Description

Technical Field

[0001] The present invention relates to the technical field of battery tray processing equipment, and in particular to a positioning tool and a gluing process for gluing a battery tray of a new energy vehicle. Background Art

[0002] The gluing process is a key step in the production of battery trays for new energy vehicles. It is not only related to the sealing, safety and durability of the battery, but also directly affects the overall performance of the vehicle. The sealing and mechanical strength of the battery tray are ensured through precise gluing technology. However, there are some problems with the current technical situation. As far as the existing battery tray gluing process is concerned, the tray is exposed to the air environment for most of the time during the gluing process. When the gluing machine is running, dust and impurities in the external environment are very likely to fall on the tray and the glue being applied. This situation seriously affects the gluing effect and causes the glue and tray to be glued together. The bonding quality of the tray is poor, which may affect the important properties of the battery tray, such as the sealing and structural stability. The entire gluing process does not have an effective protective effect, and cannot avoid the interference of external factors on the gluing process and the protection of operators; moreover, in the conveying link of the pallet, its accuracy is insufficient, and the use effect in clamping and positioning needs to be improved. This insufficient accuracy may cause inaccurate conveying and gluing positions, and poor clamping and positioning effects are not conducive to the stability of the gluing process. Therefore, it is urgent to propose a positioning tool and gluing process for gluing new energy vehicle battery trays to improve the existing technology. Summary of the invention

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a positioning tool for gluing a battery tray of a new energy vehicle to solve the problems mentioned in the above background technology.

[0004] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical scheme: a positioning tool for gluing a battery pallet of a new energy vehicle, comprising a pallet, a frame, a gluing area arranged on the upper side of the frame, and a glue supply device for supplying materials to the gluing area, a gluing machine head is movably arranged inside the gluing area, the gluing area comprises an upper protective transparent cover installed on the upper side of the frame and a removable and installed upper protective transparent cover mounted on the upper side of the lower frame, the gluing machine head is movably arranged on the inner side of the upper protective transparent cover and the lower frame, a closing plate is locked on one side of the bottom of the lower frame, a pallet socket matching the shape of the upper edge of the pallet is opened in the middle of the closing plate, a conveying bracket is longitudinally interspersed in the middle of the frame, the conveying bracket is equipped with a conveyor belt for conveying the pallet, and the conveyor belt is located directly below the pallet socket, and the conveying bracket below the pallet socket is provided with a lifting and positioning component for positioning and lifting the pallet;

[0006] The front and rear sides of the lifting plate are movably provided with clamping members, the upper horizontal plane of the clamping members is higher than the upper horizontal plane of the lifting plate, when the tray is located below the tray insertion port, the two clamping members rise to the front and rear sides of the tray to clamp the tray, and the two clamping members are relatively displaced to clamp the tray front and rear and correct the position;

[0007] The two shaped mounting seats are both laterally installed with two transverse telescopic rods, and the telescopic ends of the two transverse telescopic rods are vertically installed with guide clamping plates, and the top ends of the guide clamping plates are adjacently arranged on the lower side of the closing plate. When the two clamping members clamp and correct the position of the pallet front and back, the transverse telescopic rods of the two shaped mounting seats shrink relatively synchronously, and the guide clamping plates relatively displace to clamp and correct the left and right sides of the pallet, so that the pallet corresponds to the position of the pallet socket. At this time, the lifting plate lifts the pallet and guides it to slide upward along the two guide clamping plates and insert it into the pallet socket for sealing and gluing.

[0008] A further improvement based on the above technical solution is that airbag rings are provided on the upper and lower edges of the tray socket, and the frame is equipped with a first air pump, and the first air pump is connected to the airbag ring through an air pipe. When the upper side of the tray is inserted into the tray socket, the airbag ring fits tightly with the outer side of the pallet under the blowing and expansion action of the first air pump.

[0009] A further improvement based on the above technical solution is that a second air pump is installed on the lower side of the frame, and the second air pump is connected to the inner side of the lower frame through an air pipe. The suction action of the second air pump forms a negative pressure environment inside the entire closed glue coating area.

[0010] A further improvement based on the above technical solution is that a plurality of negative pressure suction cups are arranged side by side on the lifting plate, a vertical guide rod is installed at the bottom of the lifting plate, and the vertical guide rod is penetrated by the conveying bracket, a third air pump is installed on the lower side of the frame, the third air pump is connected to each negative pressure suction cup through an air pipe, and the lifting plate is adsorbed and connected to the lower side of the tray through the plurality of negative pressure suction cups.

[0011] A further improvement based on the above technical solution is that a bidirectional telescopic rod is longitudinally installed in the middle of the lifting plate, and the front and rear telescopic ends of the bidirectional telescopic rod are respectively connected to two clamping members.

[0012] A further improvement based on the above technical solution is that the clamping piece includes a tube, a movable rod is slidably inserted into the upper side of the tube, and a return spring is connected to the movable rod and the inner side of the tube, a longitudinal guide rod is fixedly provided on one side of the tube, and the longitudinal guide rod is movably inserted from one side of the lifting plate, when the clamping piece moves upward and presses against the lower side of the closing plate, the movable rod retracts under the action of the return spring, and the movable rod is continuously clamped on the front and rear sides of the pallet.

[0013] A further improvement based on the above technical solution is that the opposite side of the two guide clamps is a smooth surface, and a transverse guide rod is laterally fixed on the other side of the upper side of the guide clamp, and the transverse guide rod is slidably inserted by the frame and limits the front and rear positions of the conveying bracket in the middle of the frame.

[0014] A further improvement based on the above technical solution is that a guide rod group is provided on both sides of the conveyor belt, and the guide rod group includes two shaped guide rods that are relatively outward, and the turning angles of the shaped guide rods are rounded. Two connecting rods are fixed on the front side of the frame, and the two connecting rods are respectively equipped with a plurality of relatively arranged telescopic adjustment rods, and the two shaped guide rods are respectively connected to the telescopic adjustment rods of the two connecting rods.

[0015] A further improvement based on the above technical solution is that a movable beam for movably mounting a gluing machine head is provided on the inner side of the lower frame, a longitudinal linear driving mechanism for driving the longitudinal displacement of the gluing machine head is provided on the upper side of the movable beam, a transverse linear driving mechanism for driving the transverse displacement of the movable beam is installed on the inner side of the lower frame, and a heating lighting lamp is installed on the lower side of the movable beam.

[0016] It also includes a gluing process of a positioning tool for gluing a new energy vehicle battery tray, comprising the following steps:

[0017] 1: Pallet conveying stage: Place a pallet with a width greater than the conveyor belt on the conveyor belt for conveying until the pallet is conveyed to the bottom of the closing plate and detected by the corresponding sensor, and the conveyor belt stops conveying;

[0018] 2: Pallet alignment and clamping stage: The lifting plate rises upward, so that the clamping parts on the front and rear sides rise upward respectively and are located on the front and rear sides of the pallet respectively. The pallet is pushed, corrected and clamped by the relative displacement of the two clamping parts on the front and rear sides. At this time, the lateral telescopic rods of the two shaped mounting seats are relatively contracted, pulling the corresponding two guide clamping plates to relatively displace, thereby forming a vertical guide channel while pushing and correcting the positions of the left and right sides of the pallet;

[0019] 3: Pallet guide lifting stage: After the front, back, left and right positions of the pallet are corrected, the pallet is now directly below the pallet socket, and the lifting telescopic rod pushes the lifting plate upward, allowing the two lifting plates to lift the bottom surface of the pallet. While lifting, the clamping parts on the front and back sides of the pallet still maintain front and back clamping, and the guide plates on the left and right sides of the pallet also maintain the left and right limit function, and allow the lifted pallet to stably move upward along the guide channel between the two guide plates until the upper part of the pallet that needs to be glued is inserted into the pallet socket, and the upper side of the convex edge of the lower part of the pallet is tightly attached to the lower side of the closing plate, so that the upper part of the pallet is stably in the gluing area while the entire gluing area is closed;

[0020] 4: Gluing stage: Then control the glue coating head to move forward, backward, left and right in the lower frame. Under the action of the glue supply device, the glue coating head applies glue to the upper side of the tray at the tray insertion port. When applying glue, the entire closed glue coating area forms a negative pressure to eliminate bubbles in the glue, and the gluing work can be visually observed from the upper protective transparent cover;

[0021] 5: Reset and discharge stage: After the glue is applied, the telescopic rod is lifted and the lifting plate is pulled down to reset, so that the pallet clamped by the front and rear clamping parts moves downward along the two guide plates and is placed on the conveyor belt again, and can be quickly transported to the next process through the conveyor belt.

[0022] By adopting the above technical solution, the present invention has the following advantages compared with the existing technology:

[0023] The present invention is provided with an upper protective transparent cover on the upper side of the lower frame to form a relatively closed gluing area, so that the gluing machine head can perform gluing work on the pallet. The upper protective transparent cover can effectively prevent external dust and impurities from entering the gluing area, thereby improving the gluing effect and the bonding quality of the glue and the pallet. The working situation can be observed through the protective transparent cover, and the safety of the operator is improved.

[0024] A tray socket that matches the shape of the upper edge of the tray is provided at the bottom of the lower frame, and a lifting and positioning assembly is provided in the middle of the conveying bracket, so that the lifting and lifting plate of the lifting and positioning assembly can not only stably lift the tray and insert it into the tray socket, but the tray socket can not only accurately position the tray, but the design can also form a completely enclosed space in the gluing area, and with the suction effect of the second air pump, negative pressure can be formed in the gluing area. The negative pressure environment helps to suppress the bubbling of the glue, and also helps the glue to penetrate and adhere better, so that the glue fits the surface of the tray more closely, thereby improving the adhesion between the glue and the surface of the tray, so that the glue forms a more uniform and dense coating on the pallet, thereby enhancing the sealing and structural fixing effect of the glue, thereby improving the overall performance of the battery tray.

[0025] Airbag rings are arranged at the upper and lower edges of the tray socket, and the airbag rings can be tightly fitted with the outer side of the tray under the blowing and expansion action of the first air pump, which not only further improves the applicability of the tray socket size, does not wear the tray surface, and strengthens the sealing effect of the gluing area, and can better prevent external dust, moisture and other pollutants from entering the gluing area. At the same time, in the process of the airbag ring tightly fitting with the outer side of the tray, it also plays a certain role in tightening and positioning assistance, which is beneficial to the stability of the gluing work, and combines the role of the lifting and positioning component to achieve multiple positioning clamping;

[0026] The present invention installs a negative pressure suction cup on the lifting plate, and the negative pressure suction cup quickly absorbs the bottom surface of the tray under the action of the third air pump, which can provide additional fixing force to ensure that the tray will not be displaced during the gluing process, thereby improving the accuracy and quality of gluing, and the rapid absorption and release capabilities of the negative pressure suction cup can realize rapid tray replacement and positioning, thereby improving the production efficiency of the entire gluing process;

[0027] The lifting plate not only plays the role of sucking and lifting the pallet, but also the clamping parts on the front and rear sides of the lifting plate can be respectively moved to the front and rear sides of the pallet, and relatively moved under the action of the two-way telescopic rod, so as to clamp and correct the position of the pallet front and back, and cooperate with the two guide clamping plates to push the limit left and right to achieve the rapid positioning of the pallet on the lifting plate front and back, and at the same time, when the lifting plate lifts the pallet upward, the pallet can be inserted upward into the pallet socket along the guide channel between the two guide clamping plates, which is accurate and stable to use;

[0028] Among them, the movable rod of the clamping piece is elastically slid into the tube through the return spring. Therefore, when the clamping piece moves upward with the pallet and presses against the lower side of the closing plate, the movable rod retracts in the tube under the action of the return spring, thereby adapting to different height changes. On the contrary, when the pallet moves downward, the movable rod can be extended upward under the action of the return spring, and the movable rod can always be kept clamped on the front and rear sides of the pallet for positioning, which is more flexible and changeable to use; and when the clamping piece clamps the pallet, the two guide plates push the pallet to move left and right relative to each other. Since the movable rod is rotatably inserted into the tube, the movable rod can rotate with the left and right displacement of the pallet, reducing the friction between them, and the adjustment of the position is smoother and more stable.

DETAILED DESCRIPTION

[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0041] like Figure 1-9As shown, the present invention provides a technical solution for positioning tooling for gluing a battery tray of a new energy vehicle: it comprises a tray a, a frame 1, a gluing area 2 arranged on the upper side of the frame 1, and a glue supply device 3 for supplying material to the gluing area 2, a gluing machine head 20 is movably arranged inside the gluing area 2, the gluing area 2 comprises a lower frame 22 installed on the upper side of the frame 1 and an upper protective transparent cover 21 which is detachably mounted and sleeved on the upper side of the lower frame 22, the gluing machine head 20 is movably arranged inside the upper protective transparent cover 21 and the lower frame 22; the combination of the upper protective transparent cover 21 and the lower frame 22 forms a relatively independent gluing space, which can protect the gluing machine head 20 and prevent the glue splashing during the gluing process from affecting the outside world, the transparent cover is convenient for operators to observe the gluing situation, and is convenient for equipment maintenance or adjustment when necessary, and the internal components of the gluing area can be easily inspected and repaired by disassembling and installing;

[0042] A closed plate 23 is locked on one side of the bottom of the lower frame 22, and a tray socket 24 matching the shape of the upper edge of the tray a is opened in the middle of the closed plate 23. The tray socket 24 can be changed according to the shape of the tray a. A conveying bracket 41 is longitudinally inserted in the middle of the frame 1. The conveying bracket 41 is installed with a conveyor belt 4 for conveying the tray a. The conveyor belt 4 realizes the conveyance of the tray a, and the conveyor belt 4 is located directly below the tray socket 24; guide rod groups 6 are provided on both sides of the conveyor belt 4. The guide rod group 6 It includes two L-shaped guide rods 61 facing outwards, and the turning angle of the L-shaped guide rods 61 is rounded. Two connecting rods 62 are fixed on the front side of the frame 1, and the two connecting rods 62 are respectively installed with a plurality of relatively arranged telescopic adjustment rods 63. The two L-shaped guide rods 61 are respectively connected to the telescopic adjustment rods 63 of the two connecting rods 62. The L-shaped guide rods 61 are clamped on the left and right sides of the pallet a, so that the conveyor belt 4 can perform preliminary guidance when feeding, to prevent the pallet a from being offset during the conveying process and affecting the subsequent positioning work.

[0043] In addition, the conveying bracket 41 below the tray socket 24 is provided with a lifting and positioning assembly 5 for positioning and lifting the tray a. The lifting and positioning assembly 5 includes two H-shaped mounting seats 51 relatively mounted on the left and right sides of the conveying bracket 41. The conveyor belt 4 is displaced between the two H-shaped mounting seats 51. A lifting telescopic rod 52 is vertically mounted in the middle of the H-shaped mounting seat 51. The telescopic end of the lifting telescopic rod 52 is locked with a lifting plate 53 for horizontally contacting the bottom surface of the tray a, which is used to lift the tray a and insert it into the tray socket 24, so that a closed space is formed in the glue coating area 2; the front and rear sides of the lifting plate 53 A clamping piece 57 is movably provided respectively, and the upper horizontal plane of the clamping piece 57 is higher than the upper horizontal plane of the lifting plate 53. When the tray a is located below the tray insertion opening 24, the two clamping pieces 57 rise to the front and rear sides of the tray a to clamp the tray a, and the two clamping pieces 57 are relatively displaced to clamp the tray a front and rear and correct the position. A bidirectional telescopic rod 56 is longitudinally installed in the middle of the lifting plate 53, and the front and rear telescopic ends of the bidirectional telescopic rod 56 are respectively connected to the two clamping pieces 57; two H-shaped mounting seats 51 are transversely installed with two transverse telescopic rods 54, and the two transverse telescopic rods 54 are extended to the rear of the tray a. A guide clamping plate 55 is vertically installed at the retracted end, and the top end of the guide clamping plate 55 is adjacent to the lower side of the closing plate 23. When the two clamping members 57 clamp and correct the position of the tray a in the front and back directions, the transverse telescopic rods 54 of the two H-shaped mounting seats 51 are synchronously relatively contracted, and the guide clamping plate 55 is relatively displaced to clamp and correct the left and right sides of the tray a, so that the tray a corresponds to the position of the tray socket 24. That is to say, when the tray a reaches the bottom of the tray socket 24, the clamping member 57 in the lifting positioning assembly 5 and the guide clamping plate 55 clamp and correct the position of the tray a from the front and back directions and the left and right directions, and the clamping member 57 The front and rear directions of pallet a are precisely corrected by driving the bidirectional telescopic rod 56. The guide plate positions pallet a in left and right directions under the action of the transverse telescopic rod 54. The lifting plate 53 lifts pallet a, guides it to slide upward along the two guide plates 55 and inserts it into the pallet socket 24 for closed gluing. This multi-directional positioning and correction enables pallet a to accurately correspond to the position of the pallet socket 24. This series of actions ensures that pallet a can be accurately inserted into the pallet socket 24, providing precise pallet positioning for subsequent gluing work and ensuring the accuracy of the gluing position.

[0044] In this embodiment, airbag rings 25 are provided on both upper and lower edges of the tray socket 24, and the frame 1 is installed with a first air pump 26, which is connected to the airbag ring 25 through an air pipe. When the upper side of the tray a is inserted into the tray socket 24, the airbag ring 25 is tightly fitted with the outer side of the tray a under the blowing and expansion action of the first air pump 26. That is to say, when the tray a is inserted into the tray socket 24, the first air pump 26 blows and expands the airbag ring 25 to tightly fit the outer side of the tray a, further enhancing the sealing and clamping positioning effect at the tray socket 24, preventing external dust, impurities, etc. from entering the gluing area 2, ensuring the cleanliness of the gluing environment, and improving the gluing quality. At the same time, the setting of the airbag ring 25 will not be in rigid contact with the top of the tray a, reducing the wear between them;

[0045] In the above technical solution, a second air pump 27 is installed on the lower side of the frame 1, and the second air pump 27 is connected to the inner side of the lower frame 22 through an air pipe. The suction action of the second air pump 27 forms a negative pressure environment inside the entire closed gluing area 2. During the gluing process, if air is mixed in the glue or bubbles are generated during the gluing operation, then in the negative pressure environment, the bubbles are more easily sucked out or suppressed. This is because the negative pressure will cause the air in the glue to diffuse to the external environment with lower pressure, reduce the bubble content inside the glue, and also increase the adhesion between the glue and the tray a, thereby improving the sealing and quality of the gluing.

[0046] In this embodiment, a plurality of negative pressure suction cups 531 are arranged side by side on the lifting plate 53, a vertical guide rod 532 is installed at the bottom of the lifting plate 53, and the vertical guide rod 532 is penetrated by the conveying bracket 41, and a third air pump 28 is installed on the lower side of the frame 1, and the third air pump 28 is connected to each negative pressure suction cup 531 through an air pipe. The lifting plate 53 is adsorbed and connected to the lower side of the tray a through the plurality of negative pressure suction cups 531. When the tray a is located on the lifting plate 53, the third air pump 28 enables the negative pressure suction cup 531 to adsorb the lower side of the tray a, thereby increasing the stability of the tray a during the gluing process, further preventing the displacement of the tray a during the gluing operation, and ensuring the uniformity and continuity of the gluing. When the tray a is stuck in the tray socket 24, the negative pressure suction cup 531 has the function of pulling the tray a downward, thereby improving the stability in use.

[0047] Among them, the clamping member 57 includes a tube 571, a movable rod 572 is slidably inserted into the upper side of the tube 571, and the movable rod 572 is connected to the inner side of the tube 571 with a return spring 573. Since the movable rod 572 is rotatably inserted into the tube 571, the movable rod 572 can rotate with the left and right displacement of the tray a, which can reduce the friction between them and make the position adjustment smoother and more stable. A longitudinal guide rod 574 is fixed on one side of the tube 571, and the longitudinal guide rod 574 is movably inserted from one side of the lifting plate 53. When the clamping member 57 moves upward and presses against the lower side of the closing plate 23, the movable rod 572 retracts under the action of the return spring 573, and the movable rod 572 is continuously clamped on the front and rear sides of the tray a. This structure enables the clamping member 57 to reliably clamp the front and rear sides of tray a when tray a reaches the appropriate position, and the setting of the return spring 573 ensures the stability of the clamping of the movable rod 572. Even when it is disturbed by a certain external force, it can continue to clamp tray a, which helps to accurately position and stably fix tray a. That is, when the clamping member 57 rises, it will resist the closing plate 23 and may limit the entire lifting plate 53 from continuing to lift upward. However, by setting the movable rod 572 to be elastically retractable up and down, it will not affect the upward lifting of the lifting plate 53. On the contrary, the movable rod 572 can be flexibly retracted and retracted, and the front and rear sides of tray a can always be kept clamped regardless of whether tray a is rising or falling.

[0048] As a further improvement, the opposite sides of the two guide plates 55 are smooth surfaces, and a transverse guide rod 551 is laterally fixed to the other side of the upper side of the guide plates 55. The transverse guide rod 551 is slidably inserted by the frame 1, and the conveying bracket 41 is limited in the front and rear positions in the middle of the frame 1. In this way, the smooth surface on the opposite side of the guide plates 55 is conducive to the smooth sliding and rising of the tray a therebetween, reducing the influence of friction on the rising process of the tray a. The setting of the transverse guide rod 551 not only ensures the stable displacement of the guide plates 55 in the transverse direction, but also limits the conveying bracket 41 in the middle of the frame 1, thereby improving the stability of the entire device structure.

[0049] A movable beam 201 for movably mounting the glue coating head 20 is provided on the inner side of the lower frame 22, a longitudinal linear drive mechanism 202 for driving the longitudinal displacement of the glue coating head 20 is provided on the upper side of the movable beam 201, and a transverse linear drive mechanism 203 for driving the transverse displacement of the movable beam 201 is installed on the inner side of the lower frame 22. The longitudinal linear drive mechanism 202 and the transverse linear drive mechanism 203 can accurately control the longitudinal and transverse displacements of the glue coating head 20 on the surface of the pallet a to meet different gluing trajectory requirements and are suitable for pallets a of various shapes and gluing pattern requirements, and a heating lamp 204 is installed on the lower side of the movable beam 201. The heating lamp 204 is an external irradiation lamp. The heating function of the heating lamp 204 can preheat and dry the surface of the pallet a before gluing, and its lighting function during gluing makes it convenient for the operator to observe the gluing situation, discover problems in time and make adjustments. At the same time, the glue that needs to be cured can be heated and cured according to the use requirements to ensure that the glue can be quickly cured and achieve the best performance.

[0050] The present invention also includes a gluing process of a positioning tool for gluing a battery tray of a new energy vehicle:

[0051] S1: Pallet conveying stage: by placing a pallet a whose width is greater than that of the conveyor belt 4 on the conveyor belt 4 for conveying, until the pallet a is conveyed to the bottom of the closing plate 23 and is detected by the corresponding sensor, the conveyor belt 4 stops conveying;

[0052] S2: Pallet alignment and clamping stage: The lifting and telescopic rods 52 of the two H-shaped mounting seats 51 drive the lifting and lifting plate 53 upward to lift the front and rear clamping members 57 upward respectively.

[0053] The two clamping members 57 on the front and rear sides of the tray a are respectively located at the front and rear sides, and the two clamping members 57 on the front and rear sides are pulled to move relative to each other through the bidirectional telescopic rod 56, and the movable rod 572 of the clamping member 57 is used to push and correct the front and rear positions of the tray a and clamp the tray a. At this time, the transverse telescopic rods 54 of the two H-shaped mounting seats 51 are relatively contracted, and the corresponding two guide clamping plates 55 are pulled to move relative to each other, so that a vertical guide channel is formed while pushing and correcting the positions of the left and right sides of the tray a. When the tray a moves left and right, since the movable rod 572 is rotated and inserted into the tube 571, the movable rod 572 can rotate with the left and right displacement of the tray a, which can reduce the friction between them and make the position adjustment smoother and more stable.

[0054] S3: Pallet guide lifting stage: After the front, rear, left and right positions of pallet a are corrected, pallet a is now directly under the pallet socket 24, and the lifting telescopic rod 52 pushes the lifting plate 53 upward again, allowing the negative pressure suction cups 531 of the two lifting plates 53 to contact the lower side of pallet a. The negative pressure suction cups 531 quickly adsorb the bottom surface of pallet a under the action of the third air pump 28, which is enough to provide additional adsorption and fixing force to ensure that pallet a will not move during the gluing process. While the lifting plate 53 lifts pallet a, the clamping members 57 on the front and rear sides of pallet a still maintain the front and rear clamping, and the guide clamping plates 55 on the left and right sides of pallet a also maintain the left and right limiting function, and allow the lifted pallet a to stably move upward along the guide channel between the two guide clamping plates 55. When the clamping member 57 moves upward with pallet a and presses against the lower side of the closing plate 23, the movable rod 572 retracts into the tube 571 under the action of the return spring 573, maintaining While achieving the clamping effect, it avoids hindering the upward displacement of the lifting plate 53 until the upper part of the pallet a that needs to be glued is inserted into the pallet socket 24, that is, it is inserted from the inner side of the airbag ring 25 to close the entire gluing area 2, and the upper side of the convex edge of the lower part of the pallet a is tightly attached to the lower side of the closing plate 23, so that the upper part of the pallet a is stably and airtightly in the gluing area 2, and then at this time, the airbag ring 25 can be tightly fitted with the outer side of the pallet a under the blowing and expansion action of the first air pump 26. The swollen state of the airbag ring 25 can not only improve the applicability of the size of the pallet socket 24, reduce the wear on the surface of the pallet a, and enhance the sealing effect of the gluing area, and can better prevent external dust, moisture and other pollutants from entering the gluing area. At the same time, in the process of the airbag ring 25 being tightly attached to the outer side of the pallet a, it also plays a certain tightening and positioning auxiliary role, which is beneficial to the stability of the gluing work, and combined with the role of the lifting and positioning component 5 to achieve multiple positioning clamping;

[0055] S4: Gluing stage: Then the glue coating head 20 is controlled by the longitudinal linear drive mechanism 202 and the transverse linear drive mechanism 203 to move forward, backward, left and right in the lower frame 22. Under the action of the glue supply device 3, the glue coating head 20 applies glue to the upper side of the tray a at the tray socket 24. When applying glue, the second air pump 27 is used to pump air, so that a negative pressure can be formed in the glue coating area 2. The negative pressure environment helps to suppress the bubbling of the glue, and also helps the glue to penetrate and adhere better. The glue fits the surface of the tray more closely, and the adhesion between the glue and the surface of the tray is improved. The heating lighting lamp 204 can be turned on as needed. Its lighting function makes it convenient for the operator to observe the glue coating situation. The glue that needs to be cured after gluing can also be heated and cured to ensure that the glue can be quickly cured and achieve the best performance. During this period, the working condition of the equipment gluing can be directly observed from the upper protective transparent cover 21;

[0056] S5: Reset and discharge stage: After the glue coating is completed, the second air pump 27 releases the pressure, and the lifting telescopic rod 52 combines with the negative pressure suction cup 531 on the lifting plate 53 to pull the lifting plate 53 downward to reset, so that the pallet a clamped by the front and rear clamping members 57 can slide downward along the guide channel between the two guide clamping plates 55. At this time, after the movable rod 572 is separated from the closing plate 23, it can be gradually extended upward under the action of the return spring 573, and return to the position of clamping the front and rear sides of the pallet a, and always keep the movable rod 572 clamped on the front and rear sides of the pallet a to avoid displacement during descent, until the pallet a is placed on the conveyor belt 4 again, and then release the pressure of the negative pressure suction cup 531, the movable rod 572 moves downward below the bottom surface of the pallet a, and opens the two guide clamping plates 55, so that it can be quickly transported to the next process through the conveyor belt 4.

[0057] It should be noted that the positioning tool for gluing the battery tray of a new energy vehicle of the present invention mainly improves the above-mentioned structure. The functions, components and structures not mentioned therein can be implemented by using components and structures in the prior art that can realize the corresponding functions. For example, the longitudinal linear drive mechanism 202 and the transverse linear drive mechanism 203 are linear slides, which are prior art. The main driving principle is to convert the rotational motion of the motor into the linear motion of the slider by a motor-driven transmission system such as a ball screw or a screw, thereby realizing the longitudinal and transverse linear motion of the gluing machine head 20 and the movable beam 201, so they will not be elaborated here.

Without departing from the principle of the present invention, those skilled in the art may also make many variations and improvements, which should also be considered as the protection scope of the present invention.
