the glue injection station 11 in the left direction, and the material plates 21 at the right end of the support frame 20 can move to the position of the glue injection station 11. This cycle is repeated to continuously perform the glue injection work.

[0041] Therefore, it can be understood that the circuit board core positioning and glue injection transfer mechanism 2 of the first aspect of the present application has at least the following beneficial effects: the support frame 20 reciprocally slides on the workbench 10 through the transmission assembly 30, so that the material plates 21 at both ends of the support frame 20 are alternately slid to the glue injection station 11, and thus the circuit boards 1 can be continuously injected with glue. At the same time, during the glue injection process, the circuit boards 1 on the material plates 21 that slide out of the glue injection station 11 can be unloaded and then loaded, thereby improving the production efficiency of the glue injection.

[0042] With reference toFigures 3 to 5 In some embodiments of the present application, the driving assembly 40 comprises a driving block 41 capable of rotating and sliding on the workbench 10, the transmission assembly 30 comprises a sliding seat 31 and a first clamping block 32, the sliding seat 31 is slidingly arranged on the workbench 10, the two sides of the supporting frame 20 are arranged on the sliding seat 31, and the first clamping block 32 is arranged with two blocks, the first clamping block 32 is rotationally arranged at the two ends of the sliding seat 31, and the driving block 41 can be sequentially clamped on the first clamping block 32, and the driving block 41 is configured to sequentially clamp the first clamping block 32, so that the first clamping block 32 drives the sliding seat 31 to reciprocate on the workbench 10.

[0043] Further, the driving assembly 40 and the transmission assembly 30 are further optimized and designed. The overall structure still takes the workbench 10 as the support basis, the supporting frame 20 is used to carry the material plate 21, and the driving assembly 40 and the transmission assembly 30 realize efficient and accurate reciprocating sliding of the supporting frame 20 on the workbench 10. First, the material plate 21 carrying the circuit board 1 is placed on the supporting frame 20. Start the driving assembly 40, and the driving assembly 40 drives the driving block 41 to start rotating on the workbench 10 along the preset track. When the driving block 41 slides to the right, until it slides to the position where a first clamping block 32 at the rear side is clamped, due to the clamping action between the driving block 41 and the first clamping block 32, the driving block 41 will drive the first clamping block 32 to rotate, and the first clamping block 32 is fixedly connected with the sliding seat 31, so as to drive the sliding seat 31 to slide along the right side of the slide rail (not marked in the figure) on the workbench 10. With the continuous sliding of the driving block 41, when it is disengaged from the clamping of the first clamping block 32, the sliding seat 31 stops sliding to the right at this time, and the material plate 21 at the left end of the supporting frame 20 slides to the glue injection station 11 for easy glue injection, and the material plate 21 at the right end of the supporting frame 20 slides out of the left side of the workbench 10 for easy feeding and discharging of the circuit board 1. After the driving block 41 is disengaged from the first clamping block 32, the driving block 41 continues to rotate along the rotating track after rotating, and moves to the left, and is clamped with another first clamping block 32 on the sliding seat 31. Similarly, another first clamping block 32 is driven to move by clamping, and in turn drives the sliding seat 31 to slide back (to the left), and finally drives the supporting frame 20 to move to the left. By sequentially clamping the two first clamping blocks 32 by the driving block 41, the reciprocating sliding of the sliding seat 31 on the workbench 10 is realized.

[0044] It should be noted that, from the first block of the first block 41 to the rotation process and to the carding process with another first carding block 32, the driving block 41 stops driving the sliding seat 31, at this time the support frame 20 is in the state of stop, and the two ends of the support frame 20 are located on the glue injection station 11 and the outside of the workbench 10 respectively, so that the circuit board 1 on the glue injection station 11 can be injected, and the circuit board 1 on the outside of the workbench 10 can be unloaded first and then loaded. When the two processes are completed at the same time, the driving block 41 is just connected with another first carding block 32, and the connected first carding block 32 can drive the sliding seat 31 to slide back, and then drive the support frame 20 to slide back, so that the material plate 21 on the outside of the workbench 10 slides to the glue injection station 11, and the material plate 21 on the glue injection station 11 slides to the outside of the workbench 10. Since the support frame 20 is installed on both sides of the sliding seat 31, the reciprocating sliding of the sliding seat 31 will drive the support frame 20 and the material plate 21 carrying the circuit board 1 on the support frame 20 to move, so that the two ends of the support frame 20 are alternately slid to the glue injection station 11, realizing the continuous injection of the circuit board 1.

[0045] Referring to Figures 3 to 5 In some embodiments of the application, the sliding seat 31 is provided with a rotating shaft 311, the rotating shaft 311 is rotatably arranged in the sliding seat 31, the first carding block 32 is rotatably arranged on the sliding seat 31 through one end of the rotating shaft 311, the first carding block 32 has a carding part 321, the carding part 321 is connected with the driving block 41, the other end of the rotating shaft 311 is provided with a second carding block 33, the second carding block 33 is rotatable, and the second carding block 33 is configured to drive the first carding block 32 to rotate, so that the guide inclined surface of the first carding block 32 is separated from the carding of the driving block 41.

[0046] Further, in the embodiment, the structure and connection relationship of the sliding seat 31, the first carding block 32 and the second carding block 33 are further optimized. The overall structure still takes the workbench 10 as the support basis, the support frame 20 is used to carry the material plate 21 of the circuit board 1, the driving assembly 40 provides power through the driving block 41, and the sliding seat 31, the first carding block 32 and the second carding block 33 of the transmission assembly 30 work cooperatively to realize the efficient and accurate reciprocating sliding of the support frame 20 on the workbench 10.

[0047] In actual work, first, the material plate 21 carrying the circuit board 1 is placed on the support frame 20. The driving assembly 40 is started, and the driving assembly 40 drives the driving block 41 to start rotating and sliding. When the driving block 41 rotates to the position of clamping the clamping part 321 of the first clamping block 32, the driving block 41 will drive the first clamping block 32 to slide synchronously due to the clamping effect between the driving block 41 and the first clamping block 32, so as to drive the sliding seat 31 to slide along the slide rail on the workbench 10. When it is needed to make the first clamping block 32 disengage from the clamping of the driving block 41, an external driving device (such as a cylinder, not shown in the figure) can be started, and the piston rod of the cylinder is extended to push the second clamping block 33 to rotate. Since the second clamping block 33 is connected with the first clamping block 32 through the rotating shaft 311, the rotation of the second clamping block 33 will drive the first clamping block 32 to rotate, so that the guide inclined surface of the first clamping block 32 gradually disengages from the clamping of the driving block 41. When the first clamping block 32 completely disengages from the clamping of the driving block 41, the driving block 41 continues to slide and rotate until another first clamping block 32 enters the clamping state, and the sliding seat 31 is driven to slide again. Through the cooperation of the driving block 41 clamping two first clamping blocks 32 in sequence and the second clamping block 33 driving the first clamping block 32 to disengage from the clamping, the reciprocating sliding of the sliding seat 31 on the workbench 10 is realized. Since the support frame 20 is installed on both sides of the sliding seat 31, the reciprocating sliding of the sliding seat 31 will drive the support frame 20 and the material plate 21 carrying the circuit board 1 on the support frame 20 to move together, so that the two ends of the support frame 20 are alternately slid to the glue injection station 11, and the continuous glue injection production of the circuit board 1 is realized.

[0048] Reference Figures 3 to 5 In some embodiments of the present application, the transmission assembly 30 further comprises two unlocking members 34, which are oppositely arranged on the workbench 10, and the positions of the two unlocking members 34 correspond to the positions of the second clamping blocks 33 one by one. The unlocking end of the unlocking member 34 can abut on the guide inclined surface of the second clamping block 33, and the unlocking member 34 is configured to drive the second clamping block 33 to rotate, so as to drive the first clamping block 32 to rotate.

[0049] Further, in order to facilitate the disengagement of the first clamping block 32 from the clamping of the driving block 41, the unlocking member 34 is additionally arranged in the transmission assembly 30 to drive the second clamping block 33, so as to control the rotation of the first clamping block 32.

[0050] The two unlocking pieces 34 are arranged on the workbench 10 in a relative manner, i.e., on the left and right sides of the workbench 10, and are distributed in front of and behind each other, and are arranged in a one-to-one corresponding manner with the positions of the two second clamping blocks 33 on the sliding seat 31. One end of the unlocking piece 34 is a fixed end, which is fixed on a pre-installed mounting seat (not marked in the figure) on the workbench 10 through a bolt or the like; the other end is an unlocking end, which is in the shape of a spherical surface, an arc surface or the like, and can abut against the guide inclined surface of the second clamping block 33. In the actual working process, when it is necessary to make the first clamping block 32 disengage from the clamping of the driving block 41, the driving assembly 40 drives the driving block 41 to drive the sliding seat 31 to move along the left and right directions and approach the unlocking end of the unlocking piece 34, respectively. When the sliding seat 31 approaches the unlocking end, the unlocking end of the unlocking piece 34 abuts against the guide inclined surface of the second clamping block 33. Due to the inclination angle of the guide inclined surface, the unlocking piece 34 exerts a tangential force on the second clamping block 33, so that the second clamping block 33 rotates around the rotating shaft 311. The rotation of the second clamping block 33 is transmitted to the first clamping block 32 through the rotating shaft 311, and the first clamping block 32 also rotates, so that the guide inclined surface of the first clamping block 32 gradually disengages from the clamping of the driving block 41. At this time, the driving block 41 continues to slide back and forth until the other first clamping block 32 enters the clamping state, and the sliding seat 31 is driven to slide again. Through the cooperative work of the driving block 41 clamping the two first clamping blocks 32 in sequence and the unlocking piece 34 driving the second clamping block 33 to make the first clamping block 32 disengage from the clamping, the reciprocating sliding of the sliding seat 31 on the workbench 10 is realized. Since the support frame 20 is installed on the two sides of the sliding seat 31, the reciprocating sliding of the sliding seat 31 will drive the support frame 20 and the material plate 21 carrying the circuit board 1 on the support frame 20 to move together, so that the two ends of the support frame 20 are alternately slid to the glue injection station 11, and the continuous glue injection production of the circuit board 1 is realized.

[0051] Further, with reference to Figures 3 to 5 In some embodiments of the present application, the unlocking piece 34 can be adjustably arranged on the workbench 10, so as to adjust the unlocking position of the unlocking end of the unlocking piece 34. The unlocking piece 34 can be screwed on the mounting seat arranged on the workbench 10, and the position of the unlocking end of the unlocking piece 34 can be adjusted by rotating the unlocking piece 34, so as to adjust the position of the unlocking piece 34 clamping the first clamping block 32 by the driving block 41, so as to adjust the stroke of the left and right sliding of the support frame 20, and finally satisfy the different specifications of the circuit board 1.

[0052] With reference to Figure 5 In some embodiments of the present application, the two ends of the sliding seat 31 are respectively provided with first limiting rods 312 arranged at intervals, the positions of the two first limiting rods 312 correspond to the positions of the first clamping blocks 32, the first clamping block 32 has a second limiting rod 322, the second limiting rod 322 can be clamped between the first limiting rods 312, and the first limiting rods 312 are configured to limit the rotation range of the first clamping block 32.

[0053] Further, first limiting rods 312 are arranged at intervals at both ends of the sliding seat 31, and a second limiting rod 322 is arranged on the first clamping block 32, so that the rotation range of the first clamping block 32 is limited by the cooperation of the first limiting rods 312 and the second limiting rod 322.

[0054] In actual work, first, the material plate 21 carrying the circuit board 1 is placed on the support frame 20. The driving assembly 40 is started to drive the driving block 41 to start rotating back. When the driving block 41 rotates to the position of clamping the clamping part 321 of the first clamping block 32, the driving block 41 will drive the first clamping block 32 to rotate due to the clamping effect between the driving block 41 and the first clamping block 32, so that the sliding seat 31 slides along the slide rail on the workbench 10. Taking the first clamping block 32 at the rear side in the figure as an example, when the driving block 41 clamps the first clamping block 32, the second limiting rod 322 arranged on the first clamping block 32 clamps the first limiting rod 312 on the left side at this time, so that the first clamping block 32 is prevented from rotating when the driving block 41 clamps the first clamping block 32, that is, due to the limiting effect of the first limiting rod 312, the second limiting rod 322 cannot continue to rotate, so that the rotation range of the first clamping block 32 is limited. This limitation can prevent the first clamping block 32 from rotating excessively, avoid abnormal clamping relationship between the first clamping block 32 and the driving block 41, and ensure the stability and reliability of the sliding of the sliding seat 31.

[0055] When it is necessary to make the first clamping block 32 disengage from the clamping with the driving block 41, an external control device (such as a controller) can send a signal to drive the driving device (such as a pneumatic cylinder, an electromagnet, etc.) arranged on the workbench 10 to act. The driving device pushes the unlocking piece 34 to move towards the second clamping block 33, and the unlocking end of the unlocking piece 34 abuts against the guide inclined surface of the second clamping block 33 to make the second clamping block 33 rotate around the rotating shaft 311. Of course, the position-adjustable unlocking piece 34 provided in the above embodiment can also be used to drive the second clamping block 33 to rotate. The rotation of the second clamping block 33 is transmitted to the first clamping block 32 through the rotating shaft 311, and the first clamping block 32 also rotates, so that the guide inclined surface of the first clamping block 32 gradually disengages from the clamping of the driving block 41. The other side (i.e., the first limiting rod 312 on the right side in the figure) can prevent the first clamping block 32 from rotating excessively when the unlocking piece 34 drives the second clamping block 33 to rotate, and ensure the rotation range of the first clamping block 32. Through the cooperation of the driving block 41 clamping the two first clamping blocks 32 in turn and the unlocking piece 34 driving the second clamping block 33 to make the first clamping block 32 disengage from the clamping, the reciprocating sliding of the sliding seat 31 on the workbench 10 is realized. Since the support frame 20 is installed at both sides of the sliding seat 31, the reciprocating sliding of the sliding seat 31 will drive the support frame 20 and the material plate 21 carrying the circuit board 1 on the support frame 20 to move together, so that the two ends of the support frame 20 are alternately slid to the glue injection station 11 to realize the continuous glue injection production of the circuit board 1.

[0056] Referring to Figures 3 to 5 In some embodiments of the present application, the driving assembly 40 comprises two sprockets 42 and a chain 43, the two sprockets 42 are spaced apart, the chain 43 can be wound around the two sprockets 42, the driving block 41 is arranged on the chain 43, and the sprockets 42 are configured to drive the chain 43 to transmit power, so that the chain 43 drives the driving block 41 to rotate and slide on the workbench 10.

[0057] Further, the embodiment of the present application optimizes the design of the driving assembly 40, and adopts the transmission mode of two sprockets 42 and a chain 43 to drive the driving block 41 to rotate and slide on the workbench 10. The overall structure takes the workbench 10 as the support foundation, and the sliding seat 31 and other components of the transmission assembly 30 are driven by the driving assembly 40 to realize the reciprocating movement of the supporting frame 20 on the workbench 10, thereby driving the circuit board 1 and the material plate 21 to move between the glue injection stations 11.

[0058] Specifically, the two sprockets 42 are spaced apart on the workbench 10 through bearings and other rotating connecting members, the bearings are installed in the center shaft holes of the sprockets 42, the center shafts of the sprockets 42 are fixed at both ends of the support of the workbench 10, and the sprockets 42 can stably rotate. The tooth shape of the sprocket 42 meets the transmission requirements of the chain 43, so as to ensure the meshing accuracy and transmission efficiency between the chain 43 and the sprocket 42. The chain 43 adopts a standard roller chain, which is composed of chain plates, pins, sleeves and rollers. The pitch of the chain 43 matches the pitch of the sprocket 42, so as to ensure that the chain 43 can be smoothly wound around the two sprockets 42. The chain plate of the chain 43 is made of high-quality steel and is treated on the surface to improve its corrosion resistance and wear resistance. The two ends of the chain 43 are connected by connecting pins to form a closed ring for circulating transmission between the two sprockets 42. The driving block 41 is a metal block with a certain shape and size, and its material can be selected according to actual needs, such as aluminum alloy, steel, etc. The driving block 41 is fixed on the chain link of the chain 43 by welding, bolt connection and other methods, so as to ensure the firm and reliable connection between the driving block 41 and the chain 43. The shape of the driving block 41 is designed to be able to be clamped with the first clamping block 32 of the transmission assembly 30, for example, one side of the driving block 41 is provided with a protrusion or a groove matched with the clamping part 321 of the first clamping block 32, so as to realize stable clamping transmission.

[0059] In order to drive the sprocket 42 to rotate, the embodiment further comprises a driving device (not shown in the figure). The driving device can be a motor, and the output shaft of the motor is connected to the center shaft of one of the sprockets 42 through a shaft coupling. The motor adopts a variable frequency motor, which can adjust the rotating speed according to the actual production needs, so as to control the transmission speed of the chain 43 and the rotating and sliding speed of the driving block 41. The motor is installed on a motor support, and the motor support is fixed on the workbench 10 to ensure the stable installation of the motor.

[0060] In actual work, first, the material plate 21 carrying the circuit board 1 is placed on the support frame 20. Start the motor, the motor drives one of the sprocket 42 to rotate through the shaft coupling, because the chain 43 is arranged on the two sprocket 42, so the rotation of the sprocket 42 will drive the chain 43 transmission. With the transmission of the chain 43, the driving block 41 fixed on the chain 43 also rotates and slides. When the driving block 41 moves to the position corresponding to the first clamping block 32 of the transmission assembly 30, the driving block 41 and the first clamping block 32 are clamped with each other. Because the driving block 41 has the power of rotary sliding under the drive of the chain 43, it will drive the sliding block 31 to slide along the slide rail on the workbench 10 through the first clamping block 32. With the continuous transmission of the chain 43, the driving block 41 drives the sliding block 31 to make reciprocating motion on the workbench 10. When the driving block 41 moves to the other end of the chain 43, because of the ring structure of the chain 43, the driving block 41 will continue to drive along the chain 43, realizing rotary sliding. At the same time, the other first clamping block 32 will enter the clamping state with the next driving block 41, driving the sliding block 31 to continue sliding again.

[0061] It can be understood that in order to drive the driving block 41 to rotate and slide on the workbench 10, the mechanism of the rotary slide rail can also be driven, so in this embodiment, the driving assembly 40 is not limited in specific structure.

[0062] Reference Figures 1 to 3 In some embodiments of the present application, the circuit board core positioning and glue injection transfer mechanism 2 further comprises a jacking assembly 50, the jacking assembly 50 is arranged on the workbench 10 and located below the glue injection station 11, the jacking assembly 50 comprises a jacking seat 51, the jacking seat 51 is arranged on the workbench 10 and located on the glue injection station 11, the jacking seat 51 is configured to jacking the material plate 21.

[0063] In this embodiment, the circuit board core positioning and glue injection transfer mechanism 2 is additionally provided with the jacking assembly 50, which is arranged on the workbench 10 and located below the glue injection station 11. When the material plate 21 moves to the glue injection station 11, the jacking assembly 50 can jacking the material plate 21, so as to carry out the glue injection operation.

[0064] The jacking assembly 50 is fixed on the workbench 10 through a mounting frame (not shown in the figure). The mounting frame is welded by section steel, and its shape and size are designed according to the mounting requirements of the jacking assembly 50. The bottom of the mounting frame is fixedly connected with the workbench 10 through bolts and other connecting members, so as to ensure that the jacking assembly 50 is installed firmly and reliably.

[0065] Specifically, in actual work, first, the material plate 21 carrying the circuit board 1 is placed on the support frame 20. The transmission assembly 30 drives the support frame 20 and the material plate 21 thereon to reciprocate on the workbench 10. When the material plate 21 moves to the glue injection station 11, the support frame 20 stops moving because it loses the driving of the driving block 41. At this time, the lifting seat 51 is driven upward. Since the lifting seat 51 is located on the glue injection station 11 and its shape and size match the material plate 21, the lifting seat 51 will contact and lift the material plate 21. After the material plate 21 is lifted, the distance between the material plate 21 and the glue injection head of the glue injection equipment reaches a suitable glue injection position, and the glue injection equipment starts to inject glue on the circuit board 1. During the glue injection process, the lifting seat 51 remains stable to ensure that the position of the material plate 21 does not change, so as to ensure the precision and quality of the glue injection. When the glue injection is completed, the lifting seat 51 moves downward, and the material plate 21 is placed on the support frame 20 again. The support frame 20 leaves the glue injection area under the sliding of the driving block 41, so as to perform subsequent operations.

[0066] Further, with reference to Figures 1 to 3 In some embodiments of the present application, the lifting assembly 50 includes two groups of lever members 52, which are respectively arranged on the workbench 10 and located on both sides of the support frame 20. One end of each group of lever members 52 is hingedly connected to the lower end of the lifting seat 51, and the other end of each group of lever members 52 is arranged on the two sides of the glue injection station 11 in a lifting manner. One side of the two ends of the support frame 20 is provided with a driving slope 53, which is configured to drive the other end of the lever member 52 to descend, so that the one end of the lever member 52 lifts the lifting seat 51 upward.

[0067] In this embodiment, the lifting assembly 50 uses two groups of lever members 52 to realize the lifting of the lifting seat 51. When the material plate 21 moves to the glue injection station 11, the driving slope 53 on the support frame 20 cooperates with the lever member 52 to drive the lever member 52 to move, thereby lifting the material plate 21 by the lifting seat 51 for glue injection operation.

[0068] The workbench 10 has space for installing the lever 52 on both sides and below the glue injection station 11, and corresponding support structures (not shown in the figure) are provided for installing and fixing the lifting end of the lever 52. Two sets of levers 52 are provided on the workbench 10 and located on both sides of the support frame 20. The lever 52 is made of metal material with certain strength and rigidity, such as alloy steel. Each set of levers 52 includes a lever (not shown in the figure), the middle part of the lever is provided with a hinge point, so that the lever can rotate around the hinge shaft, and the two ends of the lever are respectively hinged with lifting rods, the lower ends of the lifting rods are respectively hinged with the two ends of the lever, and the upper end of one of the lifting rods is hinged with the bottom of the lifting seat 51, and the other lifting rod can be used to abut against the driving slope 53 of the support frame 20. The hinge point of the lever is provided with a hinge shaft and a bearing to ensure the flexible rotation between the lever and the lifting seat 51. The lifting rod abutting against the driving slope 53 of the support frame 20 can be used as the lifting end and is arranged on both sides of the glue injection station 11 in a lifting manner. The bottom of the lifting seat 51 is connected with one end of the two sets of levers 52 in a hinged manner, and when the lever 52 rotates around the hinge shaft, it can drive the lifting seat 51 to move up and down. Support structures are provided on both sides of the glue injection station 11 on the workbench 10 for supporting and guiding the lifting end of the lever 52. The support structure can adopt the structure forms of a sleeve ring, a sliding rail and a sliding block, etc., so that the lifting end of the lever 52 can lift along a predetermined track. For example, vertical sleeve rings are installed on the workbench 10 on both sides of the glue injection station 11, the lifting rods of the lever 52 are arranged in the sleeve rings, and the lifting rods at both ends of the lever can slide up and down in the sleeve rings, thereby ensuring the stability and accuracy of the lifting of the lever 52.

[0069] In actual work process, first, the material plate 21 carrying the circuit board 1 is placed on the support frame 20. The transmission assembly 30 drives the support frame 20 and the material plate 21 thereon to reciprocate on the workbench 10, and when the material plate 21 moves to the glue injection station 11, the driving block 41 is separated from the first clamping block 32, and the support frame 20 stops moving. At this time, the driving slopes 53 at both ends of the support frame 20 are in contact with the upper ends of the lifting rods of the two sets of levers 52. With the downward pressure of the driving slope 53 on the lifting rod of the lever, the lever rotates around the hinge shaft in the middle part. Since the lifting rod at the other end of the lever is hinged with the lower end of the lifting seat 51, according to the lever principle, the descent of the other end of the lever will drive the other end to move upward, thereby lifting the lifting seat 51. After the lifting seat 51 is lifted, it will contact and lift the material plate 21, so that the distance between the material plate 21 and the glue injection head of the glue injection mechanism reaches a suitable glue injection position, and the glue injection equipment starts to inject glue on the circuit board 1. During the glue injection process, the lifting seat 51 remains stable to ensure that the position of the material plate 21 does not change, so as to ensure the precision and quality of the glue injection.

[0070] When the glue injection is completed, the transmission assembly 30 drives the supporting frame 20 and the material plate 21 thereon to leave the glue injection station 11. At this time, the driving slope 53 is separated from the lifting rod of the lever member 52, the lever member 52 is restored to the initial position under the action of its own gravity or other reset devices (such as springs, etc., which can be selected according to the actual design requirements whether to be set), and the jacking seat 51 also descends, and the material plate 21 is placed on the supporting frame 20 again. The transmission assembly 30 continues to drive the supporting frame 20 and the material plate 21 thereon to move to the next glue injection station 11 or leave the glue injection area, so as to carry out subsequent operations.
